Solution Overview

Problem

Existing docking and charging solutions are often device-specific, fail to accommodate aftermarket cases, require users to manually connect charging plugs, and may damage components due to frequent plugging and unplugging, while also being costly with inferior quality transformers.

Innovation Solution

A docking system with adjustable holding elements and a motor-driven mechanism that accommodates various device sizes and cases, allowing for automatic alignment and charging, and optionally using wireless charging or data interfaces like Qi technology, with interchangeable plugs and clamping mechanisms for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If device-specific docking solutions are used, then charging reliability is improved, but adaptability deteriorates

Engineering Contradiction:

Improvecharging reliabilityVSAvoiddevice compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The docking system employs universal interfaces and adjustable holding elements that can accommodate multiple device types (smartphones, tablets, laptops) and various case thicknesses. The system provides device-agnostic charging capability while maintaining reliable electrical connection through standardized ports and adaptive clamping mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The docking system incorporates motor-driven adjustable holding elements that can dynamically adapt their position and clamping force to accommodate different device sizes and case thicknesses. This dynamic adjustment capability allows the system to maintain secure physical connection and proper alignment across various device configurations.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If manual plug connection is required, then device complexity is reduced, but ease of operation deteriorates

Engineering Contradiction:

Improvesystem simplicityVSAvoidcharging convenience

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The docking system features automatic plug connection functionality where the motor-driven mechanism autonomously inserts and secures the charging plug into the device port. This self-service capability eliminates the need for manual plug insertion while maintaining system simplicity, as the automated process occurs without user intervention after device placement.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary alignment and plug insertion actions automatically upon device docking. The motor-driven holding elements pre-position the charging plug and establish electrical connection before the user completes the docking process, improving convenience without adding significant complexity.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If frequent plugging and unplugging occurs, then adaptability is improved, but reliability deteriorates due to component damage

Engineering Contradiction:

Improvedevice interchangeabilityVSAvoidcomponent durability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The motor-driven adjustable holding elements provide dynamic, controlled connection and disconnection actions. Instead of frequent manual plugging and unplugging, the system uses automated motorized mechanisms to securely connect and disconnect devices, reducing mechanical stress on ports and connectors while maintaining high device interchangeability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The docking system incorporates cushioning and protection mechanisms that prevent damage during connection and disconnection. The motor-driven elements provide controlled, gentle insertion and removal forces, and the clamping mechanisms are designed to distribute stress evenly, protecting ports and connectors from damage even with frequent device changes.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

4Adaptability or versatility

If adjustable holding elements are added, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improvedevice size accommodationVSAvoiddocking system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustable holding elements serve multiple functions: they accommodate different device sizes, adjust to various case thicknesses, provide secure clamping force, and enable proper alignment for electrical connection. This multi-functionality achieves high adaptability without proportionally increasing system complexity, as a single mechanism handles multiple adjustment requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The docking system merges the adjustment mechanisms for different parameters (device size, case thickness, alignment) into an integrated motor-driven system. Rather than separate adjustment mechanisms for each parameter, the system combines these functions into coordinated motorized elements that simultaneously handle multiple adjustment tasks, reducing overall complexity.

Inventive Principle:

Principle #5Merging (Combining)
