Solution Overview

Problem

Portable electronic devices face challenges in efficiently utilizing limited space for user input and output, as existing touch-sensitive technologies often require multiple buttons and menus, which can lead to inadvertent function activation and reduced usability.

Innovation Solution

The method involves detecting touches on multiple hardware components, including a touch-sensitive display and functional components like the microphone, speaker, and camera, to associate specific functions with gestures and taps, allowing for intuitive control without additional buttons or menus, using capacitive touch sensors and a processor to identify and perform functions based on touch attributes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple buttons and menus are added to provide more functions, then device functionality is improved, but device space is consumed and usability is reduced

Engineering Contradiction:
Improvedevice functionalityVSAvoiddevice space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

Existing hardware components (microphone, speaker, camera, buttons) are made multi-functional by detecting touches at their locations and associating different functions with different touch patterns. For example, the microphone can serve both its original audio function and act as a touch sensor for controlling other device functions, eliminating the need for separate buttons.

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

Solution Approach 2:

The patent combines the functions of touch sensing and hardware components by placing touch sensors at the locations of existing components like the microphone, speaker, and camera. This merging allows these components to serve dual purposes: their primary function and touch input function, thereby reducing the need for additional separate buttons and menus.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple buttons and menus are added to provide more functions, then device functionality is improved, but inadvertent function activation increases

Engineering Contradiction:
Improvedevice functionalityVSAvoidinadvertent activation
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent uses different touch patterns (tap, double-tap, long press) on the same hardware component to trigger different functions. This partial action differentiation allows the system to distinguish between intentional user actions and inadvertent touches, reducing false activations while providing multiple functions through the same physical location.

Inventive Principle:
Principle #16Partial or excessive action

3Area of stationary object

If touch-sensitive display is used for user input, then space is saved, but input precision and user control are reduced

Engineering Contradiction:
Improvedevice spaceVSAvoiduser control precision
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent places touch sensors at specific locations corresponding to hardware components (microphone, speaker, camera) rather than using a full touchscreen interface. This local quality approach provides precise touch input at key locations while saving overall device space, combining the benefits of both physical buttons and touch-sensitive display.

Inventive Principle:
Principle #3Local quality
