Solution Overview

Problem

Existing accessories for electronic devices do not provide a stable pedestal or easy grip, limiting user convenience and functionality.

Innovation Solution

An accessory comprising a first and second housing connected by a hinge cover, with a connector that changes shape between unfolded and folded states, and includes a holder for user interaction, allowing easy grip and stable positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a connector is made rigid to maintain structural stability, then strength is improved, but adaptability to different device states (folded/unfolded) deteriorates

Engineering Contradiction:
Improveconnector strengthVSAvoidconnector adaptability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The connector is designed with a deformable portion that can dynamically change its shape between a first shape (when the electronic device is unfolded) and a second shape (when the electronic device is folded). This dynamic adaptability allows the rigid connector to maintain structural strength while adapting to different device configurations, resolving the contradiction between strength and adaptability.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If accessory structure is simplified for ease of manufacture, then ease of manufacture is improved, but functionality (stable pedestal and easy grip) deteriorates

Engineering Contradiction:
Improveaccessory manufacturing easeVSAvoidaccessory functionality
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The accessory is segmented into multiple functional components: a holder portion for providing easy grip, a connector portion for attaching to the electronic device, and a deformable portion that enables shape transformation. This segmentation allows each component to be manufactured independently with simple processes while collectively providing the full functionality of stable pedestal and easy grip features.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the holder is made larger for better grip, then ease of operation is improved, but device volume increases

Engineering Contradiction:
Improvegrip comfortVSAvoidaccessory volume
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The holder portion is designed as a thin, flexible structure that can be deformed to fit the user's hand grip. This flexible shell design provides comfortable grip and handling (improving ease of operation) while maintaining a compact form factor that does not significantly increase the overall volume of the accessory.

Inventive Principle:
Principle #30Flexible shells and thin films
