Exposure Device Cured Body Surface Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exposure devices require complex and costly machining of aluminum die-cast bodies for precise surface flatness, leading to increased manufacturing costs.
Innovation Solution
The use of a cured body formed by curing a deformable material on a support member, which simplifies the manufacturing process and reduces costs by eliminating the need for intricate machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a die-cast body with machined board contact surface is used, then manufacturing precision of surface flatness is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces the expensive die-cast body with a inexpensive molded resin body that achieves the required surface flatness through the molding process itself, eliminating the need for costly machining operations while maintaining functional precision
Solution Approach 2:
The patent changes the material from metal die-cast to molded resin, and changes the surface formation method from post-machining to mold-integrated surface formation, thereby reducing manufacturing cost while achieving required flatness
2Manufacturing precision
If complex machining is performed on die-cast body, then surface flatness is improved, but device complexity increases
Solution Approach 1:
The patent performs the surface flatness formation in advance during the molding process itself, rather than performing complex machining operations after manufacturing the base structure, thereby simplifying the overall manufacturing process
Solution Approach 2:
The patent uses a molded resin body that inherently provides the required surface flatness through molding, eliminating the need for subsequent complex machining operations and reducing process complexity
