Connecting Fitting with Parallelizing Means for Small Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting construction materials, such as a door frame and a wall, struggle to effectively connect materials with small intervals and ensure one material remains immobile relative to the other.
Innovation Solution
A connecting fitting system that uses first and second connecting members, along with parallelizing means, to align and connect the materials. The parallelizing function allows the members to be inserted with small intervals and then eliminates to create opposite inclination angles, securing the materials in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If connecting members are inserted between two construction materials with small intervals, then the connection can be achieved in limited space, but the connecting members cannot be properly aligned and secured
Solution Approach 1:
The parallelizing means performs preliminary alignment of the first and second connecting members before they are fully inserted and secured between the construction materials. This preliminary action ensures proper parallel alignment is achieved even in the limited space of small intervals, resolving the contradiction between compact installation space and alignment precision requirements
Solution Approach 2:
The parallelizing means acts as an intermediary device between the connecting members and the construction materials. It temporarily maintains the connecting members in a parallel state during insertion, then eliminates itself or its function after securing, allowing precise alignment to be achieved without requiring large installation space
2Strength
If connecting members are inserted to connect construction materials, then the materials can be joined, but one material cannot be rendered immobile relative to the other
Solution Approach 1:
The first and second connecting members are configured with asymmetric inclination angles relative to the direction of the interval between construction materials. This asymmetric configuration creates opposing forces that effectively prevent relative movement between the construction materials, rendering one material immobile with respect to the other while maintaining strong connection
Solution Approach 2:
The connecting members are designed with curved or inclined surfaces rather than straight perpendicular configurations. This curvature allows the connecting members to engage both construction materials at opposing angles, creating a mechanical interlock that prevents relative movement and ensures immobility while maintaining connection strength

AI summary
A connecting fitting for connecting two construction materials includes a first and second connecting members for connecting the construction materials, and a parallelizing means having a parallelizing function of aligning the connecting members in a first direction and making them parallel or almost parallel to each other. The first direction is a direction perpendicular to both the direction (M) of an interval between the two construction materials and the thickness direction of one construction material. The parallelizing function of the parallelizing means disappears due to a load caused to act on at least one of the connecting members. The inclination angles of the connecting members with respect to the direction (M) of the interval become inclination angles (θ1, θ2) opposite to each other due to the disappearance of the parallelizing function.
