Adjustable Sports Vest With Reel Tightness Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sports vests are often fixed in size, leading to issues of being too tight or too loose as the wearer's figure changes, failing to meet the fitting needs of sports personnel.
Innovation Solution
A vest with adjustable tightness featuring adjustable belts, elastic bands, and a mechanism with bevel gears and wire reels that allow for easy tightening and loosening through rotary knobs, ensuring a secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vests are made in fixed sizes, then manufacturing and inventory management are simplified, but the vests become too tight or too loose when the wearer's figure changes, resulting in poor fit
Solution Approach 1:
The vest incorporates adjustable shoulder straps with reel mechanisms that allow the wearer to dynamically adjust the tightness and length of the straps according to changes in their figure. This dynamic adjustment capability enables the vest to adapt to different body sizes and shapes, resolving the contradiction between fixed-size simplicity and adaptability to figure changes.
2Ease of operation
If adjustable mechanisms are added to vests, then the tightness can be adjusted to fit different figures, but the structure becomes more complex
Solution Approach 1:
The vest features self-adjusting reel mechanisms with rotary knobs that allow the wearer to independently adjust the shoulder strap length without assistance. The reel mechanism automatically winds and locks the adjustment belt, providing ease of operation while maintaining relatively simple structure through the use of basic mechanical components.
Solution Approach 2:
The invention replaces complex traditional adjustable mechanisms (such as multiple buckles, laces, or buttons) with a simplified reel-based mechanical system. The reel mechanism uses a rotary knob to wind an adjustment belt around a reel, providing smooth and precise adjustment with minimal components, thus improving ease of operation while controlling structural complexity.
3Productivity
If the vest uses traditional adjustment methods like buckles or laces, then the structure remains simple, but the adjustment process is inconvenient and time-consuming
Solution Approach 1:
The reel mechanism pre-positions the adjustment belt in a coiled state around the reel, ready for rapid winding. When adjustment is needed, the wearer simply rotates the knob and the belt is quickly wound to the desired length, eliminating the time-consuming process of threading laces or fumbling with multiple buckles. This preliminary preparation of the adjustment belt enables fast and convenient adjustment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient adjustment of tightness to accommodate changes in the wearer's figure, providing a better fit and enhanced stability, thus meeting the wearing requirements of sports personnel.
Implementation Method 1
two elastic bands, which are mounted on the back of the garment body, the two elastic bands are distributed in a cross manner and form an X-shape, two ends of the elastic bands are fixedly connected to one ends of the adjusting belts
Implementation Method 2
Tops of the wire reels and bottoms of the rotary knob disks are fixedly connected to bevel gears. When bottom surfaces of the rotary knob disks are in contact with top surfaces of the housings, the two bevel gears are engaged with each other
Implementation Method 3
wire reels and rotary knob disks are sleeved on the vertical rods. Adjusting ropes pass through the elastic bands, one ends of the adjusting ropes are fixedly connected to one ends of the elastic bands close to the adjusting belts, and the other ends of the adjusting ropes penetrate into the housings and are fixedly mounted on the wire reels

AI summary
Disclosed is a vest with adjustable tightness, which belongs to the technical field of clothes. The vest with adjustable tightness includes a garment body with shoulder straps and a zipper mounted, and also includes two adjusting belts, which are fixedly connected to the garment body, where the adjusting belts are erected on the shoulder straps, and two sides of a surface of the garment body are fixedly connected to mounting sheets; and two elastic bands, which are mounted on the back of the garment body, where the two elastic bands are distributed in a cross manner and form an X-shape. By rotating rotary knob disks, the elastic bands can be contracted and released, and the adjusting belts are tightened and loosened, such that sports personnel adjust tightness of the vest conveniently.
