Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener structures for combining and separating plate bodies are not easily reversible, making it difficult to quickly and repeatedly assemble and disassemble two plate bodies.
Innovation Solution
A fastener structure comprising a body portion with a solderable layer and a movably attaching fastening body, which can be easily combined and separated by using a tool to rotate the fastening body's head, allowing for quick and repeated assembly and disassembly by soldering and unsoldering the body portion to a plate body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fasten two plate bodies, then the connection strength is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The fastener is divided into two main segments: a body portion that is permanently soldered to one plate body, and a fastening body that can be repeatedly attached and detached. This segmentation allows the permanent connection (body portion) to provide stable mounting while the removable segment (fastening body) enables easy assembly and disassembly operations.
Solution Approach 2:
The body portion is preliminarily soldered to the plate body during manufacturing, creating a permanent base connection before use. This preliminary action ensures strong, reliable mounting while allowing the fastening body to be freely attached and detached as needed, resolving the contradiction between connection strength and ease of operation.
2Reliability
If screws are used to combine plate bodies, then the reliability of connection is improved, but the productivity for repeated assembly deteriorates
Solution Approach 1:
The fastener system is segmented into a permanently mounted body portion (providing reliable connection through soldering) and a reusable fastening body (enabling quick attachment/detachment). This allows high-reliability connections to be maintained while dramatically improving productivity for repeated assembly operations.
Solution Approach 2:
The traditional mechanical screw fastening system is replaced with a hybrid system combining permanent soldering (for reliability) and a simplified mechanical attachment mechanism (for productivity). The elastic element provides automatic engagement force, eliminating the need for threading operations and improving assembly speed while maintaining connection reliability.
3Ease of manufacture
If a solderable layer is added to the body portion, then the ease of manufacture is improved, but the device complexity increases
Solution Approach 1:
The solderable layer is merged with the body portion as an integrated component, combining the mounting base and connection interface into a single manufacturable unit. This integration simplifies the manufacturing process by reducing the number of separate components while adding only minimal complexity to the device structure.
Solution Approach 2:
The addition of a solderable layer changes the material parameter of the body portion, enabling permanent attachment to plate bodies. This parameter change (adding solderability) is a simple manufacturing modification that does not significantly increase device complexity, as the layer is applied during standard manufacturing processes.

AI summary
A fastener structure includes a body portion and a fastening body. The body portion has a solderable layer, and the solderable layer is soldered to a plate body. The fastening body combines movably with the body portion. The fastening body has a head and a fastening portion. The body portion or the fastening body, or both the body portion and the fastening body is provided on the plate body for soldering after it is picked up by a tool so that the body portion can combine with the plate body. Also, the body portion or the fastening body, or both the body portion and the fastening body combines with a assisting pickup unit, and the fastener structure is provided on the plate body for soldering after it is picked up by a tool through the assisting pickup unit so that the body portion can combine with the plate body.
