Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting devices for automobile wheels generate electrical energy through torque but often result in advertisement members being tilted due to reverse magnetic fields during electricity generation, leading to ineffective display of advertisement contents.
Innovation Solution
A light emitting device comprising a fixed member, rotor, circuit board, stator, light emitting members, and an idle rotation support body, where a weight maintains the circuit board's position and an advertisement member is secured to prevent tilting, with a light guide plate ensuring uniform illumination and preventing dark spots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If electrical energy is generated through torque using a magnet and coil in the wheel, then the advertisement member can be illuminated, but the advertisement member becomes tilted due to reverse magnetic field
Solution Approach 1:
A counterweight is added to the rotating shaft to balance the reverse magnetic field force generated during electricity generation. The counterweight creates an opposing force that prevents the advertisement member from tilting, allowing the system to maintain stable posture while generating electrical energy for illumination.
2Stability of the object's composition
If an anti-rotation wing is used to maintain fixed state of stator, then rotation is prevented, but manufacturing process becomes complicated and cost increases
Solution Approach 1:
The complex anti-rotation wing structure is removed and replaced with a simpler counterweight mechanism. The counterweight achieves the same functional goal of preventing unwanted rotation while significantly simplifying the manufacturing process and reducing production costs.
3Ease of operation
If advertisement member is mounted on rotating shaft, then it rotates with the wheel, but it tilts due to reverse magnetic field during electricity generation
Solution Approach 1:
The counterweight compensates for the tilting force generated during electricity generation, allowing the advertisement member to remain mounted on the rotating shaft in a simple manner while maintaining stable posture throughout rotation.
