Solution Overview
Problem
Conventional assembled structures require a large number of screws and joining metal fittings, leading to complexity and potential loss of components, and often compromise on strength and appearance due to varying joint member shapes and orientations.
Innovation Solution
An assembled structure featuring a joint member with specific openings and a fixing member that uses convex and concave portions to securely engage frame members with a reduced number of components, allowing for easy assembly and maintaining strength across different orientations without protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional assembled structures use a large number of screws and joining metal fittings, then connection strength is improved, but device complexity increases and components may be lost
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated joint member. The joint member incorporates multiple openings for different frame members and integrates both convex portions for engagement and concave portions for screw fixation, eliminating the need for separate joining metal fittings and reducing the total number of components while maintaining connection strength.
Solution Approach 2:
The joint member is designed as a universal component that can connect multiple types of frame members (first, second, and third frame members) through its multiple openings. It performs multiple functions: structural support, positioning through convex portions, and secure fixation through concave portions with screws, replacing the need for multiple specialized fasteners.
2Adaptability or versatility
If conventional assembled structures use varying joint member shapes and orientations, then adaptability is improved, but appearance is compromised due to protrusions
Solution Approach 1:
The joint member features asymmetric design with convex portions positioned on specific sides and corresponding concave portions on opposite sides. This asymmetric configuration allows the joint member to adapt to different frame member orientations and positions while maintaining a clean appearance, as the convex portions fit precisely into corresponding recesses without creating external protrusions.
Solution Approach 2:
The convex portions are designed to nest within corresponding concave portions of the joint member or frame members. This nesting arrangement allows the connecting components to be hidden within the structure rather than protruding outward, maintaining a clean appearance while providing adaptable connection capabilities for various orientations.

AI summary
An assembled structure includes a joint member including a first opening arranged on a first surface, a second opening arranged on a second surface adjacent to the first surface, and a third opening arranged on a third surface adjacent to the first surface and arranged at a position corresponding to the second surface, a first frame member inserted into the first opening and having a first convex portion at an end portion in a longitudinal direction, a second frame member inserted into the second opening and having a second convex portion at an end portion, and a fixing member inserted into the third opening and fixing the first frame member and the second frame member.
