Pivoting Loudspeaker Mount With Locking Pitch Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loudspeaker assemblies lack the ability to securely position and adjust loudspeakers at various pitch angles relative to a mounting bracket, limiting flexibility and stability in installation.
Innovation Solution
A loudspeaker assembly with a mounting bracket and a locking mechanism that allows the loudspeaker to pivot between multiple pitch angles, utilizing a pivot pin and lock pin system with a switch mechanism to securely lock the loudspeaker in place, enabling easy adjustment and secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a loudspeaker is mounted to a flat surface without a locking mechanism, then installation is simple, but the loudspeaker cannot be securely positioned at various pitch angles
Solution Approach 1:
The mounting bracket incorporates a pivot pin that enables the loudspeaker to dynamically rotate between multiple pitch angles (e.g., 0°, 45°, 90°) relative to the mounting surface. This dynamic capability allows the loudspeaker to adapt to different installation requirements while maintaining a relatively simple bracket structure.
Solution Approach 2:
The locking mechanism is segmented into discrete lock features (notches or holes) positioned at specific pitch angles, with a lock pin that can engage with any of these features. This segmentation allows for selective locking at predetermined angles without requiring a continuous locking system, thereby maintaining structural simplicity while achieving versatile angle adjustment.
2Stability of the object's composition
If a locking mechanism is added to secure the loudspeaker at pitch angles, then positioning stability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-locking through a spring-loaded lock pin that automatically engages with the lock features at selected pitch angles. The spring provides continuous pressure to maintain engagement, and the mechanism self-maintains its locked state without requiring additional actuators or complex control systems, thereby achieving stable positioning with minimal added complexity.
3Adaptability or versatility
If the loudspeaker is made pivotable between multiple pitch angles, then installation flexibility is improved, but the reliability of secure positioning deteriorates
Solution Approach 1:
The lock features (notches or holes) are pre-positioned at specific pitch angles during manufacturing, and the lock pin is pre-configured to engage with these features. This preliminary arrangement ensures that when the loudspeaker is rotated to a desired angle, the locking mechanism is already prepared to securely lock it in place, maintaining both flexibility and reliability.
