Wrist-worn Device Display Mode Matching via Optical Wristband Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wrist-worn devices struggle to match their display modes with different styles of wristbands, affecting user experience as users often need to change wristbands to match their clothing, leading to inconsistent device styles.
Innovation Solution
A display method that uses a light source to emit a detection light, which is reflected by the wristband and identified by a light identification unit, allowing the controller to generate a screen display control signal to match the display mode with the wristband's style, ensuring a unified overall style.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display mode is fixed and cannot be adjusted, then the device structure is simple, but the adaptability to different wristband styles is poor
Solution Approach 1:
The wrist-worn device automatically detects the wristband style through the light identification unit and autonomously adjusts the display mode without user intervention. The system serves itself by using the optical properties of the wristband as input to trigger corresponding display mode changes, eliminating the need for manual selection or complex configuration interfaces.
Solution Approach 2:
The display mode parameters (such as color theme, icon style, font style) are dynamically changed based on the detected wristband optical properties. The controller adjusts display parameters according to the identified wristband style, enabling the display to adapt to different wristband styles through parameter modification rather than structural change.
2Adaptability or versatility
If manual selection of display modes is required, then the device can adapt to different styles, but the ease of operation is reduced
Solution Approach 1:
The system automatically performs the style-matching function without requiring user operation. The light identification unit continuously or periodically detects the wristband style, and the controller automatically switches the display mode accordingly, making the adaptation process transparent and effortless for the user.
Solution Approach 2:
The system establishes a feedback loop where the light identification unit detects wristband optical properties, the controller processes this information to identify the wristband style, and then adjusts the display mode based on this feedback. This closed-loop control ensures the display mode continuously matches the current wristband style.
3Adaptability or versatility
If multiple display modes are added to match different wristbands, then the adaptability improves, but the device complexity increases
Solution Approach 1:
Instead of adding complex hardware components, the solution changes display parameters (color schemes, themes, icon styles) to achieve different display modes. The controller simply selects from a set of pre-defined display parameter configurations based on the detected wristband style, keeping the control logic relatively simple while achieving high adaptability.
Solution Approach 2:
The light identification unit serves multiple functions: it can detect wristband style through optical properties and potentially other characteristics. This multi-functional component reduces the need for separate detection mechanisms for each feature, thereby controlling overall device complexity while enhancing adaptability.
