Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a stationary user interface is provided on the processing device, then the operator can access device information, but the operator must divert attention from the processing area to the display device
Solution Approach 1:
A portable user interface device (smartphone, tablet, or wearable) acts as an intermediary between the processing device and the operator. The portable device receives device status information from the processing device via wireless communication and displays it in the operator's field of vision, eliminating the need for the operator to physically move to a stationary display device while still providing access to all necessary information.
Solution Approach 2:
The user interface is moved from a fixed spatial location (stationary display on the processing device) to a mobile platform that can be positioned in the operator's field of vision. This dimensional change allows information to be displayed in the same spatial plane as the processing area, eliminating the need for attention diversion while maintaining information accessibility.
2Ease of operation
If the user interface is made portable and displayed in the operator's field of vision, then the operator can monitor device status without diverting attention, but the interface complexity increases
Solution Approach 1:
The portable user interface leverages existing multi-functional devices (smartphones, tablets, wearables) that already possess display, wireless communication, and processing capabilities. By utilizing these universal devices rather than designing a specialized interface from scratch, the system achieves portability and field-of-vision display while minimizing the addition of complex proprietary components.
Solution Approach 2:
The portable device utilizes its own built-in resources (processor, display, battery, wireless module) to present device status information. The processing device simply transmits data via wireless communication, while the portable device independently handles display rendering and user interaction, distributing the system complexity across existing self-sufficient components rather than concentrating it in one complex interface unit.
3Ease of operation
If gesture recognition is implemented for control, then the operator can control the device without stationary input devices, but the system complexity and processing requirements increase
Solution Approach 1:
Physical mechanical input devices (buttons, knobs, switches on the processing device) are replaced with gesture recognition technology. The portable device's camera or sensor array detects hand and body gestures, translating them into control commands wirelessly transmitted to the processing device. This substitution eliminates the need for operators to physically approach or touch the processing device, providing contactless control while utilizing the portable device's existing sensing and processing capabilities.
Solution Approach 2:
The portable device serves as an intermediary that captures gestures via its camera or sensors, processes the gesture data using its own processor or cloud-based services, and transmits the interpreted control commands to the processing device. This intermediary approach distributes the gesture recognition complexity across the portable device's existing computational resources rather than requiring the processing device to have built-in gesture recognition capabilities.
4Adaptability or versatility
If the portable user interface is used for both information display and control input, then the interface versatility improves, but the reliability requirements increase
Solution Approach 1:
The portable user interface implements bidirectional wireless communication with the processing device, receiving device status information for display and transmitting control commands based on operator input. The system includes feedback mechanisms where the processing device acknowledges received commands and confirms status changes, ensuring reliable two-way communication while maintaining interface versatility for both monitoring and control functions.
