Adhesive Tape Cartridge Pigment Layer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tape cartridges struggle to effectively combine multiple pigments for achieving desired color and glittering effects without increasing the overall thickness and number of manufacturing steps.
Innovation Solution
The adhesive tape cartridge design includes a base layer, a colored layer with added pigment, and a pigment-containing adhesive layer, where each pigment is separated to prevent interference, allowing for efficient production of multiple pigment effects while maintaining a reduced tape thickness and manufacturing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two types of pigments are mixed in one layer (the bonding adhesive layer), then the manufacturing steps are reduced, but interference occurs between both pigments and the effects of the pigments cannot sufficiently be produced
Solution Approach 1:
The patent divides the adhesive tape structure into multiple layers: a base layer, a colored layer containing one type of pigment, and a bonding adhesive layer containing another type of pigment. This segmentation allows each pigment to function independently without interference, resolving the contradiction between manufacturing simplicity and pigment effect quality.
2Manufacturing precision
If two layers are newly disposed for respectively arranging the two types of pigments in the layers, then the pigment effects can be sufficiently produced, but the overall thickness of the adhesive tape and the number of manufacturing steps are increased
Solution Approach 1:
The patent merges the colored layer and bonding adhesive layer into a integrated multi-layer structure where the colored layer serves both as a color-providing layer and as part of the bonding structure. This merging allows two pigment types to be accommodated without significantly increasing overall thickness, as the layers work together rather than adding separate functional blocks.
3Manufacturing precision
If two layers are newly disposed for respectively arranging the two types of pigments in the layers, then the pigment effects can be sufficiently produced, but the number of manufacturing steps is increased
Solution Approach 1:
The patent applies preliminary action by pre-coating the base layer with a colored layer containing pigment before applying the bonding adhesive layer with another pigment. This sequential pre-preparation allows each layer to be optimized for its specific pigment type while maintaining an efficient manufacturing process that doesn't require additional complex steps.

AI summary
The disclosure discloses an adhesive tape cartridge including an adhesive tape roll. The adhesive tape roll winds an adhesive tape around a predetermined axis in a housing. The adhesive tape includes a base layer, a colored layer, and a pigment-containing adhesive layer. The colored layer is disposed on a first side of the base layer in a thickness direction and comprises a pigment added thereto. The pigment-containing adhesive layer is disposed on the first side of the colored layer in the thickness direction and comprises an adhesive to which a pigment is added.
