Boom Stand Locking Assembly for Single-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, proximal 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:
The patent combines multiple adjustment screws into a single integrated adjustment mechanism. The adjustable support leg incorporates a telescopic structure with locking grooves that can be adjusted in multiple directions (height, angle, lateral position) using one unified adjustment assembly rather than separate screws for each degree of freedom.
Solution Approach 2:
The single adjustment mechanism on the support leg serves multiple functions simultaneously - it controls height adjustment, angular positioning, and lateral positioning. This multi-functional design eliminates the need for multiple specialized screws while maintaining precise control over all adjustment parameters.
2Measurement precision
If multiple adjustment screws are distributed at different locations, then adjustment precision is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple distributed adjustment screws into a single integrated adjustment assembly on the support leg. The telescopic structure with locking grooves provides multiple adjustment capabilities (height, angle, lateral position) through one unified mechanism rather than separate distributed components.
Solution Approach 2:
The single adjustment mechanism performs multiple adjustment functions simultaneously - controlling telescopic extension for height, angular positioning for tilt, and lateral positioning for horizontal adjustment. This consolidates what would otherwise require multiple separate components into one multi-functional unit.
3Reliability
If multiple screws need to be loosened and tightened simultaneously, then secure locking is improved, but time consumption increases
Solution Approach 1:
The adjustment mechanism combines multiple locking functions into a single operation. The telescopic support leg uses one adjustment assembly with locking grooves that simultaneously secures height, angle, and lateral position when locked, eliminating the need to tighten multiple screws sequentially.
Solution Approach 2:
The locking grooves are pre-positioned at predetermined locations along the telescopic structure. When the adjustment mechanism is engaged, it automatically aligns with and locks into these pre-positioned grooves, providing secure multi-directional locking in a single action without requiring sequential tightening of multiple screws.

AI summary
A stand adjustment device has a tripod-connecting member, a connecting seat, a proximal 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 proximal 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 proximal 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 proximal clamping plate, and the connecting seat therebetween into a locked condition.
