Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building partition screen mechanisms lack precise user control over the spring winding process, making it difficult to adjust the degree of spring winding and prevent uncontrolled rotation.
Innovation Solution
A spring winding assembly with a winding insert and sprung arms that allows for controlled winding and locking of the spring, featuring a central cross opening, bays with recesses and release openings, and a screw mechanism for secure locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple spring winding mechanism is used, then the device complexity is reduced, but the ease of operation deteriorates due to lack of precise user control
Solution Approach 1:
The winding insert is divided into multiple independent sprung arms (typically three) that can engage with corresponding bays in the socket. Each sprung arm operates independently to control the winding process, allowing precise incremental control while maintaining a relatively simple overall structure. The segmentation of the locking function across multiple arms provides both simplicity and operational precision.
Solution Approach 2:
The fin adapter acts as an intermediary element between the longitudinal spring seating means and the winding insert. It includes a roller cork that interfaces with the spring end, mediating the force transmission and providing a controlled interface for winding operations. This intermediary component simplifies the overall mechanism while enabling precise control.
2Ease of operation
If the spring winding mechanism is made accessible for user control, then the ease of operation is improved, but the reliability deteriorates due to risk of uncontrolled rotation
Solution Approach 1:
The sprung arms are pre-configured to engage with the bays in the socket, creating a preliminary locking action that prevents uncontrolled rotation before the user even begins winding. The arms are positioned to automatically engage with the bay recesses, providing inherent resistance to unintended rotation while still allowing controlled winding when the user applies force through the fin adapter.
Solution Approach 2:
The sprung arms provide tactile feedback to the user during the winding process. As the user winds the spring through the fin adapter, the engagement and disengagement of the sprung arms with the bays creates audible and tactile signals that indicate the winding state. This feedback mechanism ensures reliable control while maintaining ease of operation, as users can feel and hear the progression of winding without risking uncontrolled rotation.
3Reliability
If multiple sprung arms are used for locking, then the reliability of preventing spring unwinding is improved, but the device complexity increases
Solution Approach 1:
Each sprung arm serves multiple functions: it acts as a locking element, a control element, and a feedback element. The same sprung arm structure is repeated three times around the winding insert, with each arm engaging a corresponding bay. This universal design provides redundant locking security without requiring fundamentally different components, thereby increasing reliability while limiting complexity through standardization.
Solution Approach 2:
The winding insert integrates multiple functions into a single component: the sprung arms are directly attached to the insert body, combining the winding control mechanism and the locking mechanism into one unified element. Similarly, the socket integrates the bays and the release opening into a single structure. This merging reduces the total number of separate components while maintaining the multi-arm locking security.

Function Achieved in This Case
Facilitates precise adjustment of the spring winding and prevents uncontrolled rotation, ensuring stable guidance of the screening material and easy unlocking when needed.
Implementation Method 1
The spring becomes locked when the winding insert assumes a locked position, locking the spring so that it does not return to the unwound position from a wound position
Implementation Method 2
The cam comprising a toothed disc attached to the roller, and the coupler comprising a ridge
