Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional keyboards use fixed key layouts, then manufacturing and usage are simple, but adaptability to different functions and user needs is limited

Engineering Contradiction:
Improvekey layout flexibilityVSAvoidkeyboard configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The keyboard is divided into modular key units that can be independently configured and rearranged. Each key or group of keys can be separately designed, manufactured, and positioned to create different layouts according to user needs or application requirements, enabling adaptability without requiring complete redesign of the entire keyboard.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The keyboard layout can be dynamically changed or reconfigured based on different usage scenarios. The system allows for flexible arrangement of keys, potentially through movable or repositionable key modules, enabling the same physical keyboard to adapt to different functions such as programming, music composition, or general typing.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If keyboards have large desktop footprints, then key size and layout options are improved, but workspace disruption and workflow interruption occur

Engineering Contradiction:
Improvetyping comfortVSAvoidkeyboard footprint
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The keyboard can be segmented into multiple independent key modules that can be arranged in different configurations. This allows the keyboard to maintain adequate key size for comfortable typing while reducing the overall footprint by optimizing the spatial arrangement of these modular units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The keyboard design may utilize three-dimensional space more effectively, potentially stacking keys vertically or arranging them in non-traditional patterns that maintain typing comfort while reducing the horizontal footprint on the desktop surface.

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

3Weight of moving object

If keyboards are designed for portability, then mobility and convenience are improved, but key size and input accuracy are reduced

Engineering Contradiction:
Improvekeyboard weightVSAvoidkey input accuracy
Core Design Contradiction:
Weight of moving objectVSMeasurement precision

Solution Approach 1:

Different regions of the keyboard can have different characteristics optimized for their specific functions. For example, frequently used keys can be larger or have enhanced feedback mechanisms, while less frequently used keys can be smaller, allowing the keyboard to maintain portability while preserving input accuracy where it matters most.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The keyboard may incorporate alternative input mechanisms beyond traditional mechanical switches, such as capacitive touches, optical sensors, or magnetic actuators, which can provide precise input detection with smaller form factors and reduced weight.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If conventional keyboards use standard layouts, then compatibility is maintained, but security against unauthorized access is insufficient

Engineering Contradiction:
Improveaccess control capabilityVSAvoidsecurity system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The keyboard can be divided into secure and non-secure zones, or keys can be individually secured with different authentication requirements. This allows granular control over which keys require authentication and what level of authentication is needed, enhancing security without requiring complete system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The keyboard can integrate with biometric authentication systems, fingerprint readers, or other security mechanisms as intermediary components. This allows the keyboard to inherit security capabilities from existing systems rather than implementing complex security measures from scratch.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An information handling system keyboard liquid crystal display (LCD) presents visual images of key values through adaptive modular keys placed over the LCD and having a transparent key cap. Each adaptive modular key has a base portion that magnetically couples to the LCD and an upper portion slidingly engaged in the base portion biased to a raised position and depressing to indicate an input by contacting the LCD. A controller detects the adaptive modular key positions to automatically determine visual images for presentation at the LCD under each key.
