Adhesive Tape Cartridge Pigment Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In adhesive tape cartridges, the intermixture of multiple pigments in a single layer leads to interference, preventing them from fully exerting their respective effects and affecting the bonding performance and color representation.
Innovation Solution
The adhesive tape cartridge features a layered structure with a first adhesive layer containing a first pigment and a second adhesive layer containing a second pigment, where the volume ratio of the second pigment is smaller than the first, allowing them to be distributed in separate layers to minimize interference and enhance their individual effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pigments are added to a single adhesive layer, then color variety is improved, but pigment interference occurs and bonding performance deteriorates
Solution Approach 1:
The adhesive tape is divided into multiple adhesive layers (first adhesive layer and second adhesive layer), with each layer containing a different pigment. This segmentation prevents pigment interference while maintaining color variety, as each pigment is confined to its own layer and can fully exert its effect without interfering with other pigments.
Solution Approach 2:
The solution transitions from a single-layer structure to a multi-layer structure in the thickness direction. By adding the dimension of layering, the patent enables multiple pigments to coexist without interference, as they are separated in the vertical dimension rather than mixed in the same plane.
2Manufacturing precision
If multiple pigments are added to a single adhesive layer, then color representation is improved, but pigment interference prevents full effect and manufacturing complexity increases
Solution Approach 1:
The adhesive tape is segmented into multiple adhesive layers, each dedicated to a specific pigment. This segmentation improves color representation by allowing each pigment to be optimized independently in its own layer, while the overall structure remains relatively simple with layers stacked in the thickness direction.
3Manufacturing precision
If pigment volume ratio is increased to enhance color effect, then color intensity is improved, but bonding performance deteriorates
Solution Approach 1:
By segmenting the adhesive tape into multiple layers with different pigments, each layer can have an optimized pigment volume ratio for maximum color intensity without compromising bonding performance. The total adhesive material is distributed across layers, maintaining overall bonding effectiveness.
Solution Approach 2:
Each adhesive layer is given local quality with a specific pigment type and optimized volume ratio suited for its intended color effect. This allows high pigment concentration in each layer for intense color while the distributed structure across multiple layers preserves overall bonding performance.
