Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If traditional battery-powered design is used, then power supply is available, but service life is short and requires frequent replacement or recharging
Solution Approach 1:
The insole generates its own electrical energy through friction nanogenerators that convert mechanical energy from walking and running into electrical energy, eliminating the need for external battery replacement or recharging. The system serves itself by continuously generating power during use.
Solution Approach 2:
The patent changes the energy supply parameter from stored chemical energy (batteries) to generated electrical energy through friction-based triboelectric effect, fundamentally altering how the insole obtains and sustains power over time.
2Power
If friction generators are assembled with mechanical parts (cover plate, support column, spring), then power generation function is achieved, but assembly process becomes complex and mechanical structure stability deteriorates
Solution Approach 1:
The patent integrates the friction nanogenerator directly into the insole body structure, merging the power generation function with the insole's mechanical structure. This eliminates separate mechanical components like cover plates, support columns, and springs, resulting in a unified integrated design.
Solution Approach 2:
The patent replaces complex mechanical assembly systems with an integrated fabric-based structure where the friction nanogenerator is embedded within the insole material itself, substituting traditional mechanical components with a more streamlined integrated system.
3Power
If multiple independent friction generators are assembled with mechanical parts, then power generation function is achieved, but mechanical structure stability is poor and fatigue resistance is poor
Solution Approach 1:
The patent combines multiple friction nanogenerators into a unified integrated structure within the insole body, eliminating independent mechanical assemblies. This integration improves structural stability and fatigue resistance by removing weak points associated with separate mechanical components and their connections.
4Ease of manufacture
If friction power-generating shoe body is not integrated, then manufacturing is easier, but assembly process becomes complex and service life shortens
Solution Approach 1:
The patent merges the friction nanogenerator assembly with the insole body into a single integrated unit, eliminating the need for separate assembly steps. This integration maintains manufacturing simplicity while drastically reducing assembly process complexity and improving service life.
