Solution Overview

Problem

Conventional mobile device keypads are cumbersome for non-calling functions, requiring users to memorize special sequences for tasks like playing songs or games, and lack intuitive interfaces for multiple applications.

Innovation Solution

A programmable keypad system that dynamically changes layouts based on user requests, applications, and inputs, using logic to provide tactile feedback and illumination, allowing inputs via touch, stylus, or voice, and supporting multiple languages and configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional keypad is used on mobile devices, then the device can perform calling functions, but the keypad becomes cumbersome for non-calling functions requiring memorization of special sequences

Engineering Contradiction:
Improvekeypad functionality for multiple applicationsVSAvoidusability for non-calling functions
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The keypad layout is made dynamic and reconfigurable through software, allowing it to change based on the current application or function being performed. The system includes a processor that receives user inputs and dynamically reconfigures the keypad layout to provide intuitive interfaces for different functions such as music control, gaming, or messaging, eliminating the need for users to memorize special sequences.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The keypad's functional parameters are changed through software control rather than hardware modification. The processor modifies the keypad's behavior and layout parameters based on the active application, transforming a static physical keypad into a flexible interface that adapts its functionality according to user needs and current device operations.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the keypad layout is fixed for calling functions, then the structure remains simple, but the device cannot provide intuitive interfaces for multiple applications

Engineering Contradiction:
Improvesupport for multiple applications and functionsVSAvoidkeypad configuration system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The keypad is designed with universal multi-functionality, serving as an adaptive interface for numerous applications including calling, messaging, music control, gaming, and more. Rather than requiring separate specialized inputs for each function, a single reconfigurable keypad handles all functions by changing its layout and behavior based on the active application.

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

Solution Approach 2:

The keypad system provides self-service functionality where the processor automatically detects the active application and configures the appropriate keypad layout without requiring manual user setup. The system serves itself by autonomously adapting the interface based on device state and current operations.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If users must memorize special sequences for non-calling functions, then the keypad structure remains simple, but the ease of use decreases significantly

Engineering Contradiction:
Improveintuitiveness of keypad usageVSAvoidtime required to learn and remember sequences
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The keypad layout dynamically adapts to the current application, automatically presenting intuitive controls for music playback, gaming, or other functions without requiring users to recall memorized sequences. The system transitions from a static layout requiring memorization to a dynamic interface that provides context-appropriate controls.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system provides feedback to users about the current keypad configuration and available functions based on the active application. This feedback mechanism helps users understand the current state and available options without requiring prior memorization, reducing cognitive load and improving ease of use.

Inventive Principle:
Principle #23Feedback
