Solution Overview
Problem
Existing test systems for electrical assemblies face challenges in safely arranging and exchanging electrical components without causing mechanical or electrical damage, as they are sensitive to such influences.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional test system uses a simple opening mechanism for replacing electrical assemblies, then the device complexity is reduced, but the mechanical stress on electrical assemblies increases and the reliability of safe arrangement deteriorates
Solution Approach 1:
The support element is designed to be pivotable relative to the first support element, transitioning between open and closed positions. This dynamic mechanism allows controlled movement that prevents improper mechanical stress while enabling safe arrangement and replacement of electrical assemblies, resolving the contradiction between reliability and device complexity
Solution Approach 2:
The test system is divided into separate support elements (first support element and pivotable support element) that can move independently. This segmentation allows the fixing module to be applied selectively when needed, improving safety without requiring the entire system to be complex, thus resolving the contradiction between reliability and device complexity
2Stability of the object's composition
If the support element moves directly in linear direction without pivoting motion, then the device complexity is reduced, but the mechanical stress on electrical assemblies increases and even force application cannot be achieved
Solution Approach 1:
The support element employs a two-phase movement mechanism: first pivoting relative to the first support element, then moving linearly in the direction of the first support element. This dynamic sequence ensures orthogonal fixation and even force application during the closing motion, resolving the contradiction between stability of force application and device complexity
Solution Approach 2:
The pivoting motion occurs at the beginning of the closing process, before the linear movement phase. This preliminary action positions the fixing module correctly to apply force orthogonally, ensuring even force distribution on the electrical assembly before the final linear pressing occurs, thus resolving the contradiction between stability and device complexity

AI summary
One aspect concerns a lockable base module (14) for a modular test system (10) for testing electrical assemblies, comprising: - a first support element (24) which provides a receiving space (26) for receiving a test module (16), wherein an electrical assembly to be tested can be arranged on the test module (16); - a second support element (28) pivotably mounted relative to the first support element (24), which is designed to receive a fixing module (22) for fixing the electrical assembly to be tested on the test module (16); - an operating unit (100) pivotably mounted on the first support element (24), which is guided on the second support element (28), wherein by pivoting the operating unit (100) relative to the first support element (24), the second support element (28) is moved into an open position,in which the electrical assembly to be tested is released by the fixing module (22), and is movable into a closed position in which the electrical assembly to be tested is fixed to the test module (16) by the fixing module (22), and wherein the second support member (28) follows a movement from the open position to the closed position by pivoting the operating unit (100) such that at the beginning of the movement of the second support member (28), the second support member (28) is pivoted relative to the first support member (24), and at the end of the movement, the second support member (28) is moved linearly in the direction of the first support member (24).
