Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If identification information is provided through labels, then the device structure is simple, but the labels are easily counterfeited, contaminated or damaged by external environment
Solution Approach 1:
The patent replaces the mechanical label system with an optical display system. Instead of using physical labels that can be contaminated or damaged, the invention uses light-emitting units (OLEDs) driven by induction coils to display identification information optically, making it resistant to environmental factors.
Solution Approach 2:
The patent introduces induction coils and rectifying circuitry as intermediary components between the power source and light-emitting units. These intermediaries enable wireless power transfer and signal rectification, allowing the display of identification information without physical contact, thus preventing contamination.
2Ease of operation
If labels are used for identification, then the device complexity is low, but user identification convenience is reduced
Solution Approach 1:
The patent replaces static mechanical labels with dynamic optical displays. The light-emitting units can actively display identification information that is easily readable by users, improving identification convenience despite the increased complexity of the underlying module structure.
3Reliability
If induction coils and rectifying circuitry are added to the substrate, then identification information reliability is improved through light emission, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the substrate module: wireless power reception through induction coils, signal rectification through rectifying circuitry, and identification information display through light-emitting units. This multi-functionality justifies the increased complexity by providing reliable, contamination-resistant identification.
Solution Approach 2:
The patent merges the power reception system (induction coils) and the display system (light-emitting units) into a single integrated substrate module. The induction coils and rectifying circuitry are directly coupled to the light-emitting units, combining multiple functions into one compact structure.
