Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional input methods are used for mobile device operation, then device control functionality is maintained, but accessibility for individuals with physical impairments deteriorates
Solution Approach 1:
The patent replaces traditional mechanical input methods (buttons, keyboards, touchscreens) with an electrooculographical sensing system that detects eye movements and converts them into device control commands. This substitution enables physically impaired users to operate mobile devices through eye movements alone, fundamentally improving accessibility without compromising control functionality
Solution Approach 2:
The patent introduces electrooculographical sensors as an intermediary between the user's eye movements and the mobile device control system. These sensors detect corneo-fundal potential changes caused by eye movements and translate them into actionable commands, serving as a bridge that enables communication between users with physical impairments and the device interface
2Adaptability or versatility
If electrooculographical sensors are added to enable eye movement control, then accessibility for physically impaired users is improved, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional system where the mobile device serves both its traditional communication functions and new accessibility control functions through integrated electrooculographical sensing. The device can operate as a standard mobile phone while simultaneously providing eye-movement-based control, eliminating the need for separate specialized equipment and reducing overall system complexity
Solution Approach 2:
The patent merges the electrooculographical sensing system with the mobile device itself, combining accessibility features with standard communication functionality in a single integrated unit. This integration allows the device to provide both traditional operations and eye-movement control without requiring separate systems, thereby managing complexity while enhancing accessibility
