Engineering Contradiction Analysis
1Illumination intensity
If multiple planar light sources are used to achieve 360-degree illumination, then illumination coverage is improved, but the number of assembling processes increases and gaps between components are created
Solution Approach 1:
The patent merges multiple planar light sources into a single three-dimensional light source structure. The case is formed by bending a contiguous surface to create multiple planar sections that function as light sources, eliminating the need for separate assembly of multiple independent light source components while maintaining 360-degree illumination coverage.
Solution Approach 2:
The patent employs a three-dimensional light source with a spherical or polyhedral outer shape formed by bending a contiguous surface. This curved three-dimensional structure replaces multiple flat planar light sources, allowing 360-degree illumination while reducing component count and assembly complexity through the continuous bent geometry.
2Illumination intensity
If multiple components are assembled to achieve 360-degree illumination, then illumination functionality is improved, but dust-proofing and moisture barrier properties deteriorate due to gaps between components
Solution Approach 1:
The patent combines multiple light-emitting functions into a single integrated three-dimensional light source structure with a continuous bent case. This merging eliminates gaps between separate components, creating a sealed structure that maintains dust-proofing and moisture barrier properties while achieving 360-degree illumination functionality.
Solution Approach 2:
The patent uses a three-dimensional light source with a spherical or polyhedral outer shape formed by bending a contiguous surface. This continuous curved geometry eliminates gaps between components, providing a sealed structure that protects internal components from dust and moisture while maintaining full illumination functionality.
3Device complexity
If a three-dimensional light source with bent portions is used, then the number of assembling processes is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies that the three-dimensional light source has a spherical or polyhedral outer shape formed by bending a contiguous surface. This geometric specification provides clear manufacturing guidelines for creating the bent portions, balancing the reduction in assembly processes with achievable manufacturing precision requirements through standard forming techniques.

AI summary
A lighting device that is capable of illuminating in all directions includes: a case that includes a plurality of wall portions each including a face in a polygonal shape; a plurality of light-emitting elements that are provided in the plurality of wall portions and emit light toward outside of the lighting device; and a controller that controls the plurality of light-emitting elements separately. The case is of an outer shape that is spherical or polyhedral. The case includes bent portions that are bent in the outer shape of the case. The bent portions constitute at least three sides of the outer shape of the case.
