Solution Overview
Problem
The challenge lies in simplifying the assembly process of connecting two components using threaded bolts, particularly in difficult-to-access positions, where aligning through holes and inserting threaded bolts is time-consuming and prone to errors.
Innovation Solution
A mounting lock with a cylindrical helix featuring retaining, transition, and blocking turns is adapted to threaded bolts, ensuring secure positioning within through holes by creating a friction-locking connection and preventing pullout, utilizing standardized thread geometries to determine wire diameter and inner diameter for reliable fitment.

1Productivity
If traditional threaded bolts are used to connect two components through through holes, then the connection can be established, but the alignment of through holes and insertion of threaded bolts is time-consuming and error-prone
Solution Approach 1:
The mounting lock is pre-assembled on the threaded bolt before insertion, with the blocking turn positioned to engage with the through hole edge. This preliminary configuration eliminates the need for complex alignment operations during assembly, as the mounting lock guides the threaded bolt into the correct position automatically.
Solution Approach 2:
The mounting lock acts as an intermediary component between the threaded bolt and the through hole. It simplifies the connection process by providing a guided insertion path and automatic positioning mechanism, mediating the interaction between the bolt and the hole to achieve rapid assembly without precise manual alignment.
2Ease of operation
If the blocking turn is designed with elastic displacement capability, then the threaded bolt can be easily inserted into the through hole, but the structure becomes more complex
Solution Approach 1:
The blocking turn is designed with elastic properties that allow it to dynamically change its radial position. During insertion, the blocking turn can elastically displace radially inward to pass through the through hole edge, then returns to its original position to provide blocking function. This dynamic behavior enables easy insertion while maintaining a relatively simple structure.
Solution Approach 2:
The blocking turn utilizes changes in its physical state (elastic deformation) to achieve different functional requirements. By changing its radial dimension through elastic displacement, the blocking turn can transition between a blocking state (preventing pullout) and a pass-through state (allowing insertion), thereby simplifying the insertion process without requiring complex mechanical mechanisms.
