Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If LED strip is adhered to housing using adhesive, then LED strip is securely fixed in place, but residual adhesive remains after removal making it difficult to install new LED strip
Solution Approach 1:
The patent extracts the adhesive from the attachment system and replaces it with a magnetic coupling mechanism. The LED strip is attached to a ferromagnetic strip that is held against the housing by magnets, eliminating adhesive residue issues while maintaining secure attachment during operation and enabling easy removal for replacement.
Solution Approach 2:
The patent replaces the chemical bonding mechanism (adhesive) with a magnetic field-based mechanical system. The magnetic attraction between magnets in the housing and the ferromagnetic strip provides secure attachment, while the absence of adhesive allows for clean removal and replacement of the LED strip.
2Volume of moving object
If housing is made very thin to reduce size, then device compactness is improved, but it becomes difficult to remove LED strip from within housing
Solution Approach 1:
The patent segments the lighting device into distinct modular components: the housing, the ferromagnetic strip, and the LED strip. This segmentation allows the LED strip to be independently removed from the housing by first detaching the ferromagnetic strip via magnetic release, facilitating easy replacement even in thin housings.
Solution Approach 2:
The patent extracts the ferromagnetic strip as a separate intermediate component between the housing and LED strip. This intermediate layer can be magnetically detached from the housing, allowing the LED strip to be removed without requiring access to the entire housing interior, making replacement feasible in thin housing designs.
3Ease of manufacture
If LED strip is permanently installed in housing, then installation simplicity is improved, but future replacement and maintenance become difficult
Solution Approach 1:
The patent introduces dynamic reversibility to the attachment system through magnetic coupling. The ferromagnetic strip can be easily detached from the magnets by overcoming the magnetic force, allowing the LED strip to be removed and replaced. This dynamic attachment mechanism maintains installation simplicity while enabling efficient future maintenance.
Solution Approach 2:
The patent facilitates the discarding of failed LED strips and recovery/reuse of functional components. The magnetic attachment system allows for easy removal of defective LED strips while preserving the housing, ferromagnetic strip, and other components for continued use or replacement with new LED strips.
