Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless signal transmission units are added to enable remote control, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The actuator unit generates its own electrical energy through the movement of its movable element (pedal) to power the wireless signal transmission unit and control unit. This self-powered mechanism eliminates the need for external power sources, batteries, or complex power management systems, thereby improving ease of operation while avoiding additional device complexity from power supply components.
Solution Approach 2:
The patent combines the power generation function directly into the actuator unit by integrating an electrical energy generator that converts mechanical movement into electrical energy. This merged design powers both the wireless transmission and control functions within the same unit, reducing overall system complexity while enabling remote operation.
2Manufacturing precision
If multiple signal generation means are used to control protection unit and generator sequentially, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The control unit is divided into distinct functional components: first signal generation means that activates upon pedal movement to trigger the protection unit, and second signal generation means that activates upon pedal release to trigger the generator. This segmentation enables precise sequential control of different system functions while keeping each signal generation mechanism simple and independent.
Solution Approach 2:
The first signal generation means is designed to activate the protection unit before the generator starts operating. This preliminary action ensures that the protective shield is already in place before any potentially harmful operations begin, achieving precise timing control through预先 activation rather than complex coordinated control.
