Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If temperature sensors are stuck onto the terminal block, then temperature monitoring is achieved, but the temperature sensor may detach and stability is compromised

Engineering Contradiction:
Improvetemperature sensor stabilityVSAvoidterminal block structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The terminal block incorporates accommodating grooves at specific locations where temperature sensors need to be mounted. These grooves provide localized structural features that enhance sensor fixation without altering the entire terminal block structure, thereby improving reliability while maintaining simplicity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The temperature sensor is nested within the accommodating groove of the terminal block. This nesting arrangement allows the sensor to be securely housed within the groove structure, increasing contact surfaces and preventing detachment while maintaining a compact integrated design.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If accommodating grooves are added to the terminal block, then temperature sensor fixation is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvetemperature sensor fixationVSAvoidterminal block manufacturing
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The accommodating grooves are pre-formed as integral features of the terminal block during the molding process. This preliminary action ensures that the grooves are already in place before sensor installation, eliminating the need for additional machining or assembly steps, thus maintaining ease of manufacture while improving sensor fixation.

Inventive Principle:
Principle #10Preliminary action
