Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the sealed liquid bag is tilted by mechanical structure to discharge viscous liquid, then the discharge efficiency is improved, but the operation time is increased and the device complexity is increased

Engineering Contradiction:
Improvedischarge efficiencyVSAvoidoperation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical tilting structure with a squeezing mechanism that uses rollers to compress the liquid bag directly. This substitution eliminates the need for complex mechanical tilting while achieving efficient discharge through localized compression forces applied to the bag material.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts the essential function of discharge from the complex mechanical tilting system and implements it through a simpler squeezing action. By focusing on the core mechanism of forcing liquid out through compression rather than gravitational tilting, the system achieves the same goal with reduced complexity and time.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If the liquid bag is hanged and squeezed by complex squeezing device, then the discharge is improved, but the device complexity and cost are increased

Engineering Contradiction:
Improvedischarge efficiencyVSAvoidsqueezing device complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces complex hanging and squeezing mechanisms with a direct roller-based squeezing system. The rollers apply compression force directly to the liquid bag, eliminating the need for hanging structures and complex mechanical linkages while maintaining effective discharge capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention utilizes the flexibility of the liquid bag itself as part of the squeezing mechanism. The bag's flexible material allows it to be compressed by the rollers and conform to the squeezing force, eliminating the need for rigid hanging structures and complex mechanical support systems.

Inventive Principle:

Solution Approach 1:

The invention extracts the squeezing function from the expensive assisted gas bag system and implements it through a simpler mechanical roller mechanism. By removing the gas charging infrastructure and associated costs, the system achieves the same discharge effect through direct mechanical compression.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a simple, inexpensive roller-based squeezing mechanism that can be easily manufactured and replaced if needed, compared to the expensive and complex gas bag system. The rollers provide a cost-effective solution that achieves the same functional result without requiring gas charging infrastructure.
