Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light curing apparatuses emit curing light unevenly, resulting in slower curing speeds for the bottom portions of curable objects, which can lead to deformation or warpage during the curing process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional light curing apparatus emits curing light onto side portion only, then device structure is simple, but curing speed of bottom portion is slow causing deformation or warpage
Solution Approach 1:
The patent introduces a bottom light curing module that emits light from the vertical dimension (bottom upward) in addition to the traditional side light curing. This dimensional change allows curing light to reach the bottom portion of the curable object directly, solving the uneven curing problem without requiring complex multi-angle side lighting systems.
Solution Approach 2:
The light curing apparatus is segmented into multiple independent light curing modules: side light curing modules and a bottom light curing module. Each module can be independently controlled and optimized, allowing the bottom module to specifically address bottom portion curing while side modules handle lateral surfaces, thereby improving overall curing uniformity.
2Productivity
If bottom light curing module is added to increase curing speed, then curing uniformity is improved, but device complexity increases
Solution Approach 1:
The bottom light curing module uses the same basic light curing unit structure as the side modules, maintaining component universality. This allows the system to increase curing speed by adding functional modules rather than redesigning the entire system, thereby improving productivity with minimal increase in overall device complexity.
3Manufacturing precision
If carrier rotates to enable bottom light curing coverage, then curing uniformity is improved, but device complexity increases
Solution Approach 1:
The patent introduces a rotating carrier that dynamically changes the position of the curable object during curing. This dynamic rotation ensures that the bottom light curing module can uniformly illuminate the entire bottom surface of the curable object, achieving consistent curing quality. The rotation mechanism is simple and can be driven by basic motors or even manual rotation.
Solution Approach 2:
The rotating carrier design allows the curable object itself to present different surfaces to the light source during rotation, eliminating the need for complex multi-position light sources. The object's own rotation serves the curing function, reducing the complexity of the lighting system while improving curing uniformity.
