Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If rubber water outlet nozzles with fine-holes are used, then the descaling and drizzling outlet water effect is achieved, but the nozzle deformation under water pressure causes unstable outlet water shape
Solution Approach 1:
The extension part is nested inside the hollow cavity of the nozzle part, forming a nested structure where the extension part's outer wall surface and the nozzle part's inner wall surface cooperate to form the water jet channel. This nested arrangement provides structural support to the nozzle bottom while maintaining the desired outlet effect.
Solution Approach 2:
The invention uses different materials with different hardness values - the nozzle part is made of softer rubber material (hardness 30-70 Shore A) for flexibility and descaling, while the extension part is made of harder material (hardness 80-95 Shore A) for structural support. This composite material approach allows each component to fulfill its specific function while resolving the contradiction between softness for outlet effect and hardness for dimensional stability.
2Ease of operation
If soft rubber material is used for the nozzle, then the descaling effect is improved, but the nozzle part deforms under water pressure causing unstable outlet water shape
Solution Approach 1:
The invention applies different material properties to different parts of the system - the nozzle part uses soft rubber material (hardness 30-70 Shore A) for flexibility and descaling functionality, while the extension part uses hard material (hardness 80-95 Shore A) for structural support and dimensional stability. This local differentiation of material quality allows each component to optimize its specific function.
Solution Approach 2:
The extension part acts as an intermediary structural element between the water supply and the soft nozzle part. It provides a rigid framework that supports the soft rubber nozzle, preventing excessive deformation under water pressure while allowing the nozzle to maintain its flexibility for descaling.
3Adaptability or versatility
If the nozzle part is made of soft material, then flexibility is improved, but the bottom water outlet hole expansion deformation becomes unstable
Solution Approach 1:
The invention applies different material properties to different parts of the system - the nozzle part uses soft rubber material (hardness 30-70 Shore A) for flexibility and descaling functionality, while the extension part uses hard material (hardness 80-95 Shore A) for structural support and dimensional stability. This local differentiation of material quality allows each component to optimize its specific function.
Solution Approach 2:
The extension part is nested inside the hollow cavity of the nozzle part, forming a nested structure where the extension part's outer wall surface and the nozzle part's inner wall surface cooperate to form the water jet channel. This nested arrangement provides structural support to the nozzle bottom while maintaining the desired outlet effect.
