Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If harnesses are installed along robotic arms to supply electric power to the valve manifold, then continuous power supply is achieved, but the movable range is limited and entanglement occurs

Engineering Contradiction:
Improvecontinuous power supplyVSAvoidmovable range
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The invention extracts the power supply system from the external harness configuration and relocates it to a self-contained battery unit mounted on the end effector. This extraction eliminates the physical constraint of harnesses, allowing the robotic arm to move freely without entanglement while maintaining continuous power supply to the valve manifold through the onboard battery.

Inventive Principle:
Principle #2Taking out (Extraction)

2Use of energy by moving object

If the valve manifold includes a large number of valves and the end effector is equipped with a battery, then the valve manifold can be powered, but the size and weight of the battery increase

Engineering Contradiction:
Improvepower supply capabilityVSAvoidbattery weight
Core Design Contradiction:
Use of energy by moving objectVSWeight of moving object

Solution Approach 1:

The invention implements a feeding station that performs preliminary charging actions on the battery-mounted valve manifold. The feeding station wirelessly transmits electric energy to charge the battery before the robotic arm executes tasks requiring the valve manifold. This preliminary charging approach allows the battery to be recharged externally rather than requiring large capacity from the start, thus reducing battery weight and size while ensuring sufficient power availability during operation.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the valve manifold is moved by a movable unit, then flexibility is improved, but stable movement and continuous operation become difficult without external power connection

Engineering Contradiction:
ImprovemovabilityVSAvoidcontinuous operation stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The invention enables the valve manifold to serve itself by mounting the battery directly on the end effector, making the power supply system self-contained and portable. The battery provides autonomous power without requiring external harness connections, allowing the movable unit to move freely while maintaining reliable and continuous operation of the valve manifold. The system achieves both movability and operational stability through this self-service power configuration.

Inventive Principle:
Principle #25Self-service
