Side-Mounted Display for Wearable Data Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable electronic devices face challenges in providing high visibility, low power consumption, and easy data reading regardless of external light conditions, while also displaying smooth moving images and eye-friendly still images.
Innovation Solution
The design incorporates a housing with a first and second display portion, where the second display portion is positioned on the side surface and can be easily viewed without moving the wrist, using a combination of reflective and light-emitting elements to optimize visibility and reduce power consumption, and includes band attachment portions for wearability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display device is positioned on the front surface for easy viewing, then ease of operation is improved, but the device cannot provide high visibility and low power consumption simultaneously
Solution Approach 1:
The display is divided into two separate portions: a first display portion on the front surface for general viewing, and a second display portion on the side surface specifically for data display. This segmentation allows each portion to be optimized for its specific function, with the side display using reflective elements for low power consumption and the front display for general visibility.
Solution Approach 2:
A light guide is introduced as an intermediary component between the light-emitting element and the display portion. The light guide transmits light from the light-emitting element to the display portion, enabling the use of reflective elements that can function in both transmissive and reflective modes, thus achieving low power consumption while maintaining visibility.
2Use of energy by moving object
If reflective elements are used to reduce power consumption, then power consumption is reduced, but visibility in dark environments deteriorates
Solution Approach 1:
The display portion is designed to function in multiple modes: it can operate as a reflective display to save power during the day, and as a transmissive display with light-emitting elements for visibility in dark environments. The light guide enables this multi-functionality by being able to transmit light from the light-emitting element when needed, while also supporting reflective operation when power conservation is prioritized.
3Ease of operation
If display portion is positioned on side surface for easy viewing without wrist movement, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The display is segmented into two spatially separated portions located on different surfaces of the housing. The first display portion is on the front surface and the second display portion is on the side surface. This segmentation allows the side-display configuration that enables viewing without wrist movement while keeping the overall device structure manageable through modular design.
