Solution Overview

Problem

Existing protective enclosures for electronic devices are often complex to assemble and require multiple pieces, making them difficult to install and remove, while also obscuring the device's style and functionality.

Innovation Solution

A one-piece multi-layered protective enclosure with a structural member overmolded with cushioning, providing shock absorption and protection while allowing for easy installation and removal, and featuring transparent components to showcase the device's design and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multi-piece protective enclosures are used to provide cushion and structural layers, then protection reliability is improved, but device complexity and ease of operation deteriorate due to complicated assembly instructions and multiple assembly steps

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

Solution Approach 1:

The patent combines multiple protective layers (structural layer and flexible cushion layer) into a single integrated one-piece enclosure that fits over the electronic device. This merging eliminates the need for separate assembly steps while maintaining the protective benefits of multiple layers, directly resolving the contradiction between protection reliability and assembly complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The one-piece enclosure is designed with a specific geometric structure that segments the protective function into different zones: a rigid structural layer for impact resistance and a flexible cushion layer for shock absorption. This internal segmentation allows multiple protective functions to be achieved within a single piece, avoiding the need for multiple separate components

Inventive Principle:
Principle #1Segmentation

2Reliability

If multi-layer protective enclosure is used to provide comprehensive protection, then protection reliability is improved, but ease of operation deteriorates due to difficulty in installation and removal

Engineering Contradiction:
Improveprotection reliabilityVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By merging the structural layer and cushion layer into a single pre-assembled unit, the enclosure can be installed and removed as one piece. This eliminates the need for users to perform multiple assembly steps, significantly improving installation ease while maintaining comprehensive protection through the integrated multi-layer structure

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If opaque protective enclosure is used to provide complete coverage, then protection reliability is improved, but aesthetic appearance deteriorates by obscuring the device style

Engineering Contradiction:
Improveprotection reliabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The enclosure applies different optical properties to different regions: the back portion is made transparent to showcase the device's aesthetic appearance, while the side portions maintain protection. This local differentiation of material properties allows the enclosure to simultaneously achieve comprehensive protection and aesthetic appeal by matching the transparency level to the specific functional requirements of each region

Inventive Principle:
Principle #3Local quality

4Shape

If transparent components are added to showcase device design, then aesthetic appearance is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The transparent back portion and cushion layer are combined into a single integrated component through overmolding. This merging of transparent and protective functions into one manufacturing step avoids the need for separate assembly operations, thereby improving aesthetic appearance while minimizing the increase in manufacturing complexity

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A protective enclosure for an electronic device includes a cushioning member and a structural member. The cushioning member covers the side surfaces of the installed electronic device and includes a first raised edge and second raised edge, the first raised edge extends around the front edge of the installed electronic device and the second raised edge extends around the back edge of the installed electronic device. The cushioning member is not configured to cover the back surface of the installed electronic device. The structural member is affixed to the cushioning member and includes a back portion and side portions, the back portion extends around the second raised edge of the cushioning member and covers the back surface of the installed electronic device, the second raised edge of the cushioning member forming a gap between the inner surface of the structural member and the back surface of the installed electronic device.
