Solution Overview

Problem

Conventional temperature adjustment mechanisms for electronic components face difficulties in effectively increasing or decreasing temperatures due to exposure to external air, leading to issues like dew condensation and temperature instability.

Innovation Solution

A contactor with a temperature adjustment mechanism and a cover that uses a shielding mechanism, such as an air curtain or iris diaphragm, to prevent external air effects, allowing for precise temperature control by adjusting the distance between the aperture and contact portions and supplying dry air to maintain a stable internal environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the temperature adjustment mechanism is exposed to external air for component replacement, then ease of operation is improved, but temperature stability deteriorates due to heat exchange with external air

Engineering Contradiction:

Improveease of component replacementVSAvoidtemperature stability

Core Design Contradiction:

Ease of operationVSTemperature

Solution Approach 1:

The cover is opened in advance before component replacement, and the temperature adjustment mechanism is preheated or pre-cooled to the target temperature. This preliminary action ensures that when the component is replaced and the cover is closed, the temperature environment is already stabilized, preventing temperature fluctuations during the operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A shield structure is introduced as an intermediary element between the temperature adjustment mechanism and the external air. The shield can be selectively positioned to isolate the temperature adjustment mechanism from external air while allowing easy access for component replacement, thus maintaining temperature stability without compromising operational ease.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the temperature adjustment mechanism is exposed to external air, then ease of operation is improved, but harmful effects from external air increase such as dew condensation

Engineering Contradiction:

Improveease of component replacementVSAvoiddew condensation and contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cover is opened beforehand to allow component replacement, and the temperature adjustment mechanism is pre-conditioned to the appropriate temperature before the cover is closed. This preliminary action prevents dew condensation by ensuring the surface temperature remains above the dew point throughout the operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A shield structure serves as an intermediary barrier that protects the temperature adjustment mechanism from direct exposure to external air containing moisture and contaminants. The shield can be opened for component replacement and closed during temperature adjustment, eliminating harmful effects while maintaining operational ease.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the cover is opened for component replacement, then ease of operation is improved, but temperature control precision deteriorates due to external air interference

Engineering Contradiction:

Improveease of component replacementVSAvoidtemperature control precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The cover is opened in advance before component replacement, and the temperature adjustment mechanism is pre-adjusted to the precise target temperature. This preliminary action allows the temperature to be stabilized before external air exposure, minimizing the impact on temperature control precision when the cover is subsequently closed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A shield structure is introduced as an intermediary element that can be selectively positioned. When closed, it maintains precise temperature control by isolating the temperature adjustment mechanism from external air. When opened, it allows easy component replacement. This mediator enables both precise temperature control and operational ease at different times.

Inventive Principle:

Principle #24Intermediary (Mediator)
