Innovation Solution

A mount assembly with spherical protrusions and non-identical recesses, combined with a magnetic fastener, allows for precise alignment and secure attachment through differential mechanical resistances and magnetic attraction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional alignment methods are used, then visual checks are required for accurate alignment, but the process becomes cumbersome and inefficient

Engineering Contradiction:
Improvealignment precisionVSAvoidmating operation ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces visual alignment methods with a magnetic field-based alignment system. Magnets embedded in the mounting plate create magnetic field lines that visually guide the positioning of the display module, eliminating the need for manual visual checks and complex alignment procedures while maintaining high positioning precision.

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

Solution Approach 2:

The patent introduces magnetic field lines as an intermediary between the mounting plate and display module. These field lines serve as both a visual guide for alignment and a mechanical force for secure attachment, bridging the gap between positioning accuracy and operational simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If secure attachment is achieved through mechanical means, then strong bonding is obtained, but demating becomes difficult

Engineering Contradiction:
Improveattachment strengthVSAvoiddemating ease
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The patent uses magnetic attraction as a dynamic attachment mechanism that can be easily activated and deactivated. The magnetic force provides strong holding strength during operation but can be easily overcome by applying gentle pulling force or tapping, allowing for simple demating and repositioning without permanent damage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the attachment parameter from permanent mechanical bonding to reversible magnetic attraction. This allows the attachment strength to be dynamically adjusted - strong enough to hold the display module securely during use, but easily reversible when demating is required for repair or repositioning.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If precise alignment is required, then visual checks and careful positioning are needed, but this reduces productivity

Engineering Contradiction:
Improvemating precisionVSAvoidassembly speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent enables self-alignment through the magnetic field lines that automatically guide the display module into the correct position on the mounting plate. The operator simply needs to bring the components close together, and the magnetic attraction automatically achieves precise alignment, eliminating time-consuming manual positioning while maintaining high manufacturing precision.

Inventive Principle:
Principle #25Self-service
