Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fasteners are used, then assembly is simple, but they loosen under severe vibration causing safety issues
Solution Approach 1:
The fastening system is divided into distinct functional components: a connecting piece with external threads, a nut with internal threads, and a separate anti-rotating seat. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity. The anti-rotating seat specifically prevents rotation, while the nut provides the fastening force, resolving the contradiction between reliability and complexity.
Solution Approach 2:
The anti-rotating seat acts as an intermediary component between the connecting piece and the workpiece. It prevents the connecting piece from rotating during vibration while allowing the nut to maintain the fastening force. This intermediary element solves the loosening problem without requiring complex integrated designs, thus maintaining structural simplicity while improving reliability.
2Reliability
If complex anti-loosening structures are used, then anti-vibration performance improves, but production cost increases
Solution Approach 1:
By segmenting the anti-loosening function into a separate anti-rotating seat component, each part can be manufactured using standard, cost-effective processes. The simple geometric features (external threads, internal threads, and basic anti-rotating geometry) are easy to manufacture with conventional machining, avoiding the need for expensive complex integrated components or specialized manufacturing processes.
Solution Approach 2:
The connecting piece and nut are designed to be self-aligning and self-assembling through their threaded connections. The anti-rotating seat automatically engages with the connecting piece to prevent rotation without requiring additional adjustment or complex assembly steps. This self-service design reduces manufacturing and assembly costs while maintaining effective anti-vibration performance.
3Adaptability or versatility
If conventional fasteners are used, then assembly is simple, but they cannot be repeatedly disassembled and assembled
Solution Approach 1:
The segmented design with separate connecting piece, nut, and anti-rotating seat components allows each part to be independently inspected, cleaned, and reused. The standardized threaded interfaces ensure consistent reassembly, enabling multiple disassembly and assembly cycles without degradation of function, thus improving reusability without significantly increasing assembly complexity.
Solution Approach 2:
The design allows for easy recovery and reuse of all components after disassembly. The anti-rotating seat remains in place on the workpiece, while the connecting piece and nut can be completely removed, cleaned, and reinstalled. This recoverability feature enables repeated use of the fastening system, improving adaptability for maintenance and reconfiguration operations.
4Productivity
If conventional fasteners are used, then assembly is simple, but production efficiency decreases due to inability to quickly disassemble
Solution Approach 1:
The segmented design with clearly defined components and standardized threaded interfaces enables rapid disassembly by simply unscrewing the nut from the connecting piece. The anti-rotating seat remains stationary on the workpiece, allowing the connecting piece and nut to be quickly removed and replaced. This segmentation facilitates fast maintenance and reconfiguration, improving productivity despite the slightly increased complexity of having multiple components.

AI summary
The present disclosure belongs to the technical field of machining and discloses a conductive fastening mechanism. The conductive fastening mechanism includes: a nut 1 connected to an energy load module 11 and electrically connected to a power supply through a power switch S0; an anti-rotating seat 2 located above the nut 1; a conducting element 8 arranged in the anti-rotating seat 2 and electrically connected to a load 13; a connecting piece 3 penetrating the anti-rotating seat 2 and the conducting element 8 and selectively connected to the nut 1, used for on-off between the load and the power supply; and a handle 4 rotatably arranged on the connecting piece 3, where the handle 4 is configured to be selectively clamped in the anti-rotating seat 2 to limit the connecting piece 3. The conductive fastening mechanism is simple to assemble and low in production cost, can meet needs for quick disassembly and assembly, can be repeatedly operated, and improves operation efficiency. In addition, the handle 4 is rotatably arranged on the connecting piece 3 and can be selectively clamped on the anti-rotating seat 2, such that the handle 4 plays a role in preventing the connecting piece 3 from rotating, so as to achieve the purpose of anti-vibration and anti-loosening, prevent damage and other safety accidents, and improve safety.
