Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a complex structure is used to position one building material in the thickness direction and couple two materials, then positioning accuracy and coupling reliability are improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The coupler is divided into two functional parts: a foundation member with guide portions that provides positioning guidance, and a coupling member that provides structural coupling. This segmentation allows each part to be optimized independently, simplifying the overall structure while maintaining positioning accuracy through the guide portions.
Solution Approach 2:
The guide portions on the foundation member act as an intermediary mechanism between the two building materials. These guide portions temporarily guide and position the coupling member during installation, enabling accurate positioning without requiring a complex fixed structure. After positioning, the coupling member's rigid structure maintains the positional relationship.
2Reliability
If a complex structure is used to position one building material in the thickness direction and couple two materials, then coupling reliability is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the coupler into foundation member and coupling member with distinct functions, each component can be manufactured using simpler, more cost-effective processes. The guide portions are integrated into the foundation member rather than being separate components, reducing part count and assembly complexity while maintaining coupling reliability.
Solution Approach 2:
The guide portions are merged with the foundation member as an integrated structure rather than being separate guide components. This merging reduces the total number of parts, simplifies manufacturing, and lowers assembly requirements while still providing the necessary positioning and coupling functions for reliable installation.
3Manufacturing precision
If guide portions with different tilting directions or angles are provided, then positioning accuracy in the thickness direction is improved, but coupler structure complexity increases
Solution Approach 1:
Different guide portions on the foundation member have different local qualities in terms of their tilting directions or angles. Each guide portion is specifically configured with the appropriate tilt for its particular positioning requirement, allowing accurate positioning in the thickness direction while maintaining a relatively simple overall structure through this localized differentiation approach.

AI summary
Two building materials are coupled by a plurality of couplers (10A). Each coupler includes a foundation member (20) arranged on one building material (2), and a coupling member (21) extending from the foundation member to the side of the other building material and joined to the other building material by a joint. The foundation member is provided with a guide portion formed by an outer edge portion (20A, 20B) configured to guide the coupling member movably in a direction having a component in a thickness direction of the one building material. At least two couplers are provided on the one building material in a direction orthogonal to a direction of the interval and the thickness direction of the one building material. The guide portions of the foundation members of the couplers have different tilting directions or tilting angles with respect to the direction orthogonal to the direction of the interval and the thickness direction of the one building material. It is therefore possible to implement, by couplers having a simple structure, positioning one building material in the thickness direction of the one building material and coupling two building materials by a plurality of couplers.
