The appearance of the multi-functional folding drawing board is kind of drawing board, some light materials like basswood and rigid plastics are used in main structure of the drawing board to make it light and convenient to carry. The main structure can be folded and it is suitable for A1 and A2 drawings. In the designing procedure, dip angle adjusted mechanism by worm wheel and gear, magnetic pull-in mechanism, leading rail, slide-way, drawer, tool library, paper bag and horn locks are applied based on modularity designing theory. Finite element analysis of key components of drawing board is analyzed. Keywords: folding drawing board, structure design, multi- functional, TRIZ theory 1. Introduction The drawing board is used to place the drawing and provide the user with a tidy drawing area. It is born with the need of the human beings manual drawing. According to the statistics, about 37 million work on drawing work or study, and the amount of the drawing workers is rising by years. With the development of science and technology, the request of improvement of the quality of manual drawing and the conveniences, security and reliability of the auxiliary tools is prominent. The quality of manual drawing is closely related to the conveniences, security and reliability of the auxiliary tools. At present, there are many innovative products on the market. The mainstream products can be divided into two types, multi-boards combination and single-board. The function of present drawing board on the market is too simple to satisfy the individuation needs of different designers. Disadvantages of present structure are as follows: (1) Not convenient to carry with plenty of drawing instruments, easy to omit, even lose, not only brings financial loss but also influence the following drawing works. (2) Core drawing function of the drawing board is simple. And the dip angle is fixed or limited adjustment. (3) Volume of present drawing desk is big and inefficiency of using. At the same time, ordinary drawing board has to be used with drawing desk, the dip angle cannot be adjusted when single used. (4) Drawing instruments have to be carried alone.

2 So, how to improve the function of the drawing board to satisfy the diversification need of the consumers is the hotspot which the auxiliary drawing tools designers focus on and has a great real value. 2. TRIZ Theory TRIZ theory originates from the former Soviet Union. In 1946, G. S. Altshuller and his colleagues on the basis of researching in more than 250 million copies of the patent documentations around the world, and found the law behind these inventions. TRIZ is an abbreviation of Russia Theoria Resheneyva Isobretatelskehuh Zadach, which means Theory of Innovative Problem Solving (TIPS). It is a methodology to create systematic innovation and improve the thinking process of designer [1, 2]. Research and application of TRIZ in China has just started, after 2000, a lot of domestic scientific research institutions, enterprises and experts began to pay attention to TRIZ. Heilongjiang is the first province in China to TRIZ methods popularization and application promotion. In 2007 Heilongjiang province and Russia s TRIZ research institutions have worked together to trained chief executive leaders of science and company technology, those leader come from various places of Heilongjiang province, and popularized the theory of TRIZ, and in the patent application and technological innovation have made remarkable achievements [3-5]. TRIZ theory is a solution to the method of the invention issues and ultimately achieve innovation, also a kind of sharing numerous inventor s knowledge and experience to increase the project personnel innovation ability method [6-7]. The status of the problem Definition and analysis of the problem Solving the standard problrm Solving the standard problrm Predicting a future system Solving the contradiction problrm Improving the interaction of substances Formation of good skill ARIZ Prediction Technical Physical contradiction contradiction Inventive principle Separation principle Su-Field model Standardization Function model Effects Thinking process for novel solving the problem Evolution law of technology system Analysis and flexible use of resources Ideal final result Figure 1. Method of Solving the Problem using TRIZ TRIZ theory is a problem resolution system on the basis of evolution law of technology system. The theory and method architecture of TRIZ is consist of eight evolution law of technology system, thirty-nine general engineering parameters, forty inventive principles, thirty-nine multiple thirty-nine contradiction matrix, seventy-six standard solutions, algorithm for inventive-problem solving (ARIZ) and engineering effect database [4].

