Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high current LEDs are used to achieve bright light sources, then illumination intensity is improved, but panel thickness increases due to larger spacing between LEDs and diffuser
Solution Approach 1:
The patent divides the lighting system into modular light panels that can be independently positioned and adjusted. Each panel contains individual LEDs that can be spaced closer together, eliminating the need for large diffusion distances while maintaining bright illumination. The modular structure allows each segment to function independently at optimal spacing.
Solution Approach 2:
The patent transitions from a single-plane LED arrangement to a three-dimensional configuration where LEDs are positioned at multiple depths and angles relative to the panel surface. This spatial redistribution allows bright LEDs to be closer to the panel while still achieving uniform illumination through strategic positioning in multiple dimensions.
2Illumination intensity
If more diffusion is used to achieve homogeneous luminance, then illumination uniformity is improved, but system efficiency decreases
Solution Approach 1:
The patent applies different optical properties to different regions of the lighting system. Instead of uniform diffusion across the entire panel, specific local areas have tailored optical characteristics that redirect light precisely where needed. This localized light management achieves homogeneous luminance while minimizing overall energy loss.
Solution Approach 2:
The patent introduces reflective surfaces and optical guides as intermediary elements between the LEDs and the panel surface. These intermediaries redirect and distribute light more efficiently, reducing the need for excessive diffusion while maintaining uniform illumination and preserving system efficiency.
3Temperature
If large heat sinks are used to manage thermal buildup, then temperature control is improved, but device complexity and space requirements increase
Solution Approach 1:
The patent integrates thermal management functions directly into the existing structural components of the lighting system. Heat sinks are combined with mounting frames, and thermal pathways are incorporated into the panel structure itself, eliminating separate thermal management subsystems and reducing overall complexity.
Solution Approach 2:
The patent designs structural components to serve multiple functions simultaneously. Mounting frames provide both mechanical support and thermal conduction, while panel structures offer both light diffusion and heat dissipation pathways. This multi-functionality reduces the number of dedicated thermal management components needed.
4Adaptability or versatility
If custom sizing is implemented to fit particular locations, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The patent divides the lighting system into standardized modular panels that can be configured in various combinations to fit different installation spaces. Instead of custom-building each installation, the same standardized modules are assembled in different quantities and arrangements, maintaining manufacturing efficiency while achieving adaptability.
Solution Approach 2:
The patent creates a flexible configuration system where standardized modules can be dynamically arranged to suit different spatial requirements. The modular design allows the same components to be adapted to various installations through reconfiguration rather than custom manufacturing, balancing versatility with manufacturing simplicity.
