Solution Overview

Problem

Current electronic devices require time-consuming disassembly and reassembly processes due to the need to remove and reattach multiple plastic cosmetic panels, which can be cumbersome and prone to errors or damage during servicing.

Innovation Solution

An electronic device design featuring a cosmetic envelope that can be easily assembled into a single piece before being fastened to the housing, utilizing clipping means and a single screw for secure attachment and detachment, allowing for simplified access to internal components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If multiple plastic cosmetic panels are used to cover the housing, then the cosmetic appearance is improved, but the disassembly and reassembly process becomes time-consuming and complex

Engineering Contradiction:
Improvecosmetic appearanceVSAvoiddisassembly and reassembly time
Core Design Contradiction:
ShapeVSLoss of time

Solution Approach 1:

The patent combines multiple separate plastic cosmetic panels into a single integrated cosmetic envelope that surrounds the housing. This envelope is formed as one piece and fastened to the housing through a single disassembly/reassembly process, thereby maintaining cosmetic appearance while significantly reducing servicing time and complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Shape

If multiple plastic panels are fixed independently to the housing, then the cosmetic coverage is improved, but the risk of damage during disassembly increases

Engineering Contradiction:
Improvecosmetic coverageVSAvoidrisk of damage during servicing
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

By merging multiple cosmetic panels into a single integrated envelope, the patent eliminates the need to handle and reattach multiple separate pieces during servicing. This reduces the risk of losing screws, breaking panels, or causing damage during the disassembly and reassembly process, while still providing complete cosmetic coverage.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the cosmetic envelope is made of a single piece, then the assembly process is simplified, but the manufacturing complexity increases

Engineering Contradiction:
Improveassembly processVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent divides the manufacturing process into two distinct stages: first, forming the cosmetic envelope as a single integrated piece (which may involve molding multiple panels together as one unit), and second, fastening this pre-formed envelope to the housing. This segmentation allows the manufacturing complexity to be managed separately from the assembly simplicity, enabling easy servicing while maintaining manufacturability.

Inventive Principle:
Principle #1Segmentation
