Rotary Uncoupling Structure for Controlled Load Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling/uncoupling devices often experience unexpected loads when releasing a coupled state, which is undesirable, and there is a need for quicker uncoupling without considering the load on the objects, necessitating an improvement in the uncoupling process.
Innovation Solution
A coupling/uncoupling device with a columnar member that can be rotated to achieve a desired uncoupled state, utilizing guide pins and semicircular fixed members to restrict movement and apply a separating force, allowing for controlled uncoupling by rotating a fixed shaft to loosen the adhesion between coupling members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional coupling/uncoupling device is used to release a coupled state, then the coupling can be released, but unexpected loads are generated between the coupled objects or inside the objects
Solution Approach 1:
The patent applies preliminary action by introducing a columnar member that can be rotated to a preliminary position before actual uncoupling. This preliminary positioning allows the coupling members to be gradually separated in a controlled manner, preventing sudden load generation on the objects during the uncoupling process
Solution Approach 2:
The patent implements dynamics by making the columnar member rotatable to different positions (first position for preliminary uncoupling, second position for complete uncoupling). This dynamic adjustment allows the system to transition from a coupled state to an uncoupled state in a controlled, staged manner rather than abruptly, thereby avoiding unexpected loads
2Productivity
If a conventional coupling/uncoupling device is used for quick uncoupling, then separation speed is improved, but load on the objects is not controlled
Solution Approach 1:
The patent applies dynamics by providing a rotatable columnar member that can be quickly rotated between different positions. The first position enables quick preliminary uncoupling, and the second position enables complete uncoupling, allowing the system to achieve fast separation while maintaining control over the uncoupling process through rotational positioning
Solution Approach 2:
The patent segments the uncoupling process into two distinct stages controlled by the columnar member position: preliminary uncoupling at the first position and complete uncoupling at the second position. This segmentation allows for controlled, staged separation that maintains object safety while achieving quick uncoupling

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 is in contact with the columnar member along an outer circumferential surface of the columnar member and 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 by disposing the semicircular section in one coupling member and the semicircular section in the other coupling member to be opposed to each other so that the inner circumferential surfaces are continuous. 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.
