Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling/uncoupling devices often experience unexpected loads when releasing coupled objects, which can be undesirable, and there is a need for a device that can quickly uncouple objects without considering the load on the objects.
Innovation Solution
A coupling/uncoupling device featuring a columnar member formed by semicircular members and coupling members with a circular holding section that allows for rotational movement, reducing the impact of external forces during uncoupling by using guide pins and restricting movement to the extending direction of the guide pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional coupling structure is used to couple and separably hold objects, then the coupling can be released, but unexpected loads are generated between the coupled objects or inside the objects during release
Solution Approach 1:
The columnar member is configured to be rotatable in both clockwise and counterclockwise directions along the circular inner surface section about a reference position. This dynamic rotational capability allows the coupling members to rotate during uncoupling, converting linear separation motion into rotational motion and reducing the impact load on the coupled objects.
Solution Approach 2:
The coupling members form a circular holding section with a circular inner surface section that contacts the outer circumferential surface of the columnar member. The circular geometry enables smooth rotational movement during uncoupling, allowing the columnar member to rotate about the reference position and reducing shock loads compared to linear separation.
2Object-affected harmful factors
If a coupling structure is designed to reduce load on objects during uncoupling, then the uncoupling process becomes controlled, but the uncoupling speed decreases
Solution Approach 1:
The columnar member can rotate in both clockwise and counterclockwise directions along the circular inner surface section, enabling dynamic adjustment of the uncoupling path. This bidirectional rotational capability allows for controlled, smooth separation that reduces load on objects while maintaining efficient uncoupling speed.
3Object-affected harmful factors
If the columnar member is configured to be rotatable along the circular inner surface section, then the impact of uncoupling is reduced, but the device complexity increases
Solution Approach 1:
The circular holding section with its circular inner surface section provides a simple yet effective curved path for the columnar member to follow during uncoupling. This circular geometry naturally guides the rotational movement, reducing the need for complex mechanical constraints while still achieving controlled, low-impact separation.

AI summary
A coupling/uncoupling device includes a columnar member configured by a divided pair of semicircular members, and a pair of coupling members forming a circular holding section that holds the columnar member. The circular holding section includes a circular inner surface section with which an outer circumferential surface of the columnar member is in slide contact, the circular inner surface section being formed from inner circumferential surfaces of a semicircular section in one coupling member and a semicircular section in the other coupling member. The columnar member is configured to be rotatable in both clockwise and counterclockwise directions along the circular inner surface section about a reference position where a contact surface of the pair of coupling members and a dividing surface of the columnar member are flush with each other.
