Coil Locking Mechanism With Freewheel Tensioning and Secure Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices fail to provide a reliable method for both detachable connection and clamping of assemblies, lacking a mechanism to efficiently tension components relative to each other.
Innovation Solution
A closure device comprising two interlocking parts with a winding element and actuating mechanism, allowing for the winding and unwinding of a tension element, which can be rotated to secure or release the assembly, utilizing engagement devices and toothing systems for secure hold and freewheel functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a closure device uses simple attachment mechanisms, then ease of operation is improved, but reliability of connection and tensioning capability deteriorates
Solution Approach 1:
The patent combines a closure mechanism with a tensioning mechanism into a single integrated device. The closure parts not only attach to each other but also incorporate a winding element that can tension a tension element between assemblies, resolving the contradiction by merging two functions (closure and tensioning) that were previously separate devices
Solution Approach 2:
The closure device serves multiple functions: it provides detachable connection between assemblies, enables tensioning of components relative to each other, and allows for easy adjustment and release. This multi-functionality addresses the contradiction by making a single device that both securely connects and actively tensions assemblies
2Adaptability or versatility
If a closure device incorporates both closure and tensioning functions, then versatility is improved, but device complexity increases
Solution Approach 1:
The winding element is rotatably mounted on the first closure part, nesting the tensioning mechanism within the closure structure. The tension element passes through or around the winding element, creating a compact nested arrangement that provides versatile functionality without proportionally increasing device complexity
Solution Approach 2:
The device is divided into distinct functional components: closure parts for connection, a winding element for tensioning, and a tension element for applying force. This segmentation allows each component to perform its specific function efficiently while maintaining overall versatility without excessive complexity
3Ease of operation
If the winding element is freely rotatable, then ease of adjustment is improved, but secure hold capability deteriorates
Solution Approach 1:
The engagement devices transition between engaged and disengaged states dynamically. When engaged, they provide a secure hold preventing rotation; when disengaged, they allow free rotation for adjustment. This dynamic state change resolves the contradiction by providing both secure holding and easy adjustment at different operational phases
4Reliability
If engagement devices are always engaged, then secure hold is improved, but ease of release deteriorates
Solution Approach 1:
The closure parts are designed to automatically engage with each other when brought together, and the engagement devices automatically disengage when the closure parts are separated. This self-service mechanism eliminates the need for manual engagement or disengagement operations, resolving the contradiction by providing secure hold during use while enabling easy release through simple separation of closure parts

AI summary
A locking device (1) comprises a first locking part (2) and a second locking part (3), which can be attached to one another along a closing direction (X), are held against each other in a closed position, and can be separated from each other to open the locking device (1). The second locking part (3) has an actuating element (34) with a first engagement device (345) and a winding element (35) arranged on the actuating element (34), which is rotatable in a winding direction (V) for winding a pull element (4) and has a second engagement device (355). The first engagement device (345) and the second engagement device (355) are not engaged with each other in a release position, so that the winding element (35) is rotatable relative to the actuating element (34), and can be brought into engagement with each other so that, in an engagement position, the winding element (35) is rotatable via the actuating element (34).wherein the first locking part (2) has a first toothing device (25) and the second locking part (3) has a second toothing device (351) and the first toothing device (25) and the second toothing device (351) engage with each other in the closed position of the locking device (1) such that the first locking part (2) and the second locking part (3) are held positively to each other along the winding direction (V).
