Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional temperature control equipment is used to maintain constant temperature environment, then temperature stability is improved, but cost and energy consumption increase significantly

Engineering Contradiction:
Improvetemperature stabilityVSAvoidenergy consumption
Core Design Contradiction:
TemperatureVSUse of energy by stationary object

Solution Approach 1:

The temperature control system is divided into multiple independent temperature equalizers that can be selectively activated. Each equalizer handles a specific zone or component, allowing energy-efficient partial operation rather than full-system operation, thus reducing overall energy consumption while maintaining temperature stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The temperature equalizers utilize the thermal characteristics of the object being controlled (such as heat generation from electronic components or thermal mass of machine parts) to automatically regulate temperature. The system leverages the object's own thermal properties and the phase change characteristics of heat transfer fluid to maintain temperature without requiring continuous external energy input.

Inventive Principle:
Principle #25Self-service

2Temperature

If conventional temperature control equipment is used to maintain constant temperature environment, then temperature stability is improved, but device complexity and cost increase

Engineering Contradiction:
Improvetemperature stabilityVSAvoidsystem complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The temperature equalizers serve multiple functions: they act as heat exchangers, temperature regulators, and thermal buffers simultaneously. The same component structure is used for both heating and cooling operations by simply reversing the heat transfer fluid flow direction, eliminating the need for separate heating and cooling systems and reducing overall device complexity.

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

Solution Approach 2:

The system controls temperature by changing the flow rate and direction of the heat transfer fluid through the equalizers, rather than using complex mechanical adjustments. By varying fluid parameters (flow rate, temperature, direction), the system achieves precise temperature control with simple actuators, reducing mechanical complexity.

Inventive Principle:
Principle #35Parameter changes

3Temperature

If heat transfer fluid flows through fluid channels, then temperature equalizing heat transfer is improved, but fluid leakage risk increases

Engineering Contradiction:
Improvetemperature equalizing efficiencyVSAvoidfluid leakage prevention
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The fluid channels are nested within the solid structure of the temperature equalizers, with the channels formed as cavities or passages inside the equalizer bodies. This nested design eliminates external piping connections that are prone to leakage, as the fluid is contained entirely within the solid structure during operation.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent uses standardized, modular temperature equalizer designs with replicated fluid channel patterns. These standardized components can be manufactured with high precision using modern manufacturing techniques, ensuring consistent sealing surfaces and reducing leakage risks through improved manufacturing quality rather than complex sealing mechanisms.

Inventive Principle:
Principle #26Copying
