Solution Overview

Problem

Conventional protective cases for foldable electronic devices are bulky and heavy, compromising their aesthetic appeal and functionality while failing to adequately protect the device's edges and fold axis, and there is a need for a solution that minimizes bulk and weight while maintaining impact protection and versatility.

Innovation Solution

A compact, two-piece protective covering with interconnected shielding bodies and a flexible hinge system, featuring a cover panel that can extend to cover the device's rear display and include a storage compartment, designed to be user-removable and adaptable to various devices, with resilient materials and cushioning for shock absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional protective cases are used to protect the device from impact, then impact protection is improved, but bulk and weight increase

Engineering Contradiction:
Improveimpact protectionVSAvoidcase weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The protective case is divided into two separate shielding bodies (first and second shielding bodies) that can be interconnected via a hinge. This segmentation allows each body to be optimized for protection while the overall structure remains lightweight and compact compared to a single bulky case.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The case employs thin shielding bodies with resilient materials that provide impact protection through flexibility rather than bulk. The resilient materials absorb shock while maintaining a slim profile, avoiding the need for thick, heavy protective layers.

Inventive Principle:
Principle #30Flexible shells and thin films

2Reliability

If conventional protective cases are used to protect the device from impact, then impact protection is improved, but aesthetic appearance deteriorates

Engineering Contradiction:
Improveimpact protectionVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The thin shielding bodies with resilient materials maintain a sleek, modern aesthetic while providing adequate impact protection. The flexible nature of the materials allows for a form-fitting design that enhances rather than detracts from the device's appearance.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The two-piece design with hinge connection allows for a more refined aesthetic compared to a single bulky case. Each shielding body can be contoured to match the device's shape, creating a more visually appealing protective covering.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If additional structures are added to increase case functionality, then versatility is improved, but bulk and weight increase

Engineering Contradiction:
Improvecase functionalityVSAvoidcase weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The hinge connection between the two shielding bodies enables multiple functions: protecting the fold axis, supporting the device in various orientations, and allowing the case to adapt to different device configurations. This multi-functionality is achieved through the hinge mechanism itself rather than adding separate heavy components.

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

Solution Approach 2:

The hinge provides dynamic adaptability, allowing the case to move and adjust to different device positions and orientations. This dynamic functionality replaces static, bulkier structures that would be needed to provide the same versatility.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If additional structures are added to increase case functionality, then versatility is improved, but the case becomes cumbersome

Engineering Contradiction:
Improvecase functionalityVSAvoidcase complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hinge serves multiple functions simultaneously: it protects the fold axis, enables various viewing orientations, and allows the case to conform to different device states. This universal mechanism avoids the need for multiple separate components, reducing overall complexity.

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

Solution Approach 2:

The hinge combines several functions into a single integrated component, merging the fold axis protection with the orientation support capabilities. This consolidation reduces the number of separate parts and simplifies the overall case structure.

Inventive Principle:
Principle #5Merging (Combining)

5Reliability

If a protective case covers the entire device including fold axis, then protection is improved, but bulk increases

Engineering Contradiction:
Improvefold axis protectionVSAvoidcase volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The case is segmented into two shielding bodies that connect via a hinge, allowing the case to wrap around and protect the fold axis without requiring a single large bulky structure. Each shielding body covers a specific portion of the device, and the hinge connects them at the fold axis.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hinge provides dynamic adaptation to the folded and unfolded states of the device, allowing the case to protect the fold axis only when needed (in folded state) while maintaining a compact profile in both states.

Inventive Principle:
Principle #15Dynamics
