Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If piezoelectric ceramics are used to convert mechanical deformation to electrical energy, then power generation is achieved, but the deformation range is limited and collection efficiency is extremely low
Solution Approach 1:
The patent divides the energy storage function into multiple spring components (first spring energy storage component and second spring energy storage component), each capable of independent deformation and energy storage. This segmentation allows the system to accumulate energy from multiple deformation cycles rather than relying on a single limited deformation event, thereby improving overall energy collection efficiency.
Solution Approach 2:
The patent introduces a dynamic switching mechanism through the one-way limiter that automatically selects which spring energy storage component to release based on real-time energy levels. This dynamic adjustment optimizes the energy release process, ensuring that the spring with sufficient energy is always the one being released to drive the generator, thus maintaining high productivity throughout operation.
2Productivity
If piezoelectric ceramics are used for power generation, then electrical energy is generated, but the cost of piezoelectric ceramics is very high
Solution Approach 1:
The patent replaces expensive piezoelectric ceramics with mechanical spring components that are significantly cheaper to manufacture. The springs serve as disposable or reusable mechanical energy storage elements that can be replaced at low cost, eliminating the need for costly piezoelectric materials while maintaining power generation capability through the generator.
Solution Approach 2:
The patent substitutes the piezoelectric effect (converting mechanical deformation directly to electrical energy) with a mechanical energy storage and release system. Instead of relying on piezoelectric ceramics to generate electricity during deformation, the system uses springs to store mechanical energy and then releases it to drive a generator, replacing the piezoelectric mechanism with a mechanical-to-mechanical-to-electrical conversion path.
3Reliability
If mechanical limiting structure is used to restrict pedal panel descent, then piezoelectric ceramic deformation is controlled within rated range, but effective displacement distance is very small
Solution Approach 1:
The patent replaces the static mechanical limiting structure with a dynamic energy-based control mechanism. The one-way limiter and spring energy storage components dynamically adjust the system's behavior based on energy accumulation levels, allowing the pedal panel to travel further distances to accumulate sufficient energy in the springs before releasing it, thus increasing displacement distance while maintaining reliable control.
Solution Approach 2:
The patent implements preliminary energy storage by winding up the spring energy storage components during the pedal depression phase. This preliminary action accumulates energy over a longer displacement distance, allowing the system to prepare sufficient energy before the power generation phase, thereby decoupling the displacement distance from the strict deformation limits of piezoelectric ceramics.
4Device complexity
If piezoelectric ceramics are used with fixed mounting structure, then structural simplicity is maintained, but energy collection efficiency is extremely low
Solution Approach 1:
The patent segments the energy storage and release functions into separate spring energy storage components and a one-way limiter mechanism. This segmentation, while adding some structural elements, creates a more efficient energy collection system where each component has a dedicated function, improving overall productivity despite increased complexity compared to simple piezoelectric mounting.
Solution Approach 2:
The patent changes the fundamental operating parameters of the system by replacing piezoelectric materials with mechanical springs and a generator. This parameter change from direct piezoelectric conversion to mechanical energy storage and electromagnetic conversion dramatically improves energy collection efficiency, justifying the increase in device complexity.
