Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If high-expansion agents are used to achieve desired bossed-recessed shapes, then the design properties and shape control are improved, but the manufacturing precision and cost control deteriorate
Solution Approach 1:
The patent applies local quality by using a volume expansion suppressor that is applied selectively to specific regions of the volume expansion layer. This allows different regions to have different degrees of volume expansion, enabling precise control over the bossed-recessed shape formation. The suppressor is applied in amounts corresponding to the desired degree of volume expansion suppression in each region.
Solution Approach 2:
The patent utilizes parameter changes by controlling the amount of volume expansion suppressor applied to different regions. By varying the amount of suppressor applied, the degree of volume expansion can be precisely controlled. The suppressor amount is adjusted based on the desired bossed-recessed shape characteristics for each region.
2Adaptability or versatility
If conventional printing methods are used for small-lot production, then the production flexibility is improved, but the manufacturing cost increases
Solution Approach 1:
The patent replaces conventional mechanical printing methods with an inkjet printing system. This substitution enables precise digital control of the volume expansion suppressor application, allowing for flexible small-lot production with reduced material waste and lower operational costs compared to traditional mechanical embossing methods.
Solution Approach 2:
The inkjet printing method allows for continuous adjustment of the volume expansion suppressor discharge amount based on digital data. This parameter control enables cost-effective small-lot production by applying the suppressor only where and how much is needed, avoiding the high costs associated with conventional methods for small quantities.
3Device complexity
If the volume expansion suppressor is applied uniformly, then the manufacturing process is simplified, but the design properties and shape variation are reduced
Solution Approach 1:
The patent implements local quality by applying the volume expansion suppressor non-uniformly across different regions. The application amount is varied according to the desired degree of volume expansion suppression in each region, enabling diverse bossed-recessed shape variations while maintaining a systematic application process through inkjet technology.
