Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional incandescent and fluorescent lighting is used, then light distribution is achieved, but energy consumption is high and environmental impact is negative
Solution Approach 1:
The luminaire is divided into multiple discrete optical cells, each containing an LED module and optical elements. This modular segmentation allows for efficient LED-based lighting while simplifying manufacturing and assembly processes through standardized reusable components.
2Use of energy by moving object
If LED light sources are used, then energy efficiency is improved, but heat dissipation becomes a key problem due to concentrated heat output
Solution Approach 1:
By segmenting the luminaire into multiple optical cells with distributed LED modules, the heat generation is spread across multiple locations rather than concentrated in a single area, facilitating more effective heat dissipation through the luminaire structure.
Solution Approach 2:
The patent introduces air gaps between optical cells and the mounting surface, utilizing the third dimension (vertical spacing) to create convection channels for heat removal, transforming a two-dimensional heat dissipation problem into a three-dimensional solution.
3Use of energy by moving object
If LED light sources are used, then energy efficiency is improved, but the blinding effect occurs due to small light-emitting area
Solution Approach 1:
Optical elements such as diffusers and lenses are introduced as intermediary components between the LED light source and the viewer. These intermediaries redistribute the concentrated light from the small LED emitting area into a broader, more comfortable light distribution that maintains efficiency while eliminating the blinding effect.
4Adaptability or versatility
If modular optical cells are used, then versatility and flexibility are improved, but device complexity increases due to multiple discrete components
Solution Approach 1:
The luminaire is segmented into standardized optical cells that can be independently manufactured and then assembled in various configurations. This segmentation increases versatility while managing complexity through standardization of the modular units.
Solution Approach 2:
The optical cells are designed as universal modular units that can serve multiple functions and be arranged in different patterns to create various luminaire designs, reducing the need for multiple specialized components and simplifying the overall system.
