Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple optical covers are used to meet different regulatory and lighting requirements, then the lighting device can satisfy diverse regional requirements, but the development period is prolonged and maintenance costs increase
Solution Approach 1:
The patent divides the optical cover into two separate functional components: a lens that produces a first light shape and an optical cover that produces a second light shape. By segmenting the optical system into modular components with distinct functions, the patent enables flexible combination to meet different regional requirements without developing entirely new optical covers for each application.
Solution Approach 2:
The patent creates a universal optical system where a single lens design can be combined with different optical cover configurations to satisfy multiple regional lighting requirements. The lens produces a base light shape that can be modified by the optical cover to achieve various final light distributions, making the system adaptable to different standards without requiring complete redesigns.
2Adaptability or versatility
If multiple optical covers are used to meet different regulatory and lighting requirements, then the lighting device can satisfy diverse regional requirements, but maintenance costs increase
Solution Approach 1:
By segmenting the optical system into a reusable lens and interchangeable optical cover components, the patent enables selective replacement of only the optical cover when maintenance is needed, rather than replacing entire assemblies. This reduces maintenance costs while maintaining the ability to meet different regional requirements through component selection.
Solution Approach 2:
The universal lens design can be paired with different optical covers to meet various regional standards, reducing the total number of unique components that need to be maintained. A single lens can serve multiple applications by combining with different optical covers, thereby reducing overall maintenance complexity and costs.
3Device complexity
If traditional lighting device design uses light source on optical cover to produce required light shape, then the design is simple, but it requires several kinds or even dozen kinds of optical covers
Solution Approach 1:
The patent segments the optical design into two independent components: a lens with specific optical properties and an optical cover with complementary functions. This segmentation allows each component to be optimized independently, reducing the need for multiple complete optical cover designs while still achieving the required light shapes for different applications.
Solution Approach 2:
The patent merges the functions of light shaping and light distribution by combining a lens (for producing the first light shape) with an optical cover (for producing the second light shape). This combination approach reduces the total number of unique optical cover designs needed, as the lens provides a consistent base function that can be adapted through different optical cover configurations.

Function Achieved in This Case
This configuration enables the production of desired light shapes while significantly reducing the number of optical cover designs, thereby shortening development times and lowering maintenance costs.
Implementation Method 1
The lens has a first light-incident surface, a first light-emitting surface opposite to the first light-incident surface... One of the lens and the optical cover produces a first light shape that is rotationally symmetric or non-rotationally symmetric
Implementation Method 2
The optical cover covers the lens and has a second light-incident surface and a second light-emitting surface opposite to the second light-incident surface... the other of the lens and the optical cover produces a second light shape that is rotationally symmetric

AI summary
A light distribution module configured to control a light distribution of a light source is provided. The light distribution module includes a lens and an optical cover. The lens has a first light-incident surface, a first light-emitting surface opposite to the first light-incident surface, and an accommodating recess located at a side of the first light-incident surface, wherein the accommodating recess is configured to contain the light source. The optical cover covers the lens and has a second light-incident surface and a second light-emitting surface opposite to the second light-incident surface, wherein the second light-incident surface is located between the first light-emitting surface and the second light-emitting surface, and the second light-incident surface has a plurality of sub-curved surfaces. Boundaries between adjacent sub-curved surfaces are bent-shaped with respect to the adjacent sub-curved surfaces.
