Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple springs and dampers are used to increase similarity with mechanical booster, then braking sense is improved, but device complexity and number of parts increase
Solution Approach 1:
The patent combines multiple spring elements into a single integrated elastic member (300) that provides both the first elastic force and second elastic force functions. This merging of multiple components into one reduces structural complexity while maintaining the braking sense similarity to mechanical boosters.
Solution Approach 2:
The elastic member (300) serves multiple functions: it acts as both the first elastic member supporting the piston body and the second elastic member supporting the piston rod, replacing what would traditionally require separate springs and dampers. This multi-functionality reduces the number of parts while achieving the desired braking sensation.
2Reliability
If conventional pedal simulator structure is used, then braking sense is provided, but repair and replacement costs increase due to complexity
Solution Approach 1:
By integrating multiple elastic support functions into a single elastic member (300), the patent reduces the number of replaceable components. This simplification directly lowers repair and replacement costs while maintaining the essential braking sense provision function.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate components (such as separate return springs and complex mounting mechanisms) from the conventional design, retaining only the essential elastic support function through a simplified elastic member, thereby reducing maintenance complexity and cost.
3Reliability
If conventional pedal simulator design is used, then braking sense is achieved, but adaptability to different pedal types is limited
Solution Approach 1:
The simplified elastic member (300) design with its dual support function creates a universal pedal simulator structure that can be adapted to different pedal types (accelerator, brake, clutch) without requiring type-specific components, thereby improving versatility while maintaining braking sense generation.
Solution Approach 2:
The patent segments the pedal simulator into modular components (housing part, piston part, elastic member) that can be independently configured for different pedal applications, enhancing adaptability across various pedal types while preserving the core braking sense generation capability.
