Wire Reel Clip Locking From Inside a Covered Flange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire winding devices fail to automate the locking process when the clip is completely covered by the flange, as they cannot be opened from the outside, preventing the terminal end portion from being locked securely.
Innovation Solution
A wire winding device with a lock jig that can open the clip from inside the flange by using a pair of tip end portions to approach each other or separate, allowing the pulled-out wire to be inserted and locked into the clip, even when the clip is covered, utilizing a reel driving portion, wire feeding portion, and control portion to manage the winding and locking process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the clip is completely covered with the flange, then the reel structure is compact and secure, but the clip cannot be pushed in the axial direction from outside the flange to open it
Solution Approach 1:
Instead of opening the clip from outside the flange in the axial direction, the invention opens the clip from inside the flange in the radial direction. The lock jig approaches the clip from the inner circumferential side and pushes the tip end portion of the clip in the radial direction to open it, reversing the conventional opening direction and location.
Solution Approach 2:
The lock jig acts as an intermediary tool that enables clip opening from inside the flange. It includes a pair of tip end portions that sandwich the pulled-out part of the wire and push against the tip end portion of the clip to open it, serving as a mediator between the wire and the clip.
2Strength
If the clip is covered with the flange, then the reel has improved structural integrity, but automated locking cannot be performed using conventional devices
Solution Approach 1:
The invention inverts the conventional approach by opening the clip from inside the flange rather than from outside. This allows automated locking to be performed on reels with covered clips, maintaining structural integrity while enabling automation through the lock jig that operates from the inner circumferential side.
Solution Approach 2:
The wire feeding portion applies tension to the pulled-out part of the wire, and the lock jig uses this tensioned wire to open the clip by sandwiching and pushing it. The system uses the wire's own tension to assist in the locking process, reducing the need for additional complex mechanisms.
3Extent of automation
If the clip structure is modified to allow external opening, then automated locking becomes possible, but the reel structure becomes more complex
Solution Approach 1:
Instead of modifying the reel structure to allow external opening, the invention opens the clip from inside the flange in the radial direction. This approach maintains the original compact reel structure without requiring additional openings or modifications to the flange, achieving automation while preserving structural simplicity.
Solution Approach 2:
The lock jig serves multiple functions: it sandwiches the pulled-out part of the wire, pushes the tip end portion of the clip to open it, and then releases the wire to allow it to be locked by the clip. This multi-functional tool achieves automated locking without requiring structural modifications to the reel.
4Adaptability or versatility
If the lock jig operates from inside the flange, then compatibility with covered clip reels is achieved, but the locking mechanism becomes more complex
Solution Approach 1:
The lock jig is divided into a pair of tip end portions that can approach and separate from each other. This segmentation allows the lock jig to sandwich the pulled-out part of the wire and effectively push the clip from inside the flange, achieving compatibility with covered reels through a modular design.
Solution Approach 2:
The lock jig acts as an intermediary that enables the wire to interact with the clip from inside the flange. By sandwiching the pulled-out part and pushing against the clip, it mediates the locking process in a way that is compatible with covered reel structures without requiring complex modifications.

AI summary
A wire winding device includes a lock jig including a pair of tip end portions configured to approach each other or separate from each other. A control portion of the wire winding device is configured to execute: a step of winding a wire onto a winding drum; and a step of making the lock jig sandwich a pulled-out part of the wire, inserting the lock jig into a clip, and opening the tip end portions of the lock jig against biasing force of the clip to open the clip.
