Adhesive Sheet with Removable Cutouts for Badge Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching badges to garments, such as sewing or using pre-attached adhesive badges, are time-consuming, damage the clothing or badges when removed, and are more expensive and difficult to store and modify.
Innovation Solution
An adhesive sheet with a backing, an adhesive layer, and a protective layer featuring removable cutouts matching the badge shape, along with markings for identification, allows for easy application and removal of badges using heat-setting or solvent-dissolvable adhesives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If badges are sewn onto garments, then the attachment is secure and reusable, but the process is time-consuming and can damage the clothing and/or badge when removed
Solution Approach 1:
The patent replaces the mechanical sewing process with a thermal adhesive bonding system. The adhesive sheet contains a heat-settable adhesive layer that bonds the badge to the garment through heat application (e.g., ironing), eliminating the need for needles, threads, and manual sewing operations while maintaining secure attachment and enabling easy removal without damage.
Solution Approach 2:
The patent utilizes temperature parameter changes to control the adhesive bonding process. The adhesive layer transitions from a soft, bondable state at lower temperatures to a set, secure state at elevated temperatures during application, and can be reversed by cooling or solvent exposure for removal, providing both secure attachment and easy detachment without damage.
2Ease of operation
If pre-attached adhesive is used on badges, then application is simplified, but the badges are more expensive and more difficult to store and modify
Solution Approach 1:
The patent separates the adhesive function from the badge itself by using a standalone adhesive sheet with removable cutouts. This allows the badge to remain simple and inexpensive while the adhesive sheet provides the bonding capability. The segmented design enables easy storage of multiple badges without adhesive attachment and allows modification of badges without dealing with pre-attached adhesive layers.
Solution Approach 2:
The adhesive sheet acts as an intermediary between the badge and the garment. Instead of attaching adhesive directly to the badge (which complicates storage and modification), the sheet serves as a separate bonding medium that can be applied to the garment surface, allowing the badge to be applied and removed independently without permanent adhesive attachment.
3Ease of operation
If a protective layer with removable cutouts is used, then badge application is facilitated and alignment is improved, but the structure becomes more complex
Solution Approach 1:
The protective layer is pre-formed with removable cutouts that match the badge shape before application. This preliminary preparation guides the user in properly aligning the badge with the adhesive area, ensuring correct positioning without requiring complex alignment procedures during application. The pre-cut configuration simplifies the overall application process despite adding structural layers.

AI summary
An adhesive sheet (10) for use in affixing a badge to a garment comprises a plurality of cutouts (18, 20, 22, 24), each cutout having a shape (19, 21, 23, 25) that approximately matches a shape of a badge.
