Microphone Stand Expander Shaft for Stability and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio microphone stands become unstable with heavy microphones, are difficult to fold for portability, and occupy additional stage space when used with pedal boards.
Innovation Solution
A microphone stand design featuring a base section with a riser block and an expander shaft that allows the microphone holding section to rotate from horizontal to vertical orientations, incorporating a screw mechanism for engagement and an expandable shaft to maintain stability in the vertical position, and a handle for locking in the horizontal orientation for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional boom type microphone stand is used, then the microphone can be held at various positions, but the stand becomes unstable when a heavy microphone is used
Solution Approach 1:
The patent combines the microphone stand with a pedal board into a single integrated unit. The pedal board serves as the base, eliminating the need for a separate heavy base while providing stable support for the microphone boom arm. This merging of functions resolves the stability issue without requiring additional weight.
Solution Approach 2:
The spring mechanism is pre-loaded in the telescoping boom arm structure to provide continuous counterbalancing force. This preliminary action of pre-tensioning the spring ensures that the boom arm remains stable and controllable when supporting heavy microphones, preventing instability before it occurs.
2Ease of operation
If a conventional boom type microphone stand is used, then the microphone can be positioned flexibly, but the stand does not easily fold up for portability
Solution Approach 1:
The boom arm is divided into multiple telescoping segments that can slide in and out of each other. These segmented sections can be easily collapsed into a compact configuration for portability, while still providing flexible positioning when extended. The segmentation allows easy folding without compromising the ability to achieve various microphone positions.
3Area of stationary object
If a separate microphone stand is used, then the microphone can be held independently, but additional stage space is occupied when used with a pedal board
Solution Approach 1:
The microphone stand structure is merged with the pedal board, using the pedal board as the base platform. This integration eliminates the need for separate stand components, reducing the overall footprint on stage while maintaining the ability to independently position the microphone. The combined unit provides both pedal control and microphone support within a single space-efficient structure.
4Length of moving object
If a telescoping boom arm is used, then the microphone can be positioned at various distances, but the arm sags under heavy microphone weight
Solution Approach 1:
The spring mechanism is pre-loaded within the telescoping boom arm to provide continuous counterbalancing force against the weight of the microphone. This preliminary action of pre-tensioning the spring prevents sagging before it occurs, allowing the boom arm to extend to various lengths while maintaining stable support for heavy microphones throughout the range of motion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances stability with heavy microphones, facilitates easy folding and storage, and integrates seamlessly with pedal boards, optimizing stage space for musicians.
Implementation Method 1
The expander shaft expands from a compressed shaft position to an expanded shaft position when the microphone holding section rotates from the horizontal orientation to the vertical orientation to assist in holding the microphone holding section in the vertical orientation
Implementation Method 2
The riser block engages with the tube of the microphone holding section using a screw extending through apertures in the tube and the riser block

AI summary
A device for holding an audio microphone is disclosed. The microphone holding device includes a base section having a base plate connected to a riser block that engages with a tube of a microphone holding section to enable rotation of the microphone holding section from a horizontal orientation to a vertical orientation. The device also includes an expander shaft section including an expander shaft coupled at one end with the tube and at another end with base plate. The expander shaft expands from a compressed shaft to an expanded shaft when the microphone holding section rotates from the horizontal orientation to the vertical orientation to assist in holding the microphone holding section in the vertical orientation.
