Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a mechanical gauge is used for tire pressure monitoring, then the system structure is simple, but the feedback timeliness and driver awareness are insufficient
Solution Approach 1:
The patent replaces the traditional mechanical gauge system with an electronic monitoring system that includes pressure sensors, transceivers, and a wearable device with haptic feedback. This substitution enables real-time wireless transmission of tire pressure data and provides timely tactile feedback to the driver, resolving the contradiction between information feedback quality and system complexity.
Solution Approach 2:
The patent introduces a wearable device as an intermediary between the tire pressure monitoring system and the driver. This intermediary receives pressure data wirelessly and converts it into haptic feedback signals, serving as a mediator that translates mechanical pressure information into intuitive tactile notifications for the driver, thereby improving information feedback without requiring direct mechanical interaction.
2Reliability
If real-time tire pressure monitoring is implemented, then safety and responsiveness are improved, but the system complexity and cost increase
Solution Approach 1:
The patent divides the monitoring system into separate functional modules: pressure sensors mounted on each tire, a transceiver unit for wireless communication, and a wearable device for feedback. This segmentation allows each component to perform its specific function independently, improving overall system reliability while managing complexity through modular design.
Solution Approach 2:
The wearable device serves multiple functions: it receives wireless pressure data, processes the information, and provides haptic feedback. By making the wearable device multi-functional, the system achieves reliable real-time monitoring without adding separate dedicated components for each function, thereby managing system complexity.
3Ease of operation
If mechanical gauges are used, then the device structure is simple, but the ease of operation and driver convenience are reduced
Solution Approach 1:
The system enables self-service monitoring by automatically detecting tire pressure through sensors and providing feedback to the driver without requiring manual gauge attachment or reading. The wearable device continuously monitors pressure levels and alerts the driver through haptic feedback, making the system convenient to operate while managing complexity through automation.
Solution Approach 2:
The patent implements a closed-loop feedback system where pressure sensors continuously monitor tire pressure, transmit data wirelessly to the wearable device, and provide immediate haptic feedback to the driver. This continuous feedback mechanism enhances ease of operation by providing real-time information without manual intervention, while the automated feedback loop manages system complexity.
