Problem
Existing assembly locking devices are complex and costly to manufacture and assemble, and they do not provide a simple and effective way to pre-install a connecting bolt in a component opening for subsequent connections.
Innovation Solution
A wire coil assembly locking device with a holding turn, clamping coil portion, and positioning turn is used to securely position and align a connecting bolt within a component opening, utilizing frictional forces for retention and allowing for elastic flexibility during the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multi-part assembly locking devices are used, then the connecting bolt can be secured in the component opening, but the manufacturing complexity and assembly complexity increase significantly
Solution Approach 1:
The patent merges multiple functional parts (retaining elements, positioning elements, and locking elements) into a single integrated assembly locking device. This single device comprises a body with retaining arms that have retaining elements for securing the connecting bolt, positioning elements for aligning the bolt, and locking elements for fixation, thereby reducing manufacturing and assembly complexity while maintaining securing reliability
Solution Approach 2:
The assembly locking device is designed as a multi-functional component that simultaneously performs retaining, positioning, and locking functions. The retaining arms can be adjusted to different positions to accommodate various connecting bolt configurations, making the device universally applicable for different assembly scenarios without requiring multiple specialized components
2Reliability
If traditional assembly locking devices with multiple parts are used, then the connecting bolt can be retained, but the time required for assembly increases
Solution Approach 1:
The assembly locking device is pre-configured with retaining arms at specific positions before the assembly process. The retaining elements are预先 positioned to engage with the connecting bolt, and the locking elements are prepared in advance. This preliminary preparation eliminates the need for complex step-by-step assembly operations during the actual assembly process, significantly reducing assembly time while ensuring reliable retention
Solution Approach 2:
The locking device incorporates segmented retaining arms that can be independently positioned and adjusted. These arms can be set at different angular positions around the body to accommodate various connecting bolt configurations. The segmentation allows for quick adjustment and installation without requiring complex alignment procedures, thereby reducing assembly time while maintaining secure retention
