Microphone Protective Cover With Transverse Pivot And Perpendicular Disengagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery-powered microphones are prone to accidental opening of the protective cover, leading to easy disconnection and battery fall-off due to the engaging mechanism's design, which requires perpendicular movement to disengage and pivot, causing unintentional opening and electrical disconnection.
Innovation Solution
A microphone design featuring a protective cover with a pivotable configuration about a transverse axis, including a cover body with pivot segments and pressing members that engage and disengage from the battery holder in different directions, and a resilient portion to secure the battery, allowing for safe closure and opening without accidental disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the protective cover is designed with an engaging block that openably engages the battery holder, then the cover can be opened to remove the battery, but the cover may be easily unintentionally opened causing the battery to fall off
Solution Approach 1:
The engagement mechanism is divided into two independent components: an engaging block on the cover body and a corresponding engaging structure on the battery holder. These segments work together through perpendicular disengagement motion followed by pivotal opening motion, providing both ease of operation and prevention of accidental opening.
Solution Approach 2:
The engagement block is designed to move in a direction perpendicular to the top-bottom direction for disengagement, and the cover body pivots about a transverse pivot axis. This multi-dimensional movement sequence (perpendicular translation + pivotal rotation) ensures that accidental touches cannot easily open the cover, while intentional operation remains simple.
2Ease of operation
If the cover body is drawn in transverse direction to disengage the engaging block, then the cover can be opened, but the battery may fall off easily causing electrical disconnection
Solution Approach 1:
The resilient portion is pre-configured to press against the battery and hold it in position within the battery holder. This preliminary securing action ensures that when the cover is opened by drawing the engaging block perpendicular to the top-bottom direction, the battery remains securely retained and cannot fall off causing electrical disconnection.
3Ease of operation
If the protective cover is pivotally connected to the battery holder, then the cover can open and close, but the connection mechanism adds complexity to the device
Solution Approach 1:
The engagement block and engaging structure are integrated directly into the cover body and battery holder respectively, eliminating the need for separate connection mechanisms. The resilient portion is also integrated into the cover body, combining multiple functions (engagement, pivoting, and battery retention) into a unified structure that reduces overall device complexity.
Solution Approach 2:
The cover body serves multiple functions: it protects the battery holder, provides a pivotal opening/closing mechanism, incorporates the engaging block for secure attachment, and includes the resilient portion for battery retention. This multi-functionality reduces the need for additional components, simplifying the overall device structure.

AI summary
A microphone includes a main body surrounding a longitudinal axis that extends in a top-bottom direction, a battery holder mounted to the main body, and a protective cover. The protective cover has a cover body pivotally connected to and openably covering the battery holder for retaining a battery therein, and a positioning unit connected to the cover body. The protective cover is pivotable about a pivot axis transverse to the top-bottom direction to turn upward and downward and to move between a closed position, where the positioning unit engages the battery holder, and an opened position, where the positioning unit is disengaged from the battery holder in a direction transverse to the top-bottom direction.
