Solution Overview
Problem
Existing electronic labels using electronic paper displays (EPDs) face high energy consumption and slow image updates when attempting to dynamically change images, limiting their ability to attract attention and differentiate products visually.
Innovation Solution
An electronic label design with a light-conducting side wall that emits light to draw attention dynamically, controlled by the label's electronics, while the EPD displays static information, reducing energy consumption through efficient light guidance and emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the EPD displays dynamic images by repeatedly updating the image, then the image content can change, but energy consumption increases significantly and the image update becomes visible to the viewer
Solution Approach 1:
The label is divided into two distinct functional parts: the front wall with EPD for static information display, and the side wall with light guide for dynamic attention-drawing. This segmentation allows each part to perform its optimized function without compromising the other.
Solution Approach 2:
The attention-drawing function is moved from the front display surface to the side wall dimension. Instead of updating the EPD content dynamically, the system uses light emission from the side wall to attract attention, separating the information display function from the attention-drawing function.
2Reliability
If the EPD refreshes the display frequently to maintain image quality, then the image remains clear, but energy consumption increases and stuttering becomes visible
Solution Approach 1:
The light source on the side wall operates periodically rather than continuously, emitting light in controlled intervals to draw attention without requiring constant EPD refreshes. This periodic operation reduces energy consumption while maintaining effectiveness.
3Adaptability or versatility
If a light source is added to enable dynamic attention-drawing, then the label can attract attention, but the device complexity increases
Solution Approach 1:
The light guide function is merged with the side wall structure itself. The side wall is designed with light-conducting properties and integrated optical elements, combining the structural support function with the light guidance function in a single component.
Solution Approach 2:
The side wall serves multiple functions: structural support for the housing, light guidance for attention-drawing, and potential information display. This multi-functionality reduces the need for separate components and reduces overall device complexity.
