Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In electronic devices with both sound output and wireless transmission functions, separate installation of antennas and speakers leads to space constraints, complicates assembly, and can cause resonance noise, limiting design flexibility and increasing assembly time.

Innovation Solution

Integrating the antenna with the speaker casing using a process like Laser Direct Structuring, allowing the antenna to be formed along the casing's contour, which reduces space occupancy, simplifies assembly, and prevents resonance by directly forming the antenna on the casing or attachment part.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an antenna and speaker device are separately installed in an electronic apparatus, then both functions can be independently implemented, but the electronic apparatus occupies more inner space and has reduced design flexibility

Engineering Contradiction:

Improvedesign flexibilityVSAvoidinner space occupancy

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent merges the antenna and speaker device into a single integrated structure where the antenna is formed on the speaker casing. This combination allows both wireless transmission and sound output functions to coexist in the same spatial footprint, reducing overall space occupancy while maintaining design flexibility for electronic apparatus integration

Inventive Principle:

Principle #5Merging (Combining)

2Ease of manufacture

If structure connection method is used to support antenna on speaker device, then both components can be assembled, but the connection design becomes too complicated causing strenuous and time-consuming assembly process

Engineering Contradiction:

Improveassembly processVSAvoidconnection design

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The antenna is directly formed on the speaker casing as an integrated structure, eliminating the need for separate connection components such as clips, adhesives, or mechanical fasteners. This integration dramatically simplifies the assembly process while reducing structural complexity compared to traditional separate installation methods

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces mechanical connection methods with a direct formation process where the antenna is created as part of the speaker casing structure itself. This substitution eliminates complex mechanical assembly steps and reduces manufacturing complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If there is an assembly gap formed between antenna and speaker device, then both components can be separately installed, but the speaker device resonates the antenna to generate annoying noise while outputting sound

Engineering Contradiction:

Improveresonance noiseVSAvoidassembly gap

Core Design Contradiction:

Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

By forming the antenna directly on the speaker casing as an integrated structure, the patent eliminates assembly gaps between separate components. This integration prevents the resonance phenomenon that occurs when gaps exist between the speaker device and antenna, thereby eliminating annoying noise while maintaining compact dimensions

Inventive Principle:

Principle #5Merging (Combining)
