Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an electronic throttle body system is used, then throttle control precision and engine performance are improved, but compatibility with Bowden cable-based devices is lost
Solution Approach 1:
A remote throttle control relay is introduced as an intermediary device that receives mechanical input from a Bowden cable and converts it into electronic control signals for the electronic throttle body. This mediator enables compatibility between legacy mechanical control systems and modern electronic throttle systems without compromising the precision of the electronic throttle control.
2Adaptability or versatility
If a Bowden cable mechanical linkage is used, then compatibility with various devices is maintained, but throttle control precision and engine performance are reduced
Solution Approach 1:
The patent replaces the mechanical Bowden cable linkage system with an electronic control system. A remote throttle control relay converts mechanical cable movement into electronic signals that precisely control the electronic throttle body, substituting the imprecise mechanical system with a precise electronic system while maintaining compatibility through the relay interface.
3Adaptability or versatility
If additional modifications are made to achieve compatibility, then Bowden cable compatibility is restored, but device complexity and modification requirements increase
Solution Approach 1:
The remote throttle control relay is designed as a universal interface device that can accommodate various Bowden cable configurations while outputting standardized electronic signals compatible with electronic throttle bodies. This multi-functional design enables broad compatibility without requiring complex or device-specific modifications, simplifying the integration process.
