Automated Analysis Device Lifetime Display Switching for Replacement Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analysis devices struggle to intuitively convey the current use status and replacement time of limited-life members, such as light sources, due to continuous display formats that lack accuracy and clarity, especially at the beginning of the lifetime prediction.
Innovation Solution
The device incorporates a control unit to predict the remaining lifetime of limited-life members and switches the display method based on predefined reference values, offering multiple display options such as ratio or number of days to enhance user understanding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the remaining lifetime is continuously displayed in a single display format (e.g., remaining hours or number of remaining days), then the display is simple and consistent, but it becomes difficult for users to grasp the current use status or specific replacement time
Solution Approach 1:
The display unit dynamically switches between different display formats (remaining hours, number of remaining days, replacement timing) based on the current lifetime status of the limited-life member. This allows the system to adapt the display format to the current operational phase, making it easier for users to grasp the current use status without manual calculation while avoiding unnecessary complexity when not needed
Solution Approach 2:
The system changes the display parameter format based on the remaining lifetime threshold. When the remaining lifetime exceeds a predetermined threshold, it displays in one format (e.g., remaining hours); when it falls below the threshold, it switches to another format (e.g., number of remaining days or replacement timing). This parameter change approach optimizes user understanding at different lifecycle stages
2Measurement precision
If the number of remaining days is consistently displayed from the beginning, then the display is intuitive, but the prediction accuracy is not high especially at the beginning
Solution Approach 1:
The system selects different display parameters based on the remaining lifetime stage. In the early stage with high remaining lifetime, it displays remaining hours for accurate prediction. In the later stage with low remaining lifetime, it switches to number of remaining days for intuitive understanding. This conditional parameter selection resolves the contradiction between accuracy and intuitiveness
3Measurement precision
If the remaining hours are consistently displayed from the beginning, then the prediction accuracy is high, but it requires users to calculate when the lifetime will end
Solution Approach 1:
The display unit dynamically adapts the information presented based on user needs at different stages. Early in the lifecycle, it shows remaining hours for accuracy. As the lifecycle progresses and replacement becomes imminent, it automatically calculates and displays the number of remaining days or replacement timing, eliminating the need for user calculation while maintaining accuracy
Solution Approach 2:
The system performs the calculation of replacement timing automatically based on the remaining lifetime data. Instead of requiring users to manually calculate when replacement is needed, the system self-services by computing and displaying the replacement timing information directly, making the device easier to operate while maintaining prediction accuracy
