Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a two-piece structure is adopted for the automobile window, then the manufacturing complexity is reduced and ease of manufacture is improved, but the rigidity and strength are insufficient making the window prone to breakage
Solution Approach 1:
The automobile window is divided into multiple functional layers including outer glass sheet, inner glass sheet, intermediate adhesive layer, and stiffener layer, with each layer serving specific purposes. This segmentation allows optimization of each component for its specific function while maintaining overall structural integrity and manufacturability.
Solution Approach 2:
The patent employs a composite structure combining glass sheets with an adhesive layer and a stiffener layer made of rigid material. This composite construction integrates the transparency and smooth surface of glass with the rigidity and strength of the stiffener, resolving the contradiction between ease of manufacture and structural strength.
2Device complexity
If a two-piece structure is adopted for the automobile window, then the device complexity is reduced, but the reliability is compromised due to insufficient rigidity and increased breakage risk
Solution Approach 1:
The window structure is segmented into distinct functional layers (outer glass, inner glass, adhesive layer, stiffener) that can be manufactured and quality-tested separately, then assembled through lamination. This maintains manageable complexity while improving reliability through specialized design of each component.
Solution Approach 2:
The composite structure combining glass and stiffener layers creates a multi-functional system where each material contributes its superior properties. The glass provides transparency and the stiffener provides rigidity, together achieving high reliability without excessive overall complexity.
3Strength
If the stiffener is added to connect the glass sheets and housing, then the rigidity and durability are improved, but the device complexity increases
Solution Approach 1:
The stiffener layer is merged with the adhesive layer into a single integrated component during manufacturing. This combining approach provides the rigidity enhancement function of the stiffener while simplifying the manufacturing process by reducing the number of separate assembly steps, thus limiting the increase in device complexity.
Solution Approach 2:
The integration of the stiffener with the adhesive layer creates a composite component that performs multiple functions (bonding and structuring) simultaneously. This reduces the number of separate parts and assembly operations, limiting complexity increase while achieving the desired rigidity improvement.
