Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single light source and battery are used in the casing, then the device structure is simple, but the lighting intensity is low and the volume occupancy is large
Solution Approach 1:
The patent divides the lighting system into multiple independent light sources (LED beads) distributed around the inner wall of the spherical casing, rather than using a single centralized light source. This segmentation allows each LED to contribute to the overall illumination, significantly increasing total lighting intensity while maintaining a compact structure that fits within the spherical casing.
2Volume of stationary object
If the volume of the light source is reduced to fit more components, then the device volume is optimized, but the lighting intensity decreases
Solution Approach 1:
The patent transitions from a single-point light source configuration to a distributed spatial arrangement of multiple LED beads along the inner spherical surface. This dimensional redistribution allows the light-emitting elements to occupy the available volume efficiently while collectively providing high illumination intensity through their combined output.
3Volume of stationary object
If the volume of the battery is reduced to accommodate more components, then the device volume is optimized, but the durability and power supply capacity decrease
Solution Approach 1:
The battery is nested within the spherical casing structure, with the light sources arranged around it. This nesting arrangement allows the battery to occupy the central volume efficiently while the light sources are positioned in the surrounding space, maximizing the use of available volume without compromising battery capacity or durability.
4Illumination intensity
If multiple light sources are used to achieve uniform illumination, then the lighting uniformity improves, but the device complexity and difficulty of controlling color temperature increases
Solution Approach 1:
The patent employs multiple LED beads with potentially different color temperatures distributed around the spherical casing, allowing different regions of the sphere to emit light with locally optimized characteristics. This enables uniform overall illumination while maintaining flexibility in controlling the color temperature of individual light sources to achieve desired lighting effects.
