Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED lights use built-in filaments for connection, then the structure is simple, but color variation is limited and design shapes are restricted
Solution Approach 1:
The LED light string is divided into multiple independent LED light units, each containing its own light-emitting portion with specific geometric shapes (circles, squares, triangles, etc.). This segmentation allows each unit to be individually designed with different shapes and colors while maintaining simple filament-based connections, thus achieving both structural simplicity and design versatility.
2Shape
If shaped filaments with built-in power supply and control components are used, then design shapes are achieved, but installation becomes cumbersome and scene continuity is difficult
Solution Approach 1:
The power supply and control components are extracted from individual LED light units and consolidated into a shared power cord with control circuitry. Each LED light unit retains only the essential light-emitting portion with simple filament connections, eliminating the need for individual power supplies and control components at each unit, thus achieving design shapes while simplifying installation and ensuring scene continuity.
Solution Approach 2:
The power cord serves multiple functions: it provides electrical connection between LED light units, supplies power to all units, and incorporates control circuitry for dynamic display effects. This multi-functionality eliminates the need for separate power supplies and control components at each LED unit, making installation convenient while maintaining design flexibility.
3Adaptability or versatility
If individual LED lights with built-in power supply are used, then design flexibility is achieved, but installation is cumbersome and scene integrity is compromised
Solution Approach 1:
Multiple functional components (power supply, control circuitry, connection pathways) are merged into a centralized power cord system that serves all LED light units. Each LED unit maintains design flexibility through its geometric-shaped light-emitting portion, while the merged power cord system simplifies installation by providing unified power and control, ensuring scene integrity through continuous connectivity.
