Innovation Solution
An illumination device comprising multiple flat light guide plate units with a light source, cover, and case, attached to a base with detachable sections and circuit boards, allowing for independent presentation, easy assembly/disassembly, and replacement of defective units, along with bent-shaped units for three-dimensional configurations and cost reduction by sharing light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional illumination devices are used in bright and brilliant spaces, then the device can provide basic illumination, but the device lacks appeal and cannot give sufficient impact to players
Solution Approach 1:
The illumination device is divided into multiple modular units that can be independently configured and arranged. Each unit contains its own light source and light guide plate, allowing flexible arrangement patterns and designs. This segmentation enables the device to adapt to different spatial requirements and create varied illumination effects in bright and brilliant spaces.
Solution Approach 2:
The patent introduces three-dimensional arrangement of light guide plates in addition to traditional two-dimensional planar arrangements. By stacking light guide plates at different heights and angles, the device creates multi-layered illumination patterns that add visual depth and impact, transforming conventional flat illumination into dynamic three-dimensional light displays.
2Ease of repair
If the illumination device uses fixed integrated structure, then the device can maintain structural simplicity, but the maintainability deteriorates when defects occur
Solution Approach 1:
The device is segmented into independent modular units, each with its own light source, light guide plate, and housing. When a defect occurs, only the affected module needs to be removed and replaced, not the entire device. This segmentation dramatically improves maintainability while keeping each individual module structurally simple.
Solution Approach 2:
The patent implements detachable and replaceable modules that can be dynamically assembled and disassembled. The standardized connection interfaces allow for easy installation and removal of modules, enabling flexible maintenance operations without requiring complex disassembly procedures or specialized tools.
3Manufacturing precision
If the light guide plate units are arranged to cover the entire attachment surface, then uniform illumination is achieved, but the device complexity increases due to multiple units
Solution Approach 1:
The illumination surface is divided into multiple standardized modular units that can be arranged in grid patterns. Each unit produces uniform illumination on its portion of the surface, and the modular design allows for easy scaling to cover larger areas while maintaining overall uniformity through consistent unit specifications and connection methods.
