Instrument Stand with Variable Pod Positions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional instrument stands with fixed relative angles between supporting pods face limitations in space usage and stability, making it difficult to adjust positions for multiple pedals and risking damage during assembly.
Innovation Solution
An instrument stand design featuring adjustable supporting pods with combining elements and a sliding positioning ring system, allowing for flexible ground contact positions and simplified assembly by fixing each pod before installation on the base, preventing damage during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed relative angles between supporting pods are used, then the structure is simple, but space usage is limited and cannot accommodate multiple pedals
Solution Approach 1:
The supporting pods are made adjustable through a mechanism involving positioning rings, combining elements, and angle adjustment features. This allows the relative angles between supporting pods to be dynamically changed, enabling flexible space usage to accommodate different numbers and positions of pedals while maintaining structural integrity
Solution Approach 2:
The supporting pod structure is divided into separate components including the supporting base, combining element, positioning ring, and angle adjustment mechanism. This segmentation allows each component to be independently adjusted and positioned, providing versatility in space configuration without requiring complete structural redesign
2Adaptability or versatility
If only two supporting pods are used to accommodate two pedals, then more space is allowed for pedals, but the installation procedure becomes complicated and stability worsens
Solution Approach 1:
The supporting pod design with adjustable angles and positioning rings serves multiple functions: it can accommodate different numbers of pedals (two or more), maintain structural stability through the three-pod configuration, and provide simplified installation through the pre-assembled combining element mechanism. The same structure adapts to various pedal configurations without compromising stability
Solution Approach 2:
The combining element is pre-assembled with the supporting pod and angle adjustment mechanism before installation on the stand. This preliminary assembly ensures proper positioning and stability is built into the structure, while also simplifying the final installation process as the entire assembly can be mounted as one unit
3Ease of manufacture
If supporting pods are installed directly on the positioning ring, then assembly is straightforward, but the installed supporting pod is likely to be damaged
Solution Approach 1:
The combining element serves as an intermediary component between the supporting pod and the positioning ring. It provides a protected interface for connection, allowing the supporting pod to be securely attached to the positioning ring through the combining element's connecting parts, thereby preventing direct contact that could cause damage while maintaining assembly simplicity

AI summary
An instrument stand with variable ground contact positions of its supporting pods is disclosed. It has a standing post mounted with two positioning rings. One of them is fixed, and the other can slide relative to the former. The positioning rings have several supporting bases and several connecting elements that fix with the supporting bases after angle adjustment. The supporting pods are locked on the two positioning rings. Each supporting pod is controlled by the relative motion of the two positioning rings to expand and collapse. The ground contact positions of the supporting pods of the invention are thus variable.
