Torsion Spring Winding Tool with Resilient Bar Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing torsion spring winding tools lack ease of use, safety, and efficiency in manipulating and orienting bars relative to each other, and do not prevent accidental dropping or overextension of springs, leading to user inconvenience and potential safety hazards.
Innovation Solution
A torsion spring winding tool with two bars connected by a resilient connector and covered with a protective sleeve, allowing for unrestricted movement and orientation of the bars, with collars serving as handles, seats, and lugs, and a spring force mechanism to secure the bars in place, preventing accidental dropping and overextension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional rigid connection methods are used to join bars, then structural stability is improved, but ease of manipulation and orientation is worsened
Solution Approach 1:
The connector changes its physical state from rigid to flexible, allowing the bars to be easily manipulated and oriented during operation while maintaining structural stability when needed. The flexible nature enables dynamic adjustment of bar positions without compromising the overall structure.
Solution Approach 2:
The connection between bars transitions from static to dynamic, allowing movement and repositioning during operation. The flexible connector enables the bars to move relative to each other while maintaining connection, providing both ease of manipulation and structural integrity.
2Ease of operation
If bars are freely movable relative to each other, then ease of orientation is improved, but accidental dropping is worsened
Solution Approach 1:
The flexible connector acts as an intermediary element between the bars, allowing free movement and orientation while simultaneously preventing accidental dropping. It mediates between the need for mobility and the need for security, enabling bars to be repositioned easily but retained when engaged.
3Ease of operation
If no protective covering is used on the spring, then accessibility is improved, but spring damage is worsened
Solution Approach 1:
A flexible protective covering is applied to the spring, providing protection against damage while maintaining accessibility. The flexible nature of the covering allows operators to access and manipulate the spring components without removing protection, reducing the risk of damage during operation.

AI summary
The present invention relates to a torsion spring winding tool, and in particular to a tool having two bars that are joined with a connector. Each bar can have a shaft with two ends. Two collars are connected to each shaft, generally near the second end of the shafts. The collars separate the bars into three sections, namely a handle, a seat and a lug. A connector is provided and connects the bars together in the seats. The connector can be a spring that is covered with a cover. A user can use the handles to manipulate the bars. The lugs can be inserted into pockets of a spring cone to wind and unwind a torsion spring.
