Problem
Conventional wire winding devices face challenges in assembling convenience and productivity due to complex fastening structures, which hinder easy manufacturing and lead to interference issues when fastening wires.
Innovation Solution
A wire winding adjusting device with a reel part and housing part that includes a cylindrical winding body with a receiving groove, fastening grooves, and flange parts with slots and coupling holes, allowing for secure wire fastening without increasing the thickness of the winding body, and a central partition wall to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If both end portions of the wire are forcibly fit into a coupling hole formed in the winding member, then the wire can be fastened to the winding member, but if the size of the coupling hole exceeds twice the cross-sectional area of the wire, the wire cannot be firmly joined to the winding member, and productivity is deteriorated due to varying hole sizes for different wire diameters
Solution Approach 1:
The invention divides the single coupling hole into multiple coupling holes (first coupling hole and second coupling hole) arranged in the circumferential direction. This segmentation allows the wire to be fastened through multiple smaller holes rather than one large hole, maintaining fastening strength while enabling standardized hole sizes that improve manufacturing productivity.
Solution Approach 2:
The multiple coupling holes are designed with standardized dimensions that can accommodate wires of different diameters. This universal design allows the same winding member structure to be used for various wire sizes, eliminating the need to change coupling hole sizes and thereby improving productivity.
2Reliability
If the winding member is divided or is fastened through a separate fastening part, then the wire can be secured, but the shape of a mold becomes complicated, and the number of assembling processes and assembly time are increased, thereby reducing productivity and economic feasibility
Solution Approach 1:
The invention merges the coupling hole function and the fastening function into a single integrated structure. The multiple coupling holes are formed directly in the winding member body, eliminating the need for separate fastening parts or complex divided structures, thereby simplifying the mold shape and reducing assembly complexity while maintaining fastening reliability.
3Volume of moving object
If wires are fastened in a narrow space of the outer circumference in a rotationally symmetrical form, then the structure is compact, but the central portion cannot be utilized as fastening space, limiting design flexibility
Solution Approach 1:
The invention transitions from a single-plane rotational symmetry arrangement to a multi-dimensional arrangement by placing coupling holes in the circumferential direction at different angular positions. This dimensional change allows the central portion to remain available while utilizing the outer circumference space effectively, increasing both volume utilization and design flexibility.

AI summary
In order to improve assembling convenience and productivity of products, the present invention provides a wire winding adjusting device comprising a reel portion which is accommodated in a housing unit and is selectively hook-engaged with and rotated interlocking with a rotation manipulation means such that a wire is wound on the outer circumference thereof, wherein the rotation manipulation means is rotated about a driving protrusion at the center thereof during a rotation manipulation. The reel portion comprises: a winding body unit which has a cylindrical shape, has an accommodation groove formed in an upper surface side thereof such that an end portion of the driving protrusion is accommodated in the accommodation groove and a lower surface side which is dented to form a coupling groove portion, and includes a wire tying unit adjacent to the bottom surface of the coupling groove unit and having a first tying hole and a second tying hole through which the wire partially passes and which are formed through the wire tying unit to be apart from each other such that the wire is tied; and a pair of flange portions which expand and protrude outward in the radial direction along upper and lower boundaries of the outer circumferential surface of the winding body unit such that a wire winding groove can be formed between inner surfaces thereof facing each other, and which have a through-slot groove that is open because the first tying hole and the second tying hole are apart from each other along the circumferential direction such that an end portion of the wire pulled into the coupling groove unit can be pressed by a part of the wire.
