Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional probe cleaning cloth is formed by stacking and adhering different materials layers with glue through baking, heating, and cooling process, then the cleaning cloth can be produced, but the thermal expansion and contraction causes concave and curled shapes with air bubbles forming
Solution Approach 1:
The patent changes the bonding method from thermal adhesive bonding to ultrasonic bonding, fundamentally altering the process parameters to eliminate thermal expansion and contraction issues. This parameter change resolves the contradiction by enabling production without the harmful thermal effects that cause concave and curled shapes.
Solution Approach 2:
The patent replaces the thermal bonding system (adhesive + heating) with an ultrasonic bonding system that uses mechanical vibration energy. This substitution eliminates the thermal expansion and contraction problem while achieving effective layer bonding, thus resolving the flatness issue.
2Ease of operation
If conventional probe cleaning cloth uses hard materials for cleaning, then cleaning capability is improved, but the materials are easily damaged
Solution Approach 1:
The patent uses composite materials combining polyester fiber base fabric with embedded abrasive particles (alumina or silicon carbide). This composite structure provides both the hardness needed for cleaning capability and the durability of the polyester base, resolving the contradiction between cleaning effectiveness and material durability.
Solution Approach 2:
The patent applies abrasive particles only to the surface layer where cleaning action is needed, while the base fabric maintains its durability. This local quality differentiation allows the cleaning surface to be hard and effective while the overall structure remains durable and resistant to damage.
3Ease of manufacture
If conventional probe cleaning cloth production follows traditional stacking and adhering process, then production can proceed, but the process is very time-consuming and labor-intensive
Solution Approach 1:
The patent merges multiple production steps into a more integrated process using ultrasonic bonding. By combining layer stacking and bonding into a single ultrasonic processing step, the patent eliminates separate adhesive application, baking, and cooling steps, thereby significantly reducing production time and increasing productivity.
4Strength
If conventional probe cleaning cloth undergoes baking, heating, and cooling process, then adhesive bonding is achieved, but thermal expansion and contraction cause concave and curled shapes
Solution Approach 1:
The patent replaces thermal bonding with ultrasonic bonding, substituting a mechanical vibration-based system for the thermal system. This substitution achieves strong bonding between layers without subjecting the materials to thermal expansion and contraction, thereby maintaining flatness while ensuring bonding strength.
