Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional memory chip testing apparatuses are inefficient due to high electricity consumption and long testing times, as they can only test one group of memory chips at a time with a predetermined test process, and cannot simultaneously test different groups with different processes.
Innovation Solution
An environment control apparatus and chip testing system that includes multiple accommodating chambers with adjustable temperature settings, allowing multiple chip testing devices to perform different testing processes simultaneously by connecting to an air suction device and external power supply, enabling independent temperature control and electricity provision to each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional memory chip testing apparatus tests only one group of memory chips at a time, then the testing process is simple and stable, but the testing time is excessively long and productivity is low
Solution Approach 1:
The testing system is divided into multiple independent accommodating chambers (first accommodating chamber, second accommodating chamber, etc.), each capable of testing a group of memory chips simultaneously. This segmentation allows parallel testing of multiple chip groups without increasing the complexity of individual testing units, thereby improving overall productivity while maintaining manageable device complexity.
Solution Approach 2:
Multiple accommodating chambers are merged into a single integrated testing system that shares common control and power supply infrastructure. The chambers work in parallel but are coordinated through a unified system, combining the benefits of simultaneous multi-group testing with the simplicity of standardized testing processes.
2Adaptability or versatility
If the conventional testing apparatus uses a predetermined testing process for all chips, then the process is stable and easy to control, but it cannot accommodate different testing requirements for different groups of chips
Solution Approach 1:
Each accommodating chamber is designed with universal functionality to perform the predetermined testing process, while the system as a whole can accommodate different testing requirements for different chip groups. The chambers can be independently configured to match specific testing needs without requiring complex customization of the underlying testing apparatus.
Solution Approach 2:
The system allows dynamic assignment of testing processes to different accommodating chambers based on the specific requirements of each chip group. While the core testing process remains predetermined and stable, the system can adaptively allocate and configure chambers to meet varying testing demands, providing flexibility without compromising process stability.
3Loss of time
If multiple groups of memory chips are tested sequentially in the conventional apparatus, then the testing process remains simple, but the testing time is excessively long
Solution Approach 1:
The multiple accommodating chambers enable continuous testing operations by eliminating idle time between testing batches. While one chamber completes its testing cycle, another chamber can simultaneously begin testing the next group of chips, ensuring continuous productive action and significantly reducing total testing time compared to sequential processing.
Solution Approach 2:
The system prepares multiple accommodating chambers in advance with all necessary testing configurations and power supply connections ready. This preliminary setup allows chip groups to be tested in parallel without interruption or reconfiguration delays, maximizing testing efficiency and minimizing total testing time.
4Productivity
If the conventional apparatus tests a large number of memory chips simultaneously, then productivity increases, but electricity consumption becomes excessively high
Solution Approach 1:
The power supply system is segmented into multiple independent power supply members, each dedicated to a specific accommodating chamber. This allows the system to activate only the power supply members needed for current testing operations, reducing overall power consumption compared to a single large-scale power system that would need to support all chambers simultaneously regardless of actual usage.
Solution Approach 2:
Each accommodating chamber has its own dedicated power supply member providing localized power, allowing the system to scale power consumption according to the number of active testing chambers. This local quality approach ensures that power is consumed only where and when needed, optimizing the balance between productivity and energy efficiency.

AI summary
An environment control device and a chip testing system are provided. An apparatus body of the environment control device includes a plurality of accommodating chambers. Each of the accommodating chambers has a temperature adjusting device disposed therein. Each of the accommodating adjusting devices includes a temperature adjuster, a contacting structure, a frame body, and an elastic annular enclosed member. When a chip testing device carrying a plurality of chips is disposed in one of the accommodating chambers, and the contacting structure contacts one side of the chips, the elastic annular enclosed member is abutted against the chip testing device, and the chip testing device and the contacting structure jointly define an enclosed space. The temperature adjuster can correspondingly adjust the temperature of the contacting structure so that the chip testing device can perform a predetermined testing process on the chips in a predetermined temperature environment.
