Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current percussion instrument stands are heavy and bulky due to their steel construction, making them inconvenient to transport and difficult to set up in small areas, while also requiring larger footprints for stability.
Innovation Solution
A percussion instrument stand with a lightweight material construction, such as aluminum, magnesium, or carbon fiber, incorporating a magnetic dampening system to absorb impact energy and reduce tilting, lifting, and walking, allowing for a more compact and versatile design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel construction is used to withstand impact energy, then stability and strength are improved, but weight and footprint increase
Solution Approach 1:
The patent replaces the traditional mechanical approach of using heavy steel construction with a magnetic field-based dampening system. Magnets embedded in the stand base generate magnetic fields that interact with conductive materials in the legs, creating electromagnetic damping forces that absorb impact energy without requiring increased mass or structural reinforcement.
Solution Approach 2:
The patent changes the physical state and properties of the stand components by using lightweight materials with specific electrical conductivity properties. The legs are made from conductive materials (metal or carbon fiber) that enable electromagnetic interaction, while the base incorporates magnets with specific field strengths. This allows the system to achieve impact resistance through electromagnetic parameter interactions rather than mechanical mass.
2Stability of the object's composition
If heavier stands with larger legs are provided to increase stability, then resistance to lifting and tipping is improved, but portability and ease of setup deteriorate
Solution Approach 1:
The patent substitutes the mechanical stability approach (increasing mass and footprint) with an electromagnetic active stabilization system. The magnetic dampening system generates forces that actively counteract lifting and tipping motions during playing, allowing lightweight stands to achieve stability comparable to or exceeding heavier traditional stands.
Solution Approach 2:
The patent introduces dynamic electromagnetic damping that actively responds to impact forces during playing. The magnetic fields continuously adjust to counteract applied forces, providing adaptive stability rather than passive mechanical resistance. This dynamic response allows the stand to maintain stability under varying playing conditions without requiring excessive weight or footprint.
3Strength
If steel construction is used to resist deformation, then structural integrity is improved, but weight and transport convenience worsen
Solution Approach 1:
The patent replaces passive mechanical strength through material selection (steel) with active electromagnetic force generation. The magnetic dampening system provides structural support and impact resistance through electromagnetic forces rather than relying solely on material strength, enabling the use of lightweight materials that would otherwise lack sufficient structural integrity.
Solution Approach 2:
The patent employs composite construction combining lightweight materials (aluminum, magnesium, or carbon fiber) with electromagnetic components (magnets and conductive elements). This composite approach integrates structural lightweighting with active electromagnetic dampening functionality, achieving both reduced weight and maintained structural integrity.

AI summary
A percussion instrument stand includes an instrument support structure that supports the percussion instrument; a main body that supports the instrument support structure on a support base resting on a surface. The instrument support stand also includes a dampening system that absorbs impact energy transferred to the stand by a user playing the instrument via displacement off of an equilibrium orientation. The dampening system also provides a restoring force that returns the dampening system to the equilibrium orientation.
