Solution Overview

Problem

The challenge is to optimize the arrangement and structure of sensors in electronic devices with sliding roll structures, ensuring stable operation and optimal performance during sliding operations that extend or reduce the display area.

Innovation Solution

The electronic device incorporates a sensor-related structure that stabilizes sensor configuration and maintains optimal operating form, enabling stable image acquisition and processing through a sliding type mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a flexible display is mounted in a roll structure to enable sliding operation for size adjustment, then the display area can be extended or reduced, but a gap is formed that exposes the sensor module and compromises structural stability

Engineering Contradiction:
Improvedisplay area adjustmentVSAvoidsensor structure stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The sensor module is nested within a sensor module housing that is integrated into the roll structure. The housing contains the sensor module when the display is in rolled state, preventing exposure through the gap. This nesting approach allows the sensor to be protected while maintaining the sliding functionality for display area adjustment.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The device is segmented into distinct functional modules: the flexible display, the sensor module, and the sensor module housing. This segmentation allows independent optimization of each component - the display can slide for area adjustment while the sensor module remains stably housed in its dedicated compartment, resolving the contradiction between adaptability and stability.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the sensor module is exposed through the opening during sliding operation, then the sensor function may be accessed, but the sensor structure becomes unstable and image acquisition is compromised

Engineering Contradiction:
Improvesensor accessVSAvoidimage acquisition stability
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The sensor module is pre-positioned and secured within the sensor module housing before the sliding operation begins. This preliminary securing action ensures that regardless of the display's sliding state, the sensor maintains its precise position and stability, enabling reliable image acquisition without requiring exposure during operation.

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If the display is extended through sliding operation, then larger display area is achieved, but the sensor arrangement and structure require optimization to maintain stable operation

Engineering Contradiction:
Improvedisplay areaVSAvoidsensor arrangement complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The sensor module housing serves multiple functions: it protects the sensor module, provides structural support during sliding operations, and integrates seamlessly with the roll structure. This multi-functionality reduces the need for additional specialized components, simplifying the overall sensor arrangement while enabling large display area extension through sliding.

Inventive Principle:
Principle #6Universality (Multi-functionality)
