Microphone Support Shaft Adjustment With Grooved Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headset-type acoustic devices lack a simple mechanism for adjusting the position of the arm member supporting the microphone unit, which is fixed and not user-friendly.
Innovation Solution
A shaft position adjustment mechanism with a movable rod-shaped shaft, a holding member, and a locking mechanism that includes a slider member and an urging member, allowing for easy adjustment of the microphone support member's position using a finger hook section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the arm member position is made adjustable, then the adaptability to user needs is improved, but the device complexity increases
Solution Approach 1:
The arm member is designed to be movable along the shaft in the extending direction, transforming from a fixed structure to a dynamic adjustable structure. This allows the arm member position to be changed according to user needs while maintaining a relatively simple mechanism through controlled movement capability.
2Stability of the object's composition
If a locking mechanism is added to fix the shaft position, then the stability of the adjusted position is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism utilizes the elastic force of the urging member to automatically press the slider member against the shaft, creating a self-locking effect. This self-service approach maintains position stability without requiring additional complex locking components or manual intervention.
Solution Approach 2:
The slider member acts as an intermediary between the urging member and the shaft. It translates the elastic force from the urging member into a pressing force that secures the shaft at the adjusted position, simplifying the overall locking mechanism while ensuring stable position maintenance.
3Ease of operation
If the slider member is made movable toward and away from the shaft, then the ease of operation is improved, but the reliability of position fixing may worsen
Solution Approach 1:
The slider member can be moved periodically between the locked position (pressing against the shaft) and the unlocked position (moved away from the shaft). This periodic action allows easy adjustment when needed while maintaining reliable position fixing during normal use, as the user can simply move the slider member to adjust or lock the position as required.
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
Enables simple and stable adjustment of the microphone unit's position by preventing unintentional unlocking and maintaining friction, even after repeated use, through a compact and efficient locking mechanism.
Implementation Method 1
an urging member that presses the slider member toward the shaft
Implementation Method 2
a claw that fits into the grooves

AI summary
A shaft position adjustment mechanism includes: a microphone support member that supports a microphone unit, and also has a rod-shaped shaft having formed thereon a plurality of grooves; a holding member having formed therein a shaft holding section that holds the shaft in a state where the shaft is movable; and a locking mechanism that fixes a position of the shaft, in which the locking mechanism has: a slider member that is provided to be movable in directions to move toward and move away from the shaft, and has formed thereon a claw that fits into the grooves; and an urging member that presses the slider member toward the shaft, and the slider member has formed thereon a finger hook section to be operated by a user in order to move the slider member to a position where the claw comes off from the grooves.
