Locking Device Mounting via Edge Contact and Pin Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing locking devices for opening and closing members, such as vehicle glove compartments, are complicated to mount due to the need to align and insert positioning pins into holes, making the process time-consuming.
Innovation Solution
A locking device with a base member and a driving member, featuring a first locating portion that contacts the edge of an opening portion and a second locating portion that is inserted into a locating hole, allowing for easy alignment and mounting by restricting relative displacement between the two portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a positioning pin is inserted into a positioning hole for mounting the locking device, then positioning accuracy is improved, but the mounting complexity and time increase
Solution Approach 1:
The positioning function is divided into two independent portions: the first locating portion contacts the edge portion of the opening portion, while the second locating portion inserts into the locating hole. This segmentation allows each portion to perform its specific positioning function independently, simplifying the overall mounting process while maintaining positioning accuracy
Solution Approach 2:
The first locating portion is designed to contact the edge portion of the opening portion before the second locating portion is inserted into the locating hole. This preliminary action guides the locking device into approximate position, making the subsequent insertion of the second locating portion easier and faster
2Measurement precision
If a positioning pin is inserted into a positioning hole for mounting the locking device, then positioning accuracy is improved, but the mounting time increases
Solution Approach 1:
The positioning function is divided into two independent portions that can be engaged in sequence. The first locating portion contacts the edge portion first, establishing preliminary positioning, while the second locating portion is then inserted into the locating hole to complete the positioning. This segmentation enables faster mounting compared to requiring precise alignment of a single positioning pin
Solution Approach 2:
The first locating portion performs preliminary positioning by contacting the edge portion of the opening portion before the second locating portion is inserted. This preliminary action reduces the time required for precise alignment, as the locking device is already approximately positioned when the second locating portion is engaged

AI summary
A rotor member in a locking device is rotatably supported in a base member, is connected to a locking member by projecting to the back side from an opening portion formed in a mounting seat face, and drives the locking member in accordance with the operation of an operating member. A first locating portion of the base member abuts or is near an edge portion of the opening. A second locating portion is inserted into a locating hole formed in an opening and closing member. The first locating portion projects further toward the back side than the second locating member.
