Boom Stand Locking Mechanism for One-Knob 3-Axis Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stands, such as cymbal stands, require multiple screws to be loosened and tightened simultaneously for adjustments in multiple directions, making them inconvenient to use.
Innovation Solution
A stand adjustment device with a tripod-connecting member, connecting seat, distal clamping plate, boom-connecting tube, locking shaft, and manual operating member allows for simultaneous adjustment in three directions (rotation, vertical rotation, and sliding) using a single manual operating element, ensuring ease of use and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple adjustment screws are used for multi-directional adjustment, then adjustment precision is improved, but operation complexity increases and ease of operation deteriorates
Solution Approach 1:
Multiple adjustment screws are merged into a single integrated adjustment mechanism. The adjustment device includes a first adjustment screw for vertical rotation, a second adjustment screw for horizontal rotation, and a third adjustment screw for sliding, all integrated into one system that can be operated simultaneously or sequentially to achieve multi-directional positioning with improved ease of operation while maintaining adjustment precision.
2Measurement precision
If multiple adjustment screws are used for multi-directional adjustment, then adjustment precision is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism employs a nested structure where the first, second, and third adjustment screws are arranged in a nested configuration. The connecting seat rotates vertically on the tripod-connecting member via the first adjustment screw, while the boom-connecting tube rotates horizontally on the connecting seat via the second adjustment screw, and the boom slides along the boom-connecting tube via the third adjustment screw. This nested arrangement integrates multiple adjustment functions into a compact structure, reducing overall device complexity while maintaining precise multi-directional adjustment capability.
3Reliability
If conventional stands require loosening and tightening multiple screws, then secure locking is achieved, but time consumption increases
Solution Approach 1:
The adjustment device is pre-configured with multiple adjustment screws (first, second, and third) that are preliminarily positioned and ready for operation. The springs associated with each screw mechanism are pre-compressed or pre-tensioned to provide immediate locking force. When adjustment is needed, the user can quickly operate the integrated mechanism, and the springs automatically engage the locking positions, significantly reducing the time required compared to manually loosening and tightening multiple separate screws while maintaining secure locking reliability.

AI summary
A stand adjustment device has a tripod-connecting member, a connecting seat, a distal clamping plate, a boom-connecting tube, a locking shaft, and a manual operating member. The connecting seat is rotatably located around the tripod-connecting member. The distal clamping plate is detachably attached to a side of the connecting seat. One end of the locking shaft is movably disposed in the boom-connecting tube. The boom is slidably mounted through the boom-connecting tube and the locking shaft. The locking shaft is slidably mounted through the boom-connecting tube, the distal clamping plate, and the connecting seat such that the boom-connecting tube is rotatable relative to the connecting seat. The manual operating member and the locking shaft are configured to clamp the boom-connecting tube, the distal clamping plate, and the connecting seat therebetween into a locked condition.
