Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional screen mounted lamps are designed to provide illumination, then illumination function is achieved, but volume and weight become large
Solution Approach 1:
The patent merges the first and second light-emitting elements onto a single substrate, integrating multiple illumination functions into one compact structure. This consolidation reduces the overall device volume and weight while maintaining the capability to provide both desktop illumination and screen backlighting functions
Solution Approach 2:
The illumination device achieves multi-functionality by using one substrate to support multiple light-emitting elements that can illuminate in different directions. The device can simultaneously provide desktop illumination through the first light-emitting element and screen backlighting through the second light-emitting element, eliminating the need for separate devices
2Adaptability or versatility
If conventional screen mounted lamps provide multiple illumination directions, then usage scenarios increase, but structure becomes complex
Solution Approach 1:
Multiple light-emitting elements are integrated onto a single substrate with unified electrical connections, merging what would traditionally require separate devices into one compact unit. This integration maintains diverse illumination capabilities while significantly reducing structural complexity
Solution Approach 2:
The patent arranges light-emitting elements in different spatial orientations on the substrate, with first light-emitting elements facing downward for desktop illumination and second light-emitting elements facing forward for screen backlighting. This spatial arrangement enables multiple illumination directions from a single planar substrate
3Illumination intensity
If conventional screen mounted lamps use multiple substrates for different light-emitting elements, then illumination functionality is enhanced, but assembly complexity increases
Solution Approach 1:
The patent consolidates multiple light-emitting elements onto a single substrate, eliminating the need for separate substrates and their associated mounting structures. This merger dramatically simplifies assembly operations while preserving all illumination functionalities, making the device more suitable for mass production
Solution Approach 2:
A single substrate is designed to support multiple light-emitting elements with different orientations and functions, making the substrate itself a multi-functional platform. This universal substrate design reduces the total component count and simplifies the manufacturing process
4Ease of manufacture
If conventional screen mounted lamps are designed with simple structure, then manufacturing is easier, but usage scenarios are limited
Solution Approach 1:
The patent designs a universal substrate that can accommodate multiple light-emitting elements in various configurations, enabling the device to adapt to different usage scenarios. The substrate serves as a platform that supports both desktop illumination and screen backlighting functions within a single simple structure
Solution Approach 2:
The patent utilizes vertical spatial arrangement of light-emitting elements on the substrate, with elements oriented in different directions (downward for desktop, forward for screen). This dimensional arrangement enables multiple usage scenarios without complicating the overall structure
