Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mechanical control methods (buttons or cables) are used to adjust the shock-absorbing device, then the device can be adjusted according to practical needs, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent replaces conventional mechanical control systems (buttons, cables, levers) with an electronic control system comprising a DC power unit, driving unit with motor, controller, and communication module. This substitution eliminates complex mechanical linkages while maintaining the ability to adjust shock-absorbing characteristics, thereby reducing structural complexity and manufacturing cost while preserving adaptability
Solution Approach 2:
The patent introduces a communication module as an intermediary between the user interface and the motor-driven adjustment mechanism. This intermediary enables wireless or cabled communication to transmit control signals, eliminating the need for direct mechanical connection between control elements and adjustment mechanisms, thus simplifying the overall structure
2Adaptability or versatility
If conventional mechanical control methods are used, then adjustment is possible, but user convenience decreases due to complex operation
Solution Approach 1:
The patent replaces manual mechanical operation with electronic control through a communication module that accepts wireless or cabled signals. Users can adjust shock-absorbing parameters remotely using electronic interfaces rather than manipulating mechanical components, significantly improving ease of operation while maintaining full adjustability
Solution Approach 2:
The controller automatically processes control signals and drives the motor to adjust the spring rate adjustment device without requiring manual intervention in the mechanical adjustment process. The system serves itself by converting electronic commands into mechanical adjustments automatically, enhancing user convenience
