Solution Overview

Problem

Conventional charging cradles for portable phones are specific to particular devices, making them uneconomical for replacement or use with different models, and expose connectors to the environment, leading to potential connection issues.

Innovation Solution

A universal dock that accommodates various phone sizes and types, allowing slanted cradling while enclosing the phone, protecting the connector, and featuring a retractable and rotatable connector design to ensure compatibility and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a dedicated charging cradle is designed for a particular phone model, then the connector connection is reliable, but the device complexity and production cost increase due to multiple models

Engineering Contradiction:
Improveconnector connection reliabilityVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The charging cradle is designed with a universal cradle space and retractable connector that can accommodate multiple phone models and connector types (USB, micro USB, etc.), allowing a single cradle design to serve multiple functions and reduce the need for model-specific cradles

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

2Ease of operation

If the connector is exposed to the external environment, then the connection is accessible, but the connector reliability deteriorates over time due to environmental exposure

Engineering Contradiction:
Improveconnector accessibilityVSAvoidconnector connection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connector is designed to be retractable rather than fixed, allowing it to move between an exposed position for connection and a retracted position for protection. This dynamic design enables the connector to be accessible when needed while protected when not in use, resolving the contradiction between accessibility and reliability

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If an exterior case is added to protect the portable phone, then the phone is protected from exterior damage, but the connector cannot be connected due to the case enclosure

Engineering Contradiction:
Improveprotection from exterior damageVSAvoidconnector connection ease
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The exterior case is designed with a separate connector access portion that allows the connector to be accessed independently from the main phone body. This segmentation enables the connector area to be accessible while the rest of the phone remains protected by the exterior case

Inventive Principle:
Principle #1Segmentation
