Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If electromagnetic rotary shock absorbers use traditional non-conductive rotor designs, then they can maintain simple structure, but they cannot efficiently harvest energy or provide active control
Solution Approach 1:
The patent combines the rotor with conductive elements (conductive disc or drum) and directly couples them with the electric control circuit through conductive contact. This merging of previously separate components (rotor, energy harvesting mechanism, and control circuit) into an integrated assembly enables efficient energy harvesting while maintaining a compact structure, resolving the contradiction between energy harvesting efficiency and structural complexity
Solution Approach 2:
The rotor is designed to serve multiple functions simultaneously: it generates currents in the conductive disc/drum for energy harvesting, provides active control through conductive contact with the control circuit, and maintains the mechanical rotation function. This multi-functionality allows the same component to address both energy harvesting and control needs without proportionally increasing complexity
2Adaptability or versatility
If the shock absorber provides both braking and propulsive effects through current generation, then it can dynamically adjust operational characteristics, but it requires integration with electric control circuits
Solution Approach 1:
The control circuit is directly integrated with the rotor through conductive contact, merging the control system with the mechanical rotation system. This direct integration enables the shock absorber to dynamically adjust its operational characteristics (braking and propulsive effects) by controlling the currents generated in the conductive disc or drum, while avoiding the need for separate, complex control wiring and components
3Use of energy by moving object
If the rotor is in conductive contact with the control circuit, then energy harvesting and active control are enabled, but manufacturing precision requirements increase
Solution Approach 1:
The conductive contact between the rotor and control circuit is designed and prepared in advance during manufacturing, with pre-established conductive pathways and contact points. This preliminary action ensures that the conductive contact is properly established before operation, reducing the need for high precision during dynamic operation and simplifying manufacturing requirements while still enabling effective energy harvesting and control
