Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If electrical power is supplied via a power cable or pneumatic power via a pneumatic conduit, then the tool can operate, but the presence of cables or hoses constitutes a problem in terms of space and safety

Engineering Contradiction:
Improvepower supplyVSAvoidsafety and space
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the power supply cables and pneumatic hoses from the system by implementing a battery-powered design. The battery is integrated into the tool body, eliminating external power connections and thereby removing the safety and space constraints imposed by cables and hoses.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical pneumatic power transmission system with an electrical system powered by a battery. This substitution eliminates the need for pneumatic conduits and associated hardware, simplifying the tool's structure and improving safety.

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

2Reliability

If the tool is specifically made for a specific type or size of hose clamps, then it can perform the clamping function, but it cannot be used to mount hose clamps of different types or sizes

Engineering Contradiction:
Improveclamping functionVSAvoidclamp type compatibility
Core Design Contradiction:
