Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate electrical connection is provided for the further temperature sensor, then reliable temperature detection is achieved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improvetemperature detection reliabilityVSAvoidconnection structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the electrical connection for the further temperature sensor with an existing mechanical fastening component. The contact element serves dual purposes: mechanically securing the further component to the housing and simultaneously establishing electrical contact with the further temperature sensor. This merging eliminates the need for separate wiring, reducing structural complexity while maintaining reliable temperature detection.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact element is designed to perform multiple functions simultaneously: it acts as both a mechanical fastening element (securing the further component) and an electrical conductor (reading the further temperature sensor). This multi-functionality approach reduces the number of components needed and simplifies the overall device structure while ensuring reliable operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If additional wiring is added for the further temperature sensor, then temperature measurement capability is improved, but manufacturing cost increases

Engineering Contradiction:

Improvetemperature measurement capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges the electrical connection function with an existing mechanical component (the contact element). By using the same component for both mechanical fastening and electrical contact, the patent avoids adding separate wiring for the further temperature sensor, thereby maintaining temperature measurement versatility while controlling manufacturing costs.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The contact element is designed as a universal component that serves both mechanical and electrical purposes. This multi-functionality allows the device to measure additional temperature parameters without proportionally increasing manufacturing complexity or cost, as the same component structure handles both fastening and signal reading tasks.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If the further temperature sensor is positioned close to the heat-conducting plate, then assembly is simplified, but room temperature measurement accuracy deteriorates

Engineering Contradiction:

Improveassembly efficiencyVSAvoidroom temperature measurement accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The patent applies local quality by creating a thermally isolated location for the further temperature sensor within the housing. The housing structure provides thermal insulation at the specific location where the sensor is positioned, allowing the sensor to accurately measure room temperature even when the overall device is assembled close to the heat-conducting plate. This localized thermal management ensures measurement accuracy without compromising assembly efficiency.
