Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a pressing device is used to press chips during testing, then electrical connection is ensured, but chips adhere to the pressing device after testing

Engineering Contradiction:

Improveelectrical connectionVSAvoidchip adherence

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The pressing device is divided into multiple movable members (pushing blocks) that can independently move relative to the contacting structure. This segmentation allows the pressing function to be separated from the releasing function, enabling chips to be pushed away after testing without manual intervention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pressing device transitions from a static pressing structure to a dynamic one where movable members can change position. The movable members move from an initial position (pressing chips against the contacting structure) to a second position (pushing chips away), enabling automatic separation without adherence.

Inventive Principle:

Principle #15Dynamics

2Object-generated harmful factors

If manual separation of chips from pressing device is performed, then adherence issue is resolved, but testing operation is delayed and chips are prone to damage

Engineering Contradiction:

Improveadherence resolutionVSAvoidtesting operation time

Core Design Contradiction:

Object-generated harmful factorsVSLoss of time

Solution Approach 1:

The movable members are pre-positioned to automatically push chips away after testing completes. This preliminary positioning eliminates the need for manual separation operations, preventing time loss and potential damage before the separation action is even needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The pressing device performs its own separation function through the movable members that automatically push chips away after testing. The system serves itself by eliminating the need for external manual intervention, thereby preventing time loss and operational delays.

Inventive Principle:

Principle #25Self-service

3Object-generated harmful factors

If manual separation of chips from pressing device is performed, then adherence issue is resolved, but chips are prone to damage from improper operation

Engineering Contradiction:

Improveadherence resolutionVSAvoidchip damage

Core Design Contradiction:

Object-generated harmful factorsVSObject-affected harmful factors

Solution Approach 1:

The manual mechanical separation operation is replaced with an automated mechanical system where movable members are actuated by the environment control device. This substitution eliminates human error and improper operation, preventing chip damage while resolving the adherence issue.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If pressing device maintains constant contact with chips, then electrical connection is stable, but chip separation becomes difficult

Engineering Contradiction:

Improveelectrical connection stabilityVSAvoidchip separation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The pressing device uses dynamic movable members that can change their position and contact state. During testing, members maintain contact for stable electrical connection; after testing, members move to push chips away, making separation easy without manual intervention.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The pressing device operates in periodic cycles: pressing phase (maintaining contact for testing) followed by separation phase (movable members push chips away). This periodic action alternates between stable contact and easy separation, resolving the contradiction between connection stability and separation ease.

Inventive Principle:

Principle #19Periodic action

AI summary

A chip testing system and an environment control apparatus are provided. The chip testing system includes the environment control apparatus, a central control device, and a chip testing device. The environment control apparatus includes an apparatus body and a pressing device. When the chip testing device is disposed in an accommodating chamber of the apparatus body, and the central control device controls the pressing device to press a plurality of side surfaces of a plurality of chips carried by the chip testing device, the central control device controls the chip testing device to perform a testing operation to the chips. After the chip testing device performs the testing operation to the chips, a plurality of movable members of the pressing device protrude from a contacting surface of the pressing device and push the chips to separate the chips and the contacting surface.
