Reconfigurable Test Rack MIC Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional test system racks and cabinets with static mass interconnects (MICs) lack adjustability, making it difficult for operators of varying sizes to interact with the system and limiting the system's flexibility for interfacing with other equipment.
Innovation Solution
The implementation of test system racks and cabinets equipped with actuators that allow the MIC to be adjusted in position without moving the legs or housing, and the integration of sensors to automatically detect and adjust the MIC position for optimal connection with other MICs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a static MIC is used in a test system rack, then the system structure is simple and stable, but the operator interaction becomes burdensome and the system flexibility is reduced
Solution Approach 1:
The patent applies the dynamics principle by transforming the static MIC positioning system into a dynamic one. The MIC is mounted on a movable platform that can be repositioned along the rack height using actuators (motorized or manual). This allows the MIC to adapt to different operator heights and preferences, significantly improving ease of operation while maintaining reasonable system complexity through modular design
Solution Approach 2:
The patent implements universality by designing a reconfigurable MIC positioning system that serves multiple functions: it can be adjusted for different operator sizes, accommodate various test equipment configurations, and interface with different second MIC positions on separate racks. This multi-functional capability increases system flexibility without proportionally increasing complexity
2Adaptability or versatility
If a static MIC is used, then the device structure is simple, but the system flexibility for interfacing with other equipment is limited
Solution Approach 1:
The dynamic positioning capability allows the MIC to be reconfigured for different interfacing scenarios. The actuator system enables the MIC to reach different heights and positions, allowing the same test system rack to interface with various equipment configurations, thereby achieving adaptability without requiring multiple dedicated systems
Solution Approach 2:
The patent changes the position parameter of the MIC dynamically. By adjusting the vertical position of the MIC along the rack using actuators, the system can adapt to different interfacing requirements with other equipment. This parameter change approach provides flexibility while maintaining a relatively simple adjustment mechanism
3Ease of operation
If the MIC position is fixed, then the installation is simple, but it is difficult for operators of varying sizes to interact with the system
Solution Approach 1:
The reconfigurable positioning system allows the MIC to be adjusted to different heights suitable for operators of varying sizes. This dynamic adjustment capability improves operator accessibility significantly, while the modular actuator design keeps the manufacturing process manageable through standardized components

AI summary
A test system rack or cabinet includes a housing containing instruments or equipment and a mass interconnect (MIC) mounted within the housing. The MIC has inputs to couple to the instruments or equipment and outputs to couple to a second MIC separate from the rack. The test system rack has legs positioned underneath the housing to support the housing and the first MIC. The test system rack has actuators configured to adjust a position of the first MIC without adjusting a position of the one or more legs.
