Single-Knob Boom Stand Adjustment for 3-Axis Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stands, such as cymbal stands, require adjusting multiple screws simultaneously to adjust the position of an object, making the process inconvenient and cumbersome.
Innovation Solution
A stand adjustment device that allows for simultaneous adjustment in multiple directions using a single manual operating element, featuring a tripod-connecting member, connecting seat, clamping plates, a locking shaft, and a manual operating member, enabling easy positioning adjustments by clamping the boom, connecting seat, and distal clamping plate.
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
Solution Approach 1:
The patent combines multiple adjustment screws into a single integrated locking shaft that can simultaneously adjust height, rotation angle, and boom angle. The locking shaft integrates the functions of multiple separate adjustment mechanisms, allowing one-component operation while maintaining multi-directional adjustment precision through its interaction with multiple clamping plates and positioning portions.
Solution Approach 2:
The locking shaft serves multiple functions simultaneously: it acts as an adjustment mechanism for height, a locking mechanism for the connecting seat rotation, and an adjustment mechanism for the boom angle. This multi-functional design eliminates the need for separate screws for each adjustment direction, reducing operation complexity while preserving adjustment precision.
2Adaptability or versatility
If multiple adjustment screws are used, then adjustment capability is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple adjustment screws into a single locking shaft that integrates height adjustment, connecting seat rotation locking, and boom angle adjustment functions. This consolidation reduces the number of components while maintaining comprehensive adjustment capability across multiple directions.
Solution Approach 2:
The locking shaft is divided into multiple functional segments: a first clamping portion for height adjustment, a second clamping portion for boom angle adjustment, and positioning portions for rotational locking. This segmentation allows each function to be independently designed and optimized while being integrated into a single component, reducing overall device complexity.
3Measurement precision
If multiple screws need to be loosened and tightened, then positioning accuracy is improved, but time consumption increases
Solution Approach 1:
The locking shaft combines multiple adjustment operations into a single action. By rotating one component, the user simultaneously adjusts height, locks rotational position, and sets boom angle, eliminating the time-consuming process of loosening and tightening multiple separate screws while maintaining positioning accuracy through precise clamping and positioning mechanisms.
Solution Approach 2:
The clamping plates and positioning portions are pre-configured to engage with the locking shaft at specific positions. This preliminary arrangement allows the single locking shaft operation to immediately establish accurate positioning in multiple directions simultaneously, without requiring sequential adjustment and locking of multiple separate components.

AI summary
A stand adjustment device has a tripod-connecting member, a connecting seat, two clamping plates, a boom-connecting tube, a locking shaft, and a manual operating member. The connecting seat is rotatably located around the tripod-connecting member. The two clamping plates are detachably attached to two opposite sides of the connecting seat respectively. 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 two clamping plates, 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 two clamping plates, and the connecting seat therebetween into a locked condition.
