Innovation Solution
A power generating device using electromagnetic induction, comprising a first shell, sensor module, second shell, and magnetic module, where external force applied to the device induces a current in the induction coil, eliminating the need for mercury batteries and providing a restoring force through magnetic attraction, suitable for integration into shoe pads or ground pads to power LED lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mercury batteries are used in self-luminous devices, then the devices can provide continuous power for LED lighting, but the devices cause environmental pollution and are prone to current leakage and damage
Solution Approach 1:
The patent extracts and removes the harmful mercury battery component from the self-luminous device, replacing it with an electromagnetic power generation system that uses magnetic elements and induction coils to generate electricity through user motion, thereby eliminating environmental pollution while maintaining device reliability
Solution Approach 2:
The device generates its own power through the user's walking motion via electromagnetic induction, eliminating the need for external batteries. The magnetic elements and induction coils work together to convert mechanical energy from user movement into electrical energy, making the device self-sufficient and environmentally friendly
2Reliability
If thin-type batteries are used in self-luminous devices, then the devices can be powered, but high-grade waterproofing equipment is needed to prevent current leakage and damage
Solution Approach 1:
The patent removes the battery component entirely and replaces it with an electromagnetic generation system consisting of magnetic elements and induction coils. This extraction eliminates the need for waterproofing structures while maintaining device reliability through motion-based power generation
Solution Approach 2:
The patent replaces the chemical energy storage system (batteries requiring waterproofing) with a mechanical-to-electrical energy conversion system using electromagnetic induction. The magnetic elements and induction coils convert user motion directly into electricity, eliminating the need for complex waterproofing equipment
3Object-generated harmful factors
If electromagnetic induction is used to generate power through user action, then mercury batteries and high-grade waterproofing are eliminated, but the device structure becomes more complex with multiple magnetic elements and induction coils
Solution Approach 1:
The patent merges multiple functional components into an integrated electromagnetic generation system where magnetic elements, induction coils, and slide gaps work together as a unified mechanism. This consolidation achieves power generation through user motion while managing structural complexity through functional integration
