Wristband Adhesive Winding Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wristbands are cumbersome to wind around wrists or ankles of varying sizes, often resulting in improper form and reduced workability, especially when users attempt to adhere both ends alone, and they require time-consuming preparation to expose adhesive layers.
Innovation Solution
The method involves adhering the rear surfaces of both ends of the wristband first, followed by a two-step process to form a ring shape, using guides for accurate adhesion and eliminating the need to peel off a mount to expose the adhesive layer, allowing for easy and accurate winding around different sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wristband is provided in an elongate strip shape requiring the user to wind it around the wrist, then the wristband can be customized to fit different users, but the operation becomes cumbersome and workability is reduced
Solution Approach 1:
The wristband is pre-formed into a ring shape with adhesive portions positioned before use. The guides are pre-attached to indicate adhesion positions, eliminating the need for users to measure and position the wristband manually during application.
Solution Approach 2:
The wristband is divided into functional regions: a non-adhesive ring portion that forms the wearable band, and separate adhesive portions at the ends. This segmentation allows the band to be pre-formed while keeping adhesion as a distinct, simplified step.
2Reliability
If both ends of the wristband are adhered to each other to form a ring, then the wristband can be properly secured, but both ends are easily shifted from each other during adhesion
Solution Approach 1:
Guides are introduced as intermediary elements attached to the wristband. These guides extend beyond the adhesive portions and serve as alignment markers that facilitate accurate positioning of adhesive ends against each other during the adhesion process.
Solution Approach 2:
The guides are pre-attached to the wristband at specific positions relative to the adhesive portions. This preliminary positioning ensures that when the guides are aligned during application, the adhesive portions will automatically align correctly, maintaining precision without requiring manual measurement.
3Reliability
If the wristband is provided as a continuous body requiring peeling of mount to expose adhesive layer, then the adhesive is protected during storage and transport, but preparation time is increased
Solution Approach 1:
The mount is pre-removed from the adhesive portions during manufacturing, exposing the adhesive layers before the product reaches the user. This preliminary action eliminates the need for users to perform the time-consuming peeling operation during preparation.
Solution Approach 2:
The protective mount is completely removed from the adhesive portions in the manufacturing process, extracting the protective function to the manufacturing stage rather than requiring it during use. This allows the adhesive to remain protected during storage through alternative means while being immediately ready for application.
4Device complexity
If the wristband is made in a label shape with both ends adhered, then the structure is simplified, but the notch portion cannot sufficiently fulfill its function if ends are not accurately adhered
Solution Approach 1:
Guides are introduced as intermediary alignment markers that ensure the adhesive portions are accurately positioned relative to each other during adhesion. This maintains the reliability of the notch function by preventing misalignment, while the overall structure remains simplified as a label-shaped wristband.
Solution Approach 2:
The guides are pre-attached at specific positions that correspond to the notch location and adhesive portions. This preliminary positioning ensures that when guides are aligned during application, the notch will be correctly positioned and functional, even in the simplified label structure.

Function Achieved in This Case
This approach simplifies the winding process, ensuring a proper ring shape can be formed easily and accurately, even by one person, and reduces preparation time by allowing immediate adhesion after the mount is removed.

AI summary
The present invention relates to a method for winding a belt-shaped band (1A) around a subject (W), comprising defining a remaining exposed part of an exposed adhesive layer (3) located on a rear surface of a first portion (6) of a belt-shaped band by adhering a rear surface of a second portion (7) of the belt-shaped band to the exposed adhesive layer; and adjusting a diameter of the belt-shaped band by selectively affixing the remaining exposed part of the adhesive layer (3) to an arbitrary position of a front surface (10) of the belt-shaped band. Moreover, the present invention refers to a band comprising a belt-shaped body (1A) having opposing first (6) and second (7) portions in a longitudinal direction; and an adhesive layer (3) located on a rear surface of the first portion of the belt-shape body, wherein a part of the adhesive layer (3) is configured to remain exposed when a rear surface of the second portion is adhered to the adhesive layer such that a remaining exposed part of the adhesive layer (3) is selectively adherable to an arbitrary position of a front surface (10) of the belt-shaped body such that a diameter of the band is adjustable.
