Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesive coverage is increased to improve peel values, then adhesion strength is improved, but manufacturing cost increases
Solution Approach 1:
The adhesive is segmented into discrete diamond-shaped patches rather than applying continuous adhesive coverage. This segmentation allows the adhesive to be concentrated in high-value areas where it provides maximum peeling resistance, while eliminating waste in areas where adhesive is unnecessary. The segmented approach directly reduces total adhesive quantity while maintaining or improving overall peel values.
Solution Approach 2:
The invention applies adhesive with varying local quality through diamond-shaped patches of different sizes and configurations. Larger diamond patches provide stronger localized adhesion where high peel resistance is needed, while smaller or absent patches reduce adhesive usage in areas where full coverage is unnecessary. This local differentiation optimizes the balance between peel value and adhesive quantity.
2Quantity of substance
If adhesive coverage is reduced to minimize cost, then manufacturing cost is reduced, but peel values decrease
Solution Approach 1:
By segmenting the adhesive into strategic diamond-shaped patches, the invention maintains effective peel values with reduced total adhesive coverage. The segmentation ensures adhesive is placed only where it contributes to peeling resistance, eliminating waste and achieving cost reduction without sacrificing performance.
Solution Approach 2:
The invention changes the parameters of adhesive application by specifying diamond-shaped geometries with particular size ranges, spacing, and patterns. These parameter changes optimize the distribution of adhesive to achieve maximum peel value per unit of adhesive, allowing reduced coverage while maintaining strength.
3Area of stationary object
If flood coating is used to ensure complete coverage, then adhesive coverage is maximized, but manufacturing cost increases
Solution Approach 1:
The flood coating approach is replaced with segmented diamond-shaped patches that cover only the necessary areas. This segmentation eliminates the waste inherent in flood coating while ensuring complete coverage of high-value regions, thereby reducing adhesive quantity without sacrificing coverage effectiveness.
Solution Approach 2:
The invention extracts the unnecessary portions of adhesive coverage that would be applied in flood coating, retaining only the essential diamond-shaped patches needed for effective peeling. This extraction removes waste material while preserving the functional coverage area.
4Quantity of substance
If irregular adhesive patterns are used to reduce adhesive usage, then adhesive quantity is reduced, but consistency in printer performance decreases
Solution Approach 1:
The invention establishes specific parameters for the diamond-shaped adhesive patches including size ranges, spacing, and geometric configuration. These controlled parameters ensure consistent pressure distribution on printer rollers while maintaining reduced adhesive usage. The regularity of the diamond pattern provides predictability for printer operation.
Solution Approach 2:
While maintaining overall pattern regularity, the diamond shape introduces a specific asymmetric geometry that optimizes pressure distribution. The diamond orientation and shape create consistent contact points with printer rollers, ensuring reliable performance while using less adhesive than conventional patterns.
