TDP role in developing a new product (design) TDP steps identified product issues and was influential during communication between the design team and customer Gating Requirements Concept Feasibility Prototype Pilot Production Specifications Draft Target specifications Establish specifications/ acceptance criteria Specifications in place Specifications fully documented Template Includes 18 Gating Requirements Will be reviewed in more detail at M2M
TDP Case Study: Product, MEMS Force Sensor Production sensor shown Silicon piezoresistors create full Wheatstone bridge Stress reduction component (SRC) reduces sensor error by mitigating parasitic loads from mounting Microfused MEMS Gages Sensor Body Pivots as a Joy Stick SRC - O-rings Top and Bottom Of Disc
TDP Case Study: Application, MEMS Force Sensor 5% Females and teens meeting weight limit get normal force airbag Children get low force deployment and infants get no airbag Sensors in passenger seat structure measure weight of occupant This information is used to activate (full or reduced force) or deactivate the airbag 4 Sensors in Seat Structure

TDP Case Study: Product Issue Resulted in Redesign during Prototype Stage Original design in prototype stage could not meet sensor accuracy or drift specifications provided by the customer This was highlighted in the TDP with DFMEA, validation and gaps to specification discussions with customer Stress reduction component (SRC) was added to potentially resolve the issue Customer was resistant to adding elastomer to safety critical structure Original Prototype O-rings Prototype with SRC Added Sensor Mechanical Stop Seat Structure SRC Nut
TDP Case Study: The Issue and Impact Identified in DFMEA Issue identified in DFMEA with high RPN number with recommended action of SRC (stress reduction component) Item / Process Function Potential Failure Mode Potential Effect(s) of Failure S e v Potential Cause(s)/ Mechanism(s) of Failure O c c u r Current Design Controls Prevention Current Design Controls Detection D e t e c R.

TDP Case Study: The Issue Identified in Gaps to Specification Initial Accuracy Drift over Life Thermal Shock Vibration Time at Temperature Low Speed Crash High Speed Crash Moment Sensitivity Fore-Aft Skew Test Not Capable to Specification Marginal to Specification Capable to Specification
TDP Case Study: The Impact Without the SRC, the sensor would not have met the accuracy requirements and the customer would not be able to properly classify occupants Without proper occupant classification the customer system would not properly deploy airbags per FMVSS requirements Not meeting FMVSS requirements results in discipline from the federal government (i.e. fines, cannot ship product, etc.) TDP actions, DFMEA, validation and gaps to specification influenced customer to make design change
TDP Case Study: Product Solution The SRC (stress reduction component) was integrated internal to the product per the new customer requirement and resulted in a 3X improvement in performance The sensor met all of the validation requirements from the customer Summary: Customer system met FMVSS requirements, vehicle passengers obtained improved protection during a crash and the product launched on-time Sensor Body Pivots as a Joy Stick SRC - O-rings Top and Bottom Of Disc
