Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors that use screw-coupling for connecting target objects often experience unlocking issues over time due to weakened coupling force, requiring additional assembly steps and external lock wires that are inconvenient and prone to damage.
Innovation Solution
A connector design featuring a housing with a thread groove and protruding portions or fixing grooves that prevent rotation by coupling with each other, eliminating the need for external wires and enhancing assembly efficiency and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock wire is used to prevent unlocking between the target object and connector, then the coupling reliability is improved, but the assembly time increases excessively and the device complexity increases
Solution Approach 1:
The patent combines the locking function and coupling function into a single integrated structure. The locking members are formed as integral parts of the connector housing and target object housing, eliminating the need for separate lock wires. This merging of functions allows the locking mechanism to be applied automatically during the coupling process, thereby maintaining high reliability while significantly reducing assembly time.
Solution Approach 2:
The connector employs self-locking members that automatically engage when the connector and target object are coupled together. The locking members on the connector housing and target object housing interact to provide automatic locking without requiring external lock wires or additional assembly steps. This self-service mechanism ensures reliable coupling while minimizing assembly time.
2Reliability
If a lock wire is used to prevent unlocking, then the coupling reliability is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the locking mechanism directly into the connector and target object structures. The locking members are formed as integral parts of the respective housings, combining the coupling and locking functions into a unified design. This eliminates the need for separate external lock wires and reduces overall device complexity while maintaining reliable coupling.
Solution Approach 2:
The self-locking members automatically engage when the connector and target object are coupled, providing inherent locking functionality without requiring additional components. This self-service approach reduces device complexity by eliminating external locking mechanisms while ensuring reliable prevention of unlocking.
3Reliability
If a lock wire is used to prevent unlocking, then the coupling reliability is improved, but the ease of operation deteriorates due to inconvenient assembly
Solution Approach 1:
The patent merges the locking function with the coupling operation itself. The locking members are positioned such that they automatically engage when the connector and target object are brought together, eliminating the need for separate locking steps. This integration maintains high reliability while significantly improving ease of assembly.
Solution Approach 2:
The self-locking members provide automatic locking during the coupling process, requiring no additional manual intervention. This self-service mechanism ensures reliable coupling prevention while making the assembly process simple and convenient, thereby improving ease of operation.

AI summary
Disclosed is a connector for preventing unlocking. The connector for preventing unlocking may includes a signal pin transferring a signal; a body into which the signal pin is inserted and which is electrically isolated from the signal pin by an insulator and transfers a ground voltage; a first housing having a hollow portion defined therein, into which one end of the body is inserted, a thread groove for screw-coupling, which is defined in an inner circumferential surface of one end thereof, and at least one protruding portion or a plurality of fixing grooves formed on or in an inner circumferential surface of the other end thereof; and a second housing having a hollow portion defined therein, into which the other end of the body is inserted and through which the second housing is moved along an outer circumferential surface of the body in an axial direction, and one of the at least one protruding portion and the plurality of fixing grooves, which is not formed at the first housing but is formed on or in an outer circumferential surface of one end thereof. When the one end of the second housing is inserted and fixed between the inner circumferential surface of the other end of the first housing and the outer circumferential surface of the body, the at least one protruding portion is coupled in the plurality of fixing grooves so as to prevent rotation of the first housing.
