Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual sticker updates are used to change device status information, then the device can provide current information about gas sensor configuration and compliance, but the process requires high time expenditure and manual effort
Solution Approach 1:
The patent replaces the mechanical system of manual sticker application and removal with an electronic display system. The control unit dynamically updates the second display unit to show current device status information, eliminating the need for physical sticker changes and reducing time expenditure significantly.
Solution Approach 2:
The device performs self-updating of status information through the control unit, which automatically detects changes in device configuration and compliance status and updates the display accordingly. This eliminates the need for manual intervention to keep information current.
2Reliability
If stickers are manually updated to reflect changes in gas sensor configuration, then the information can be kept current, but the process incurs additional costs and high time expenditure
Solution Approach 1:
The patent replaces manual sticker updates with an electronic display system controlled by a control unit. This substitution eliminates the costs associated with producing and applying physical stickers while improving the reliability of information through automatic updates based on actual device status.
Solution Approach 2:
The control unit continuously monitors device status and provides feedback to the second display unit, ensuring that the displayed information always reflects the current state of the device. This feedback mechanism guarantees information accuracy without requiring manual verification or updates.
3Ease of operation
If stickers are used to mark device information, then the information is visible to users, but the information cannot be changed or can only be changed with great effort
Solution Approach 1:
The patent transforms the static information presentation of physical stickers into a dynamic electronic display system. The second display unit can be updated in real-time by the control unit to reflect changes in device status, configuration, or compliance information, providing both visibility and adaptability.
Solution Approach 2:
The electronic display system serves multiple functions: it displays device status information, compliance information, and can be updated dynamically for different configurations. This universal display solution replaces the single-function static stickers with a multi-functional adaptive system.
