Solution Overview

Problem

The pivotal connection between touch display and host modules in notebooks can lead to shaking during touch operations, affecting user experience and potentially damaging the connection.

Innovation Solution

An electromagnetic fixing mechanism that uses a mounted component, rotating component, locating module, fixing module, and control unit to prevent the touch display module from pivoting relative to the host module by applying a magnetic attraction force when the touch display is activated, utilizing a combination of recesses, balls, resilient components, and a fixing pillar to secure the rotating component in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the touch display module is pivotally connected to the host module to enable rotation, then the adaptability is improved, but the stability deteriorates causing shaking during touch operations

Engineering Contradiction:

Improverotation capabilityVSAvoidshaking during touch operations

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent implements a dynamic fixing mechanism that automatically adjusts between fixed and movable states. The electromagnetic component generates magnetic attraction force to hold the rotating component at fixed positions during touch operations, while allowing rotation when needed. This dynamic adjustment resolves the contradiction by making the system both adaptable (rotatable) and stable (fixed during operation) at different times.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the magnetic attraction force parameter dynamically. When touch operations are detected, the electromagnetic component activates to provide strong magnetic attraction, fixing the rotating component. When rotation is needed, the magnetic force is reduced or eliminated. This parameter change allows the system to transition between stable and adaptable states.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the touch display module is pivotally connected to allow rotation, then the adaptability is improved, but the reliability deteriorates due to easy damage of pivotal connection

Engineering Contradiction:

Improverotation capabilityVSAvoiddamage risk of pivotal connection

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The electromagnetic fixing mechanism dynamically locks the rotating component during touch operations, reducing mechanical stress and wear on the pivotal connection. This dynamic locking protects the pivotal connection from damage while preserving rotation capability when needed, thus improving reliability without sacrificing adaptability.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If electromagnetic component is added to prevent pivoting, then the stability is improved, but the device complexity increases

Engineering Contradiction:

Improveprevention of pivoting during touch operationsVSAvoidnumber of components

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges the electromagnetic component with the existing mounting structure. The electromagnetic component is integrated into the mounted component, and the fixing module is combined with the locating module. This merging reduces overall device complexity while achieving the stability improvement.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The electromagnetic component serves multiple functions: it provides magnetic attraction to fix the rotating component, and it can be controlled based on touch operation detection. The fixing module also serves both as a locating mechanism and a fixing mechanism. This multi-functionality reduces the need for separate components, lowering device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
