Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex coupling structure is used to couple two building materials at an interval, then the coupling strength and reliability are improved, but the device complexity and cost increase
Solution Approach 1:
The coupling member is divided into a base portion and a coupling portion that can be bent relative to each other. This segmentation allows the coupling member to adapt to different installation conditions while maintaining a simple overall structure, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The coupling portion is designed to be bendable relative to the base portion, introducing dynamic flexibility to an otherwise static coupling structure. This allows the coupler to accommodate variations in installation geometry without requiring complex adjustable mechanisms, thereby maintaining reliability while keeping the structure simple.
2Reliability
If a complex coupling structure is used to couple two building materials at an interval, then the coupling strength and reliability are improved, but the manufacturing cost increases
Solution Approach 1:
By dividing the coupling member into bendable portions, the structure can achieve reliable coupling through simple geometric configuration rather than complex mechanical components, significantly reducing manufacturing cost while maintaining coupling reliability.
Solution Approach 2:
The bendable coupling portion allows for parameter adjustment in the form of bending angle and shape, enabling the same simple structure to adapt to different installation conditions without requiring multiple specialized components, thereby reducing manufacturing cost while ensuring reliability.
3Ease of manufacture
If a simple coupling structure is used to reduce cost, then the manufacturing cost decreases, but the coupling reliability and strength may be compromised
Solution Approach 1:
The bendable coupling portion provides dynamic adaptation capability, allowing the simple structure to achieve reliable coupling by adjusting its shape during installation to match the actual geometric conditions, thereby compensating for the simplicity of the structure through flexibility.
Solution Approach 2:
The ability to bend the coupling portion changes the geometric parameters of the coupler during installation, enabling a simple structure to achieve optimal coupling configuration for reliable attachment to building materials at various intervals and angles.
4Adaptability or versatility
If the coupling portion is made bendable, then the adaptability to different installation conditions is improved, but the structural complexity increases
Solution Approach 1:
The coupling member is segmented into a base portion and a coupling portion with distinct functions. The base portion provides stable attachment to one building material, while the coupling portion provides bending flexibility for adaptation, achieving high installability through functional segmentation without overall structural complexity.

AI summary
A coupler (10A) couples a door frame (2) and an auxiliary member (8) on a wall side. The coupler (10A) includes a foundation member (20) arranged on the door frame (2), and a coupling member (21) having a length extending from the foundation member (20) to a side of the auxiliary member (8) and joined to the auxiliary member (8) by a joint (24, 25). The coupling member (21) includes a base portion (21A) arranged on the foundation member (20), and a coupling portion (21B, 21C) extending from the base portion (21A). The coupling portion (21B, 21C) can be bent with respect to the base portion (21A). The coupling portion (21B, 21C) bent to the side of the auxiliary member (8) with respect to the base portion (21A) is joined to the auxiliary member (8) by the joint (24, 25). This can simplify the structure of the building material coupler.