3 system achieve a highly condensed summary of the innovation process, through studying human innovation instance, the innovation system is based on that the establishment of the excitation environment of innovative thinking, set conversion condition for innovative thinking, the specification activities of the process, combined with the principle of engineering and technical innovation, control and prediction to achieve a certain degree of innovative thinking. Method of solving the problem using TRIZ is shown in Figure TRIZ Theory Application on Structural Design of Assisted Washinghand Device 3.1. Area Adjustment of Drawing Board using Physical Contradiction At present, the biggest size of the drawing board used at the university is 420mm 297mm. In the drawing, the size of the drawing board sometimes need big, sometimes need to small. This forms a physical contradiction. Physical contradiction is as follows: (1) Big drawing board can realize the drawing of big mechanical drawing sheet. (2) Small drawing board is easier to carry. The core concept of the solving of physical contradiction is the separation of physical contradiction. Separate principle of physical contradiction is as shown in Figure 2. Separate method Space seperate Time seperate Condition seperate System level seperate Figure 2. Separate Principle of Physical Contradiction Space separate principle is used to solve this problem. Step 1: the definition of physical contradiction Parameter: area of drawing board Requirement 1: big area can realize the drawing of big drawing sheet. Requirement 2: small area is easier to carry. Step 2: If we want to realize the ideal condition of technology system, which spaces can realize the different requirement of the parameter? Space 1: the upper spaces Space 2: the lower spaces Srep 3: analyze these two space region, and judge these two space region whether intersect or not? Through the analysis, these two space region don t intersect, so we select the space separate principle to solve this problem. The relation between separate principle and 40 invention principle is as shown in Table 1. 1#inventive principle: Segmentation method 2#inventive principle: Taking out method 3#inventive principle: Local quality method 4#inventive principle: Asymmetry method 7#inventive principle: Nested doll method 13#inventive principle: Do it in reverse method 17#inventive principle: Another dimension method 24#inventive principle: Intermediary method Copyright c 2015 SERSC 399

The Relation between Separate Principle and 40 Invention Principle Separate principle Invention principle Space separate principle 1, 2, 3, 4, 7, 13, 17, 24, 26, 30 Compare with these invention principles, invention principles of 1#, 7#, the integration of 1# and 5# are adopted to solve the contradiction of area and length of stationary object. Scheme 1: Segmentation method Split type drawing board is as shown in Figure 3. Figure 3.

Expanded Structure of Multi-functional Folding Drawing Board Through the analysis and comparison, we select the scheme 3 to solve this problem. 3.2 Angle Adjustment of Drawing Board using Technical Contradiction Aiming to the problem of angle adjustment of drawing board, utilization conveniency and aesthetics of drawing board form a contradiction. Through the contradiction table, we select the inventive 7# and 17# to solve this problem. The angle adjustment structure adopts the ratchet mechanism or worm and gear mechanism. The angle adjustment structure is embedded the inside of drawing board. When we use it, the angle adjustment structure is come put in order to realize the adjustment. 4. Strength Evaluation 4.1. Strength Check for the Supporting Pole on the Upper Board As shown in Figure 6, for load-bearing, the supporting pole linked with worm wheel can be simplified into a 200mm long straight tube, the loading on the bearing face of the tube can be counted as uniformly distributed load.

Evaluate Rigidity of the Supporting Pole From the simplified model, the maximum deformation (deflection) when maximum load is loaded on the supporting pole is, 4 4 5qL max = - = - m = m = -3.2mm (10) EI z From this, the maximum bending deformation of the supporting pole is 3.2mm and it appears at the middle position, satisfies the using requirement. 5. Finite Element Analysis of Key Components After 3D modeling of the multifunctional foldable drawing board, it is necessary to carry out static analysis for the loaded key parts, to detect corresponding mechanical properties of the multifunctional foldable drawing board structure. In the condition of sketchpad loaded, sketchpad deformation will affects the quality of the drawing. This work applied ANSYS/Workbench software to 1mm thickness, 2mm thickness on upper sketchpad and the upper board surface perpendicular to supporting frame for the statics analysis. 5.1 Statics Analysis of Upper Sketchpad with Thickness of 1mm Statics analysis were conducted respectively on upper board when thickness of 1mm, thickness of 1mm with additional stiffeners on surface.
