A magnetic field-generating arrangement using magnets to securely connect the body and module, allowing for adjustable positioning and simplified geometry, reducing the need for multiple fastening mechanisms and enhancing maintenance convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional fastening systems are used to connect the module to the body, then the connection is secure, but the device complexity increases and maintenance becomes more difficult

Engineering Contradiction:
Improveconnection stabilityVSAvoidfastening system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical fastening systems (screws, clips, latches) with a magnetic field-based connection system. Magnets embedded in the body and module create magnetic attraction forces that securely hold the module in place while eliminating complex mechanical fastening mechanisms, thus reducing device complexity while maintaining connection stability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the fastening function from complex mechanical systems and isolates it into a simplified magnetic field-based mechanism. By taking out only the essential connection function and implementing it through magnetic fields rather than mechanical means, the system achieves secure connection with minimal complexity

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If multiple fastening mechanisms are used to secure the module, then the connection stability improves, but the aesthetic appearance deteriorates due to visible fasteners

Engineering Contradiction:
Improvemodule connection stabilityVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

By replacing visible mechanical fasteners with hidden magnetic fields, the patent achieves secure module connection without any visible fastening elements on the exterior surfaces. The magnets are embedded within the body and module structures, creating an aesthetically pleasing sleek appearance while maintaining connection stability through magnetic attraction

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If complex fastening systems are used, then the module is securely fixed, but the ease of repair and maintenance deteriorates

Engineering Contradiction:
Improveconnection securityVSAvoidmodule removal and installation
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The patent replaces complex mechanical fastening systems that require tools and multiple steps with a simple magnetic connection system. The module can be easily removed and reinstalled by simply pulling it away from and pushing it toward the body, leveraging magnetic attraction and repulsion, thus dramatically improving ease of repair and maintenance while maintaining secure connection during operation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Manufacturing precision

If the module positioning is fixed, then the manufacturing precision is easier to achieve, but the adaptability to different environments deteriorates

Engineering Contradiction:
Improvemodule positioning precisionVSAvoidmodule placement flexibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic module positioning system where the module can be placed at multiple different locations around the body. Magnetic field distribution and gradient design enable the module to be securely held at various positions while maintaining manufacturing precision through controlled magnetic attraction zones that guide proper module placement

Inventive Principle:
Principle #15Dynamics
