Adjustable Fixing Jig for Gap-Free Vibration Test Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vibration testing of computer servers, gaps between the stopper and the workpiece reduce the accuracy of the tests due to inadequate fixation, leading to potential misalignment and instability.
Innovation Solution
A fixing jig comprising a support plate, a fixing member with a receiving groove, an adjusting member, and a locking member is used to securely position the workpiece, where the stopper is slidably received in the groove and adjusted by the adjusting member, and locked by the locking member, ensuring precise horizontal and vertical stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple stopper is used to fix the workpiece, then the device complexity is reduced, but the positioning precision and fixation reliability deteriorate due to gaps between the stopper and workpiece
Solution Approach 1:
The fixing device is divided into multiple functional segments: a stopper for initial positioning, an adjusting member with threaded structure for precision adjustment, and a locking member for securing. This segmentation allows each component to perform its specific function while achieving overall high positioning precision without excessive complexity.
Solution Approach 2:
The adjusting member introduces dynamic adjustability to the otherwise static stopper structure. By incorporating a threaded adjusting member that can be rotated to move the stopper precisely, the system transitions from a fixed simple structure to a dynamically adjustable one, resolving the contradiction between simplicity and precision.
2Ease of operation
If a simple stopper is used to fix the workpiece, then the ease of operation is improved, but the fixation reliability deteriorates due to gaps and instability
Solution Approach 1:
The fixing operation is segmented into three simple sequential steps: placing the workpiece against the stopper, rotating the adjusting member to eliminate gaps, and securing with the locking member. This segmentation makes the complex task of achieving reliable fixation simple and intuitive to operate.
Solution Approach 2:
The threaded adjusting member allows the operator to self-adjust the stopper position by simple rotation, automatically eliminating gaps between the stopper and workpiece. This self-adjusting mechanism improves fixation reliability while maintaining ease of operation, as the system performs the precision adjustment function through a simple user action.
3Device complexity
If the stopper position is fixed without adjustment capability, then the device complexity is reduced, but the adaptability deteriorates due to inability to eliminate gaps
Solution Approach 1:
The static stopper structure is transformed into a dynamic, adjustable one by incorporating the threaded adjusting member. This allows the stopper to adapt its position to different workpiece dimensions and requirements, eliminating gaps while adding minimal structural complexity through the straightforward threaded mechanism.
Solution Approach 2:
The adjusting member enables continuous change of the stopper's position parameter along the horizontal axis. By rotating the adjusting member, the stopper can be positioned at any required location to match different workpiece sizes, providing adaptability without requiring multiple different stopper components.

AI summary
A fixing jig includes a support plate for supporting a workpiece. A fixing member is arranged on the support plate and defines a receiving groove penetrating a bottom surface of the fixing member. A stopper is slidably received in the receiving groove. A bottom surface of the stopper is flush with the bottom surface of the fixing member and contacts the support plate. An end of the stopper extends out of the receiving groove and abuts against the workpiece. The adjusting member is coupled to the fixing member. One end of the adjusting member extends into the receiving groove and is coupled to the stopper. The adjusting member is used to adjust a position of the stopper. The locking member is arranged on the adjusting member and used to lock a position of the adjusting member, thereby locking the position of the stopper.
