Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a coupling device is used to connect the tank to the machine structure, then the tank can be securely blocked in position, but the complexity of the device increases

Engineering Contradiction:
Improvetank blocking reliabilityVSAvoidcoupling device complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical coupling mechanisms with a simplified system using a blocking element that engages with a cam track. The cam track converts linear motion of the blocking element into the necessary oscillating motion to engage and disengage the tank, eliminating the need for complex mechanical linkages while maintaining secure blocking.

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

Solution Approach 2:

The cam track serves as an intermediary element between the linearly moving blocking element and the tank coupling mechanism. It mediates the motion transformation, allowing a simple linear actuator to control the complex engagement and disengagement of the tank without requiring direct mechanical complexity in the coupling device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If manual coupling and decoupling operations are used, then the device structure can be simpler, but the productivity and operational efficiency decrease

Engineering Contradiction:
Improvetank coupling speedVSAvoidcoupling device complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables automatic coupling and decoupling operations where the blocking element, driven by a linear actuator, automatically engages with the cam track to secure the tank in position. This self-service mechanism eliminates manual intervention, significantly improving productivity while the cam track design keeps the overall device complexity manageable through motion transformation rather than complex control systems.

Inventive Principle:
Principle #25Self-service
