Solution Overview

Problem

Modern communication devices, particularly those used in harsh environments like police or military applications, require ruggedized housings to withstand high accelerations, but existing solutions involve complex and labor-intensive support structures for separate speaker components.

Innovation Solution

A housing that integrally incorporates the speaker chassis and microphone, with a membrane support and magnet carrying support formed from a single material, allowing for simplified integration and secure fastening of the speaker components without additional mechanical effort, using features like recesses, drill holes, and clamps for enhanced stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate speaker is mounted in the housing using traditional support structures, then the speaker can be securely supported, but the housing requires extensive and complex support structures to withstand high accelerations

Engineering Contradiction:
Improvemechanical stabilityVSAvoidsupport structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the housing structure with the speaker chassis into a single integrated component. The housing itself forms the speaker chassis, eliminating the need for separate support structures. This is achieved by integrating the membrane support, magnet carrying support, and housing into one unified structure that directly supports the speaker components while withstanding high accelerations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing performs multiple functions simultaneously: it serves as the enclosure for the communication device, the chassis for the speaker, and the support structure for withstanding high accelerations. This multi-functionality eliminates the need for dedicated support structures, reducing overall device complexity while maintaining mechanical stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of manufacture

If traditional separate speaker mounting is used, then the speaker components can be independently assembled, but the mechanical effort and labor required for securing the speaker increases significantly

Engineering Contradiction:
Improveassembly effortVSAvoidmechanical stability under acceleration
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

By combining the housing and speaker chassis into a single integrated structure, the patent eliminates multiple assembly steps required for mounting separate speaker components. The integrated design allows speaker components to be directly installed into the housing structure without requiring separate support structure assembly, reducing labor while maintaining stability under high acceleration.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If separate speaker components are used with individual support structures, then each component can be optimized independently, but the overall device size and complexity increase

Engineering Contradiction:
Improvecomponent optimizationVSAvoiddevice compactness
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The integration of housing and speaker chassis into a single structure eliminates the need for separate support structures and mounting hardware, significantly reducing the overall device volume. The unified design allows speaker components to be directly positioned within the housing structure, improving compactness while maintaining the ability to optimize individual components through the integrated design process.

Inventive Principle:
Principle #5Merging (Combining)
