Solution Overview

Problem

Existing speaker enclosures with curved surfaces, such as capsule-shaped designs, face challenges in assembly and adaptation to different acoustic configurations due to complex protective part assembly and inability to easily personalize or adapt protective parts for various speaker layouts.

Innovation Solution

A protective piece for acoustic enclosures with curved surfaces, featuring a lateral and extreme protection portion, guided into position by a positioning device using magnets and centering pins, allowing easy assembly and disassembly, and adaptable to different acoustic configurations through adjustable holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If protective parts are designed for specific acoustic configurations with curved surfaces, then protection effectiveness and aesthetic appearance are improved, but assembly complexity and difficulty of adaptation to different configurations increase

Engineering Contradiction:
Improveprotection effectivenessVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protective piece is divided into two distinct portions: a lateral protection portion and an extreme protection portion. This segmentation allows each portion to be independently designed and assembled, simplifying the overall assembly process while maintaining comprehensive protection for different parts of the enclosure with curved surfaces

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protective piece is designed as a universal component that can be adapted to different acoustic configurations through the positioning device. The same protective piece structure can protect various speaker layouts by adjusting the positioning device, eliminating the need to redesign protective parts for each configuration

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

2Reliability

If protective parts are designed for specific acoustic configurations, then protection effectiveness is improved, but adaptability to different speaker layouts deteriorates

Engineering Contradiction:
Improveprotection effectivenessVSAvoidadaptability to different configurations
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The protective piece serves multiple functions: it protects both the lateral and extreme portions of the enclosure, and can be adapted to different acoustic configurations through the positioning device. This universal design allows the same protective piece to work with various speaker layouts without redesign

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

Solution Approach 2:

The positioning device enables dynamic adaptation of the protective piece to different acoustic configurations. The positioning device can be adjusted or repositioned to accommodate different speaker layouts, allowing the protective piece to maintain effectiveness across various configurations

Inventive Principle:
Principle #15Dynamics

3Shape

If protective parts use curved surfaces to match enclosure aesthetics, then aesthetic appearance is improved, but ease of assembly and disassembly deteriorates

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidease of assembly
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

By dividing the protective piece into lateral and extreme portions, each with its own concave surface matching the enclosure's curved geometry, the design maintains aesthetic appearance while enabling simpler assembly of manageable sections rather than one complex piece

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The positioning device acts as an intermediary mechanism that facilitates the assembly and disassembly of the protective piece with curved surfaces. It provides guidance and alignment, making it easier to install and remove the aesthetically shaped protective portions without compromising the curved surface match

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles
