Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If magnetic members are used to attach the electronic device to the docking device, then secure attachment is achieved, but the detachment force becomes fixed and cannot be adjusted for different applications

Engineering Contradiction:

Improveattachment securityVSAvoiddetachment force adjustment

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The magnetic member is made movable relative to the docking device, allowing the magnetic force to be dynamically adjusted between a first position (stronger attachment) and a second position (weaker attachment). This enables the system to adapt to different applications such as horizontal surfaces, vertical surfaces, and movable equipment by changing the magnetic force level based on mounting status and usage requirements.

Inventive Principle:

2Device complexity

If a fixed magnetic force is used for attachment, then the structure remains simple, but the system cannot accommodate various mounting scenarios requiring different detachment forces

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The magnetic member is made movable relative to the docking device, allowing the magnetic force to be dynamically adjusted between a first position (stronger attachment) and a second position (weaker attachment). This enables the system to adapt to different applications such as horizontal surfaces, vertical surfaces, and movable equipment by changing the magnetic force level based on mounting status and usage requirements.

Inventive Principle:

Solution Approach 2:

The magnetic force parameter is made adjustable by changing the position of the magnetic member. The system provides at least two discrete magnetic force levels (first and second positions), allowing users to select appropriate attachment strength for different scenarios such as secure mounting on movable equipment versus easier access on stationary surfaces.

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables secure attachment and easy detachment of electronic devices from docking devices, accommodating various use cases such as horizontal, vertical, and movable surfaces by adjusting magnetic forces.

Implementation Method 1
