Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conductive slip rings are used to transmit power during rotation, then power transmission is achieved, but friction and heat generation occur leading to reduced service life
Solution Approach 1:
The patent replaces the mechanical contact-based conductive slip ring system with a wireless power transmission system using electromagnetic fields. The transmitting device is fixed to the housing while the receiving device is mounted on the rotating framing and shaping mechanism, eliminating mechanical friction and contact wear entirely. This substitution resolves the contradiction by maintaining power transmission capability while dramatically improving reliability and service life.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium to transmit power between the stationary housing and the rotating framing mechanism. The electromagnetic field acts as a non-contact mediator that transfers energy without physical contact, thereby eliminating the friction and heat generation problems associated with traditional conductive slip rings while maintaining continuous power supply during rotation.
2Productivity
If conductive slip rings rotate at high speed, then richer lighting effects are achieved, but excessive heat is generated causing safety accidents
Solution Approach 1:
The patent replaces the mechanical friction-based power transmission system with a wireless electromagnetic power transmission system. This eliminates the heat generation caused by friction during high-speed rotation, allowing the framing mechanism to rotate at higher speeds to create richer lighting effects without the safety risk of excessive heat accumulation.
Solution Approach 2:
The patent converts the limitation of wireless power transmission (lower efficiency at distance) into an advantage by eliminating heat generation entirely. While electromagnetic field strength decreases with distance, the complete elimination of frictional heat allows for safer high-speed operation, and the system compensates for transmission efficiency through optimized coil positioning and resonance frequency matching.
3Use of energy by moving object
If conductive plates are kept in contact for power transmission, then power supply is maintained, but the distance between components is limited increasing cost and complexity
Solution Approach 1:
The patent uses electromagnetic fields as an intermediary to transmit power over larger distances without requiring continuous physical contact between components. The transmitting and receiving electromagnetic coils can be positioned at optimal distances for efficient wireless power transfer, eliminating the need for complex contact maintenance mechanisms and reducing overall system complexity while maintaining reliable power supply.
4Reliability
If rotation angle is limited to prevent wire entanglement, then wire integrity is maintained, but lighting effects are restricted
Solution Approach 1:
The patent replaces the mechanical wire-based power and signal transmission system with wireless electromagnetic transmission. This allows the framing and shaping mechanism to rotate through unlimited angles (360 degrees or more) without wire entanglement, greatly expanding the variety of lighting effects that can be achieved while maintaining reliable power and communication through the wireless electromagnetic field system.
