Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If rigid regulators are used to control discharge flow rate, then thickness regulation is achieved, but stepped height difference is generated between adjacent regulators
Solution Approach 1:
The patent employs a flexible regulator instead of a rigid one. The flexible regulator can deform smoothly between adjacent driving pieces, allowing the coating material to flow uniformly without creating stepped height differences. This flexibility enables the regulator to adapt to position variations while maintaining coating thickness uniformity and surface smoothness.
2Adaptability or versatility
If multiple regulators are arranged along the first direction, then thickness regulation range is increased, but height difference between regulators increases
Solution Approach 1:
By using a flexible regulator that can deform between adjacent driving pieces, the system achieves both extended regulation range and maintained thickness uniformity. The flexibility allows each regulator to independently adjust to its position while maintaining consistent coating thickness across multiple regulators arranged along the first direction.
3Shape
If regulator is made flexible to prevent stepped height difference, then coating smoothness is improved, but regulator structure complexity increases
Solution Approach 1:
The flexible regulator uses a simple flexible member structure that can deform smoothly. This straightforward implementation achieves coating surface smoothness without introducing complex mechanisms, as the flexibility itself is the key feature rather than a complex structural system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents stepped height differences, ensuring a smooth coating transition and improving the overall coating effect by regulating thickness uniformly.
Implementation Method 1
the regulator in this solution is a flexible member. Thus, when the driving pieces are driving the regulator to move, the regulator can well deform due to its flexibility, so that the regulator can form a smooth transitional shape in a region between the corresponding two adjacent driving pieces
