Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for structural members, such as metal studs, do not allow for secure end-on joining and require specialized tools or skills, and are not easily disassembled.
Innovation Solution
A fastening system comprising a latching device with eccentric rotatable parts and latch spring hooks, which engages a receiver to securely fasten one structural member end-on to another, using a simple tool for assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional fasteners (nails, screws, rivets) are used to join structural members, then the joining is secure, but the process is time-consuming and requires specialized tools or skills
Solution Approach 1:
The fastening system is divided into two separate components: a latch component attached to one structural member and a receiver component attached to the other. This segmentation allows each component to be optimized independently and enables quick engagement without specialized tools, as the latch simply needs to be inserted into and rotated within the receiver.
Solution Approach 2:
The latch component incorporates a rotatable part that transitions between engaged and disengaged positions. This dynamic mechanism allows the fastener to be quickly secured by rotation and equally quickly released by reverse rotation, eliminating the need for specialized installation and removal tools while maintaining secure joining.
2Adaptability or versatility
If latch and receiver fasteners are used to join metal studs in parallel arrangements, then the fastening is secure, but the system does not allow end-on joining of structural members
Solution Approach 1:
The latch and receiver fastening system is designed to be universal, accommodating multiple joining configurations including parallel arrangements and end-on connections. The receiver component's open structure and the latch's rotational engagement mechanism work effectively regardless of the relative orientation of the structural members, providing both versatility and reliable fastening.
3Ease of operation
If permanent fastening methods are used, then the joining is secure, but the structure cannot be easily disassembled
Solution Approach 1:
The rotational latch mechanism provides a dynamic fastening solution that is both secure and reversible. The latch engages securely with the receiver through rotation, providing reliable joining, but can be just as easily disassembled by rotating the latch in the opposite direction, enabling quick release without damaging the structural members.

AI summary
A fastening system for joining two structural members is provided. The fastening system includes a latching device comprising a housing, at least one eccentric rotatable part and a generally S shaped latch spring hook joined to the rotatable part, and a receiver having at least one hole configured to receive a free end of the latch spring hook. In one embodiment, the bottom portion of the housing is generally semi-circular in shape and the receiver includes two semi-circular frames having a corresponding radius to receive the lower portion of the housing. The latching device is fixed to a first structural member and the receiver is fixed to a second structural member. The structural members may be joined by positioning an end of the first structural member adjacent to the receiver of the second structural member and rotating the rotatable part to cause the free end of the latch spring hook to engage the hole in the receiver. Further rotation of the eccentric rotatable part causes the latch spring hook to exert a pulling force, thereby joining the structural members together. The semi-circular lower portion of the housing and the semi-circular frames on the receiver allows the structural members to be attached at any desired angle using one fastening system.
