Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If memory chips are inserted into electrical sockets by human or robotic arm, then the testing apparatus can operate, but the connection between chips and sockets becomes unstable
Solution Approach 1:
The patent replaces the mechanical insertion system (human hand or robotic arm) with a pneumatic pressing system. The air suction apparatus creates negative pressure that causes the abutting member to press the chip against the electrical socket, establishing reliable electrical connection without mechanical insertion operations.
Solution Approach 2:
The patent employs pneumatic principles by using an air suction apparatus to generate negative pressure within the accommodating space. This negative pressure causes the abutting member to move and press the chip firmly against the electrical socket, providing stable connection through pneumatic force rather than mechanical insertion.
2Ease of manufacture
If chips are not firmly connected to electrical sockets, then insertion process is simple, but testing results become incorrect
Solution Approach 1:
The patent performs preliminary action by establishing firm mechanical connection between the chip and electrical socket before the actual testing operation begins. The air suction apparatus creates negative pressure that pre-presses the chip against the socket, ensuring proper electrical contact is established before testing signals are applied.
Solution Approach 2:
The patent replaces the simple but unreliable mechanical insertion with a controlled pneumatic pressing mechanism. The air suction apparatus provides consistent and controllable pressing force to ensure the chip is firmly connected to the electrical socket, thereby guaranteeing accurate testing results.
3Reliability
If abutting member presses chips tightly, then connection stability improves, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary pneumatic system (air suction apparatus and accommodating space) between the control system and the chip-socket connection. This intermediary uses negative pressure to indirectly press the chip against the socket through the abutting member, achieving reliable connection without requiring complex direct mechanical pressing mechanisms.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus ensures stable and accurate connections between chips and sockets, preventing incorrect testing results by maintaining a firm connection during the testing process.
Implementation Method 1
The cover is configured to be connected to an air suction apparatus for expelling air in the accommodating space so as to cause the accommodating space to be under a negative pressure

AI summary
A testing apparatus includes a chip carrying device and a pressing device. The chip carrying device includes a circuit board and a plurality of electrically connecting units that are disposed on the circuit board and each can receive a chip. The pressing device includes a cover and an abutting member disposed between the cover and the electrically connecting units. The cover is disposed on the circuit board to jointly define an accommodating space that accommodates the abutting member and the electrically connecting units. The cover can be connected to an air suction apparatus for expelling air in the accommodating space. When the air suction apparatus performs a suction operation to expel the air in the accommodating space, the abutting member is abutted against the electrically connecting units and the chips so as to connect each of the electrically connecting units and the corresponding chip.
