Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If heat treatment or physical processing is applied to fabric before printing to improve texture, then fabric texture is improved, but processing complexity increases
Solution Approach 1:
The fabric surface is pre-treated by ejecting liquid through a nozzle with specific diameter ratio (5≤D/d≤150) to create micro-irregularities before printing, preparing the surface for better ink adhesion and texture without requiring complex post-processing equipment
Solution Approach 2:
The invention changes the physical parameters of liquid ejection by controlling the nozzle diameter ratio (D/d) within a specific range (5≤D/d≤150) and ejecting velocity to create optimal surface irregularities that improve fabric texture and printing quality simultaneously
2Manufacturing precision
If liquid is ejected at high velocity to create surface irregularities, then fabric texture improves, but liquid consumption increases
Solution Approach 1:
By optimizing the nozzle diameter ratio (D/d) within 5≤D/d≤150 and controlling ejection velocity, the invention achieves effective surface irregularity creation with minimal liquid consumption, preventing excessive liquid use while maintaining texture improvement
Solution Approach 2:
The liquid ejection creates localized micro-irregularities only where needed on the fabric surface through controlled partial action, rather than requiring excessive liquid coverage, thus improving texture efficiently with reduced liquid consumption
