Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent bulbs or large number of LED light sources are used to light large surfaces, then illumination coverage is improved, but material usage and resource consumption increase
Solution Approach 1:
The lighting system is divided into multiple modular LED strips, each containing a series of LED light sources arranged linearly. These strips can be individually installed and connected to illuminate large surfaces efficiently, reducing material waste compared to using whole fluorescent bulbs or scattered LED fixtures.
Solution Approach 2:
The patent uses thin flexible circuit boards to mount LED light sources, allowing the lighting system to conform to various surface geometries while using minimal material. The flexible PCB substrate enables compact LED strip design that covers large areas without requiring substantial structural support or material volume.
2Stability of the object's composition
If traditional LED assemblies with substantial material for fixing are used, then structural stability is improved, but ease of installation deteriorates
Solution Approach 1:
The lighting system is divided into modular LED strips that can be independently handled and installed. Each strip is a self-contained unit with integrated circuitry and mounting features, allowing installers to work with manageable segments rather than large complex assemblies, thereby improving ease of installation while maintaining stability through proper modular connections.
Solution Approach 2:
The LED strips incorporate self-adhesive mounting features or integrated mounting elements that allow the strips to attach to surfaces without requiring extensive external fixing materials or complex assembly procedures. The strips are designed to be easily mounted by the installer themselves, reducing the need for specialized tools or materials.
3Illumination intensity
If existing LED assemblies are used, then lighting function is provided, but installation time and effort increase
Solution Approach 1:
The LED strips are pre-assembled with circuit boards, LED light sources, and mounting features integrated into ready-to-install modules. Electrical connections and structural elements are prepared in advance during manufacturing, so that during installation, the strips can be quickly mounted and connected without requiring time-consuming assembly steps on-site.
Solution Approach 2:
The patent combines multiple functions into the LED strip module itself: lighting emission, electrical connection pathways, and mounting attachment are all integrated into a single modular unit. This consolidation eliminates the need for separate installation steps for each function, significantly reducing total installation time and effort compared to traditional assemblies requiring separate components.
4Ease of manufacture
If existing LED assemblies with limited installation contingencies are used, then manufacturing simplicity is maintained, but adaptability to different installation methods deteriorates
Solution Approach 1:
The LED strip module is designed with universal mounting features that accommodate multiple installation methods and surface types. The strips can be mounted on walls, ceilings, or other surfaces using various techniques (adhesive, mechanical fastening, surface mounting) while maintaining the same basic manufacturing process, thereby providing installation flexibility without complicating manufacturing.
