Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a spiral extrusion structure is used to convey high-viscosity binder, then the binder can be conveyed, but the spiral extrusion structure will idle and cause the motor to burn out due to high viscosity
Solution Approach 1:
The patent replaces the traditional spiral extrusion mechanical conveying system with a pneumatic conveying system that uses compressed air to transport high-viscosity binder through pipelines, eliminating the idle motor problem while maintaining conveyance capability
Solution Approach 2:
The patent employs pneumatic pressure from compressed air to move the binder through the conveying system, using gas pressure instead of mechanical rotation to overcome high viscosity resistance without causing motor burnout
2Ease of operation
If heating is applied to reduce binder viscosity for smooth conveyance, then the binder can be conveyed smoothly, but the binder may denature and quality deteriorates
Solution Approach 1:
The patent changes the conveying parameter from thermal energy input to pneumatic pressure input, allowing smooth conveyance of high-viscosity binder without heating-induced denaturation and quality loss
3Productivity
If spiral extrusion structure rotates at high speed to convey binder, then conveyance efficiency improves, but shear force cuts off molecular chain and reduces viscosity
Solution Approach 1:
The patent replaces high-speed mechanical rotation with low-speed pneumatic propulsion, maintaining conveyance efficiency while eliminating excessive shear forces that would break molecular chains and alter binder composition
4Stability of the object's composition
If spiral extrusion structure is used to stir binder, then mixing occurs, but bubbles are mixed into binder and bonding performance reduces
Solution Approach 1:
The patent uses pneumatic pressure to move binder through the system without intensive stirring, achieving necessary mixing while preventing bubble entrapment that would reduce bonding performance
