Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an engaging component is used to connect the tablet computer with the base, then the connection can be made, but the detachment operation becomes complicated and inconvenient

Engineering Contradiction:

Improvedetachment operationVSAvoidengaging component mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the conventional mechanical engaging component with a magnetic connection system. Magnets are embedded in the base and corresponding magnetic components are provided on the tablet computer, enabling automatic magnetic attraction for connection and easy detachment by overcoming magnetic force, thereby simplifying the operation and reducing mechanical complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic connection system enables self-connection functionality where the tablet computer automatically attaches to the base through magnetic attraction when brought close together, eliminating the need for manual engagement operations and simplifying the user interface

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If a pivoting component is added to enable rotation of the tablet computer relative to the base, then rotation capability is achieved, but the structural space increases and component cost rises

Engineering Contradiction:

Improverotation capabilityVSAvoidpivoting component structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The magnetic connection system serves multiple functions simultaneously: it provides the connection mechanism, enables rotation through magnetic force variation, and maintains structural stability. This multi-functional approach eliminates the need for separate pivoting components while achieving rotation capability

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces mechanical pivoting components with a magnetic field-based rotation mechanism. By controlling the magnetic attraction force between the base and tablet computer, rotation is enabled without additional mechanical joints or moving parts, thereby reducing structural complexity and component count

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
