Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cooling pumps use additional motors to power the pumps, then the cooling function is achieved, but energy consumption increases and cost increases

Engineering Contradiction:
Improvecooling functionVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent combines the cooling pump function with the existing motor-driven spindle system. The motor that already drives the spindle also drives the cooling pump through a shared transmission mechanism (belt or gear), eliminating the need for a separate motor. This merging of functions resolves the contradiction by achieving cooling without additional energy consumption from a separate motor.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single motor is designed to perform multiple functions: driving the spindle for machining operations and simultaneously driving the cooling pump for coolant circulation. This multi-functionality allows the system to achieve reliable cooling while avoiding the energy waste and cost increase associated with dedicated single-function motors.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If conventional cooling pumps equip additional motors, then the cooling pump can operate independently, but device complexity and cost increase

Engineering Contradiction:
Improveindependent operationVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cooling pump is integrated with the existing motor and transmission system rather than being a separate independently-powered unit. The pump operates through the shared transmission mechanism, reducing system complexity while maintaining operational effectiveness through the unified drive system.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional cooling pumps use separate motors, then the cooling system is independent, but purchasing cost increases

Engineering Contradiction:
Improvecooling system independenceVSAvoidpurchasing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By merging the cooling pump drive with the existing spindle motor, the system eliminates the need to purchase and install an additional motor. The integrated design reduces purchasing costs while maintaining cooling reliability through the shared transmission mechanism that ensures the pump operates whenever the spindle is running.

Inventive Principle:
Principle #5Merging (Combining)
