Illumination Color Changer for Measuring Device State Indication
Solution Overview
Problem
Conventional measuring devices face difficulties in displaying information effectively, especially in low-light conditions, due to the limitations of backlights, which can make it hard for users to determine the measurement mode or operation state without reading the display.
Innovation Solution
Incorporating an illumination color changer that adjusts the color of the backlight based on the measurement mode, operation state, or usage conditions, allowing users to identify the mode or state through color cues without relying on display text or icons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a backlight is used to illuminate the display device, then the display becomes visible in dark places, but it remains difficult to read information under certain conditions such as poor eyesight
Solution Approach 1:
The patent applies color changes by using an illumination color changer that emits different colored lights (e.g., red, green, blue) based on the measurement mode or operation state. This allows users to quickly identify the current state through color perception rather than reading text or icons, thereby improving readability reliability for users with poor eyesight while maintaining display visibility through backlight illumination.
2Illumination intensity
If the backlight emits light to the display device, then information is easier to read in dark places, but additional information about measurement state is lost
Solution Approach 1:
The illumination color changer encodes measurement state information into the color of the emitted light. Different colors represent different measurement modes or operation states, allowing the system to convey additional information without requiring users to read text or icons on the display, thus preventing information loss while maintaining visibility.
Solution Approach 2:
The illumination color changer acts as an intermediary that translates measurement state information into visual color cues. This intermediary component bridges the gap between the display system and the user, providing intuitive state indication through color perception rather than requiring direct reading of display content.
3Illumination intensity
If the backlight is used for illumination, then the display is visible, but the device complexity increases due to additional components
Solution Approach 1:
The illumination color changer serves multiple functions: it provides display illumination like a traditional backlight, conveys measurement state information through color changes, and indicates operation modes. By combining these functions into a single component, the system avoids the complexity of separate illumination and information display systems while maintaining visibility and providing additional state information.
