Solution Overview

Problem

Conventional mobile devices face limitations in space for display and input units, leading to complex menu operations and inefficient use of additional functions due to the need for multiple input modes.

Innovation Solution

A method that utilizes a combination of a touch screen and a sensing module, including an illumination sensor and a camera module, to detect single or multi-inputs, allowing for the control of mobile device functions based on different input modes, enabling efficient use of various functions without complex menu operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional mobile devices use traditional display and input units, then mobility and portability are maintained, but space for additional functions is limited and menu operations become complex

Engineering Contradiction:
ImprovefunctionalityVSAvoidmenu complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a touch-sensitive display screen that serves multiple functions: it acts as both the display unit and the input unit, eliminating the need for separate physical keyboards. The gesture area extends the touch-sensitive functionality beyond the display edges, enabling additional control functions without adding physical components. This multi-functional approach allows the device to provide diverse services (communication, entertainment, information access) while maintaining a simple interface structure.

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

Solution Approach 2:

The patent introduces a gesture area that extends beyond the traditional display boundaries into the surrounding space. This spatial extension creates additional input zones in the dimensional space around the device, allowing users to access functions through gestures in the air space rather than navigating complex on-screen menus. The gesture area effectively adds a new dimension of interaction beyond the flat display surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If conventional mobile devices provide multiple input modes, then additional functions can be accessed, but operation efficiency decreases due to complex menu navigation

Engineering Contradiction:
Improvefunction accessVSAvoidoperation efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent extracts the input functionality from traditional physical keyboards and menus, relocating it to the gesture area surrounding the display. By taking out the complex menu navigation system and replacing it with direct gesture-based control in the extended touch area, the patent enables efficient access to multiple functions without requiring users to navigate through layered menus. The gesture area acts as a direct control interface that bypasses intermediate menu steps.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the touch-sensitive area is extended beyond display edges, then input flexibility is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveinput flexibilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent uses the same touch-sensitive technology for both the display area and the extended gesture area, maintaining manufacturing consistency. The gesture area utilizes the same capacitive or resistive touch sensing principles as the display, allowing a single manufacturing process to produce both regions. This approach provides enhanced input flexibility through the extended gesture zone while avoiding the need for separate manufacturing lines or additional component types.

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