Solution Overview
Problem
Conventional fastening technologies for metal studs lack ready detachability and reusability, making them unsuitable for applications requiring temporary or modular configurations.
Innovation Solution
A removable fastener system featuring a joining member with notches that secure the edges of apertures together and a locking member to maintain the attachment, allowing for rapid assembly and disassembly of metal studs in a back-to-back configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fastening technology (bolts or rivets) is used to secure metal studs, then the connection strength and structural stability are improved, but the detachability and reusability deteriorate
Solution Approach 1:
The fastening system is divided into separate components: a joining member with notches that fits into apertures, and a locking member that secures it. This segmentation allows the connection to be strong when assembled while remaining detachable by removing the locking member and joining member, thus resolving the contradiction between connection strength and detachability.
Solution Approach 2:
The fastening system transitions from a static permanent connection (bolts/rivets) to a dynamic reversible connection. The locking member can be engaged to provide strong connection and disengaged to allow detachment, enabling the system to adapt between strong fixed state and easily detachable state based on operational needs.
2Stability of the object's composition
If conventional fastening technology is used to secure metal studs, then the structural stability is improved, but the reusability deteriorates
Solution Approach 1:
By segmenting the fastening system into a joining member and locking member that can be repeatedly assembled and disassembled, the system maintains structural stability during use while enabling reusability across multiple applications. The standardized aperture and joining member design allow consistent reassembly, ensuring both stability and reusability.
Solution Approach 2:
The fastening system is designed to be recovered and reused rather than discarded. The joining member and locking member can be removed and reused in different configurations or locations, maintaining structural stability in each new application while providing high reusability, thus resolving the contradiction between stability and reusability.
3Adaptability or versatility
If a removable fastening system with joining member and locking member is used, then the detachability and reusability are improved, but the device complexity increases
Solution Approach 1:
While segmentation into joining member and locking member enables detachability, the design minimizes complexity by using simple geometric forms: notches cut into the joining member and a basic locking mechanism. This keeps the segmented structure relatively simple while achieving the desired detachability.
Solution Approach 2:
The joining member acts as an intermediary element that simplifies the overall fastening process. Rather than directly connecting structural elements, the joining member with its notches provides a standardized interface that the locking member secures, simplifying the detachable connection mechanism while maintaining adaptability.
4Productivity
If a removable fastening system is used to enable rapid assembly and disassembly, then the productivity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The joining member is designed with notches and the structural elements with apertures in predetermined positions before assembly. This preliminary preparation of precise features allows for rapid assembly without requiring high precision during the actual fastening operation, thus improving productivity while maintaining necessary manufacturing precision in the design phase.
Solution Approach 2:
The segmentation into standardized components with predefined geometric features (notches and apertures) allows for modular assembly. The standardized interfaces reduce the precision requirements during assembly compared to custom-fit connections, enabling rapid assembly while maintaining adequate manufacturing precision through standardization.

AI summary
A removable fastener for securing a first stud to a second stud each stud having an aperture with lateral and bottom edges, includes a joining member with a first end and second end having first and second notches sized to admit lateral edges made adjacent by placing the studs back-to-back. Fastener includes a locking member that has a stud end configured to rest on the bottom edges of the apertures and a fastener end configured to attach to the joining member, holding the joining member in position within the apertures when the joining member is engaged within the apertures; the fastener end may include a clip.
