Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a keyboard or mouse is used for computer input, then data entry function is achieved, but accessibility for diverse learners is worsened

Engineering Contradiction:

Improveaccessibility for diverse learnersVSAvoidcatering to different learning styles

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The input device is segmented into multiple independent tactile buttons arranged in a grid pattern, where each button can be independently actuated. This segmentation allows users to interact with the device through various tactile patterns and pressures, accommodating different learning styles and physical capabilities without requiring traditional keyboard or mouse operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a tactile feedback mechanism as an intermediary between the user and the computer system. This intermediary provides physical feedback to users during interaction, making the input process more accessible to individuals who learn through physical touch or object association, while maintaining compatibility with standard computer operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If a standard keyboard is used, then data entry is enabled, but learning curve difficulty increases for older individuals

Engineering Contradiction:

Improvedata entry capabilityVSAvoidlearning curve for older individuals

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The tactile button grid is designed to be self-explanatory through its physical layout and tactile feedback. Users can intuitively understand the device's functionality through physical interaction alone, eliminating the need to learn complex keyboard layouts or commands. The device serves itself by providing immediate physical feedback that guides users through the input process without requiring prior computer knowledge.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the abstract mechanical keyboard system with a more intuitive tactile button grid that provides physical feedback. This substitution maintains data entry capability while replacing the steep learning curve of traditional keyboards with an immediately understandable physical interface that older individuals can master quickly.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Extent of automation

If keyboard input is used, then computer operation is achieved, but physical engagement is reduced

Engineering Contradiction:

Improvecomputer operation capabilityVSAvoidphysical engagement for users

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

The tactile buttons are pre-configured with specific tactile feedback characteristics that prepare users for successful interaction. The physical design anticipates user needs by providing immediate feedback upon contact, making the interaction more engaging and less abstract compared to traditional keyboard input, thereby increasing physical engagement while maintaining automation.

Inventive Principle:

Principle #10Preliminary action
