Compressible Cushioning Latch for Speaker Base Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing speakers to projector bases using screws and silica gel or rubber are time-consuming, labor-intensive, and require specialized screws, increasing costs and complexity.
Innovation Solution
A cushioning member made of a compressible material with a support portion and latch portions that can be buckled between the speaker and the base to provide both cushioning and locking functions without additional locking elements or actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to lock the speaker to the base, then the connection strength is improved, but the assembly time and labor intensity increase
Solution Approach 1:
The cushioning member integrates both cushioning material and locking structure into a single component. The latch portion forms an integrated locking mechanism that engages with the base, while the cushioning material provides vibration absorption. This merging eliminates the need for separate screws and cushioning elements, reducing assembly steps and time while maintaining connection strength.
Solution Approach 2:
The latch portion is designed to automatically engage with the base when the cushioning member is compressed during assembly. The elastic deformation of the latch allows it to snap into the locking groove without requiring additional locking actions or tools. This self-service mechanism eliminates the need for manual screw tightening and reduces labor intensity.
2Reliability
If specialized screws are used to match the silica gel or rubber, then the connection reliability is improved, but the device complexity and cost increase
Solution Approach 1:
The cushioning member serves multiple functions simultaneously: it provides vibration absorption through its cushioning material, structural support through its rigid portions, and automatic locking through the latch mechanism. This multi-functionality eliminates the need for specialized matching components and reduces overall device complexity while maintaining connection reliability.
Solution Approach 2:
The locking function is extracted from the traditional screw mechanism and integrated into the cushioning member itself through the latch portion. This extraction allows the use of common cushioning materials while incorporating a built-in locking mechanism, eliminating the need for specialized screws and reducing device complexity.
3Strength
If multiple screws are used for locking, then the connection strength is improved, but the number of parts and assembly complexity increase
Solution Approach 1:
Multiple locking functions are merged into a single cushioning member through the latch portion. The latch can engage with multiple locking grooves or provide multi-directional locking capability, replacing the need for multiple separate screws and reducing the number of parts while maintaining connection strength.

AI summary
A cushioning member includes a support portion, a first latch portion, a second latch portion, a first connection portion, a second connection portion, a first guide portion and a second guide portion. The first guide portion, the first latch portion, and the first connection portion are arranged opposite to the second connection portion, the second latch portion and the second guide portion on basis of the support portion as a center. When the first and second latch portions are in a relaxed state, a width of the support portion in a direction perpendicular to the axial direction is greater than a width of the first latch portion and a width of the second latch portion in the direction.
