Solution Overview

Problem

Existing accessory devices for electronic devices require detachment of structural features for insertion or extraction, leading to potential damage and loss of components, especially when a power source is involved, as angular extraction can cause bending moments that may break connectors.

Innovation Solution

A unibody accessory device with a hidden hinge feature allows the first region to pivot and bend, enabling insertion or extraction without applying a bending moment to the connector, thus preventing damage and maintaining a single, integrated unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the accessory device uses a unitary structure with multiple structural features, then the protective coverage and aesthetic appearance are improved, but the risk of losing or misplacing structural features increases

Engineering Contradiction:
Improveprotective coverageVSAvoidloss of structural features
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent merges multiple structural features (protective cover, power supply, connector) into a single unitary accessory device. This integration ensures that all components remain together as one piece, eliminating the risk of losing individual structural features while maintaining comprehensive protective coverage.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If the electronic device is extracted at an angle from the accessory device, then the insertion and extraction process is simplified, but the connector may break off due to bending moment

Engineering Contradiction:
Improveinsertion and extractionVSAvoidconnector integrity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connector is designed with dynamic flexibility, allowing it to bend and pivot during insertion and extraction operations. This dynamic capability enables the connector to accommodate angular movements without breaking, while still maintaining a reliable electrical connection throughout the process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connector's physical parameters (flexibility, pivot angle) are optimized to allow angular extraction while preventing excessive bending moments. The connector can change its orientation and flexibility characteristics to accommodate the extraction motion without compromising structural integrity.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the accessory device includes a power supply and connector, then the functionality is enhanced, but the complexity of the device structure increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power supply, connector, and protective cover are merged into a single unitary structure. This integration reduces the number of separate components and assembly steps, thereby decreasing structural complexity while maintaining all desired functionalities including power supply and electrical connection capabilities.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An accessory device for an electronic device is disclosed. The accessory device may include a unitary body having a first region, a second region, and a hinge positioned between the first region and the second region. When a force is applied to the first region, the first region may bend or pivot at the hinge. When bent, the first region allows the electronic device to slide into or out of the accessory device. Further, the electronic device may slide into or out of the accessory device in a straight or linear manner. Also, the accessory device may further include a power supply designed to supply electrical current to a battery of the electronic device. The accessory device may further include a connector that electrically connects the power supply with the electronic device. The sliding motion of the electronic device prevents the connector from damage by bending.
