Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing window processing technologies are used, then manufacturing simplicity is maintained, but the ability to create large bending angles is insufficient
Solution Approach 1:
The molding apparatus is divided into multiple independent components: a first molding part for the outer surface, a second molding part for the inner surface, and a jig with a groove. This segmentation allows each component to be optimized independently for creating large bending angles while maintaining ease of manufacture through modular assembly.
Solution Approach 2:
The groove in the jig acts as an intermediary structure that receives and guides the bendable portion of the window member. This intermediary element enables precise control of the bending process and final shape without requiring complex direct manipulation of the window material itself.
2Shape
If a molding apparatus with groove and multiple molding parts is used, then large bending angles are achieved, but device complexity increases
Solution Approach 1:
The first and second molding parts are configured to move relative to each other along the groove. This dynamic arrangement allows the apparatus to adapt to different bending requirements and window sizes while maintaining a relatively simple overall structure. The molding parts can be positioned at different locations along the groove depending on the specific shaping needs.
Solution Approach 2:
The groove structure serves multiple functions: it guides the bendable portion, provides support during molding, and accommodates the movement of molding parts. This multi-functionality reduces the need for additional specialized components, thereby managing device complexity while achieving complex bent shapes.
3Productivity
If conventional molding methods are used, then process simplicity is maintained, but productivity for curved windows is reduced
Solution Approach 1:
The groove is pre-configured with the exact shape and dimensions needed for the desired bent window. The bendable portion is inserted into this pre-prepared groove before molding begins, which streamlines the manufacturing process and eliminates the need for complex real-time adjustments during production, thereby improving productivity.
Solution Approach 2:
The invention replaces complex mechanical manipulation methods with a more efficient system where the groove geometry itself guides and defines the final shape. This substitution of geometric guidance for mechanical force application simplifies the control system and increases manufacturing efficiency for curved windows.
