Problem

Modular electric systems face challenges with scalability, as existing mechanical connectors wear out and are visually unappealing, increasing the risk of wrong connections and damage due to short circuits, while also being costly.

Innovation Solution

The use of magnet elements on the base and load modules for holding and positioning, ensuring correct alignment and preventing incorrect connections, with magnet elements embedded in the substrate to maintain aesthetics and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If mechanical connectors (screws, tags, snap-on connections) are used for positioning load modules, then correct positioning is achieved, but the connectors wear out with time and have limited lifetime

Engineering Contradiction:
Improvepositioning accuracyVSAvoidconnector lifetime
Core Design Contradiction:
Manufacturing precisionVSDuration of action of stationary object

Solution Approach 1:

The patent replaces mechanical connectors (screws, tags, snap-on connections) with a magnetic field-based positioning system. Magnets embedded in the base module and corresponding magnetic elements on load modules create magnetic attraction forces that hold modules in correct positions without physical contact, eliminating wear and extending lifetime while maintaining positioning accuracy.

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

2Reliability

If standard electrical connectors are used for power supply and data transmission, then electrical connections are established, but the connectors are bulky and visible, decreasing the beauty of the system

Engineering Contradiction:
Improveelectrical connectionVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent replaces bulky mechanical electrical connectors with contactless power and data transmission technologies. This includes inductive coupling, magnetic coupling, or wireless communication methods that eliminate visible connectors, maintaining electrical connectivity while achieving a clean, aesthetic appearance.

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

Solution Approach 2:

The patent integrates electrical connection functionality within the magnetic positioning system. The same magnetic field interaction that provides mechanical positioning also enables contactless power and data transmission, nesting multiple functions within a single integrated system rather than using separate connectors.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple electrical contacts are added between parts for scalability, then power supply and data transmission capabilities are enhanced, but the risk of wrong connections and short circuits increases

Engineering Contradiction:
Improvesystem scalabilityVSAvoidconnection safety
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent incorporates feedback mechanisms that detect the position and orientation of load modules relative to the base module. The system provides tactile or visual feedback to guide correct placement, and only establishes electrical connections when proper alignment is detected, preventing wrong connections even as the number of contacts increases for enhanced scalability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces mechanical connector alignment systems with magnetic field-based positioning and contactless electrical transmission. The magnetic fields provide inherent guidance for correct positioning, and the contactless nature of power/data transmission eliminates the risk of short circuits between multiple contacts, enabling safe scalability.

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

4Reliability

If safety circuits are added to prevent damage from wrong connections, then protection against short circuits is improved, but the costs increase

Engineering Contradiction:
Improveprotection against short circuitsVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces complex safety circuitry with a magnetic field-based positioning and connection system. The magnetic fields inherently guide correct module placement and enable contactless power transmission, eliminating the need for additional safety circuits to prevent short circuits, thereby reducing manufacturing costs while maintaining or improving reliability.

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