Offset Leg Musical Instrument Stand Reducing Setting Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing musical instrument stands, such as those described in U.S. Pat. No. 5,509,629, face a limitation in reducing the setting space due to the configuration of leg portions that cross the central axis of the pole, resulting in limited positioning flexibility.
Innovation Solution
A stand for a musical instrument featuring rotatable and offset legs that extend in a circumferential direction, allowing the longitudinal axis of the legs to be apart from the central axis without crossing it, enabling rotation and parallel alignment of legs to reduce the overall space requirement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If all leg portions are configured with axes crossing the central axis of the pole, then the structure is simple and easy to manufacture, but the setting space cannot be reduced effectively
Solution Approach 1:
The patent applies asymmetry by configuring at least one leg portion as an offset leg where the longitudinal axis is offset from the central axis of the pole without crossing it. This asymmetric arrangement allows the distal end portions of adjacent legs to be positioned closer together when rotated, thereby reducing the setting space of the stand while maintaining structural integrity and stability.
2Adaptability or versatility
If leg portions are rotated to be disposed adjacent to each other, then positioning flexibility is improved, but distal end portions remain positioned apart due to crossing axes configuration
Solution Approach 1:
The offset leg configuration with non-crossing axes enables legs to be rotated and disposed adjacent to each other with distal end portions positioned closer together, achieving both positioning flexibility and compact space utilization
Solution Approach 2:
The patent changes the spatial arrangement of leg axes from a crossing configuration to an offset configuration, utilizing dimensional optimization to reduce the circumferential space required while maintaining rotational capability and positioning flexibility

AI summary
Provided is a stand for a musical instrument, the stand including a pole in the shape of a stick extending in one direction, and a plurality of legs extending from the pole and arranged in a circumferential direction of the pole. At least one of the plurality of legs is a rotatable leg attached to the pole so as to be capable of rotating about a central axis of the pole. At least one of the plurality of legs is an offset leg held by the pole such that a longitudinal axis of the offset leg is apart from the central axis of the pole without crossing the central axis when viewed in an axial direction of the pole.
