Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic shelf labels face challenges in reliability due to frequent collisions, lack of protective structures, high maintenance costs due to short battery life, and limited modularity, especially in customized installations and environments with high usage demands.
Innovation Solution
The electronic shelf label incorporates a protective sheath around the screen, a press-resistant gap between the lens and screen, and uses a lithium-manganese pouch battery with improved stability and longevity, along with a modular circuit board design for enhanced durability and cost-effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective structure is added around the screen, then the anti-impact and anti-pressing capabilities are improved, but the device complexity increases
Solution Approach 1:
The protective sheath is nested around the screen, forming a protective cavity that accommodates the screen while providing cushioning. The lens is nested within the protective sheath structure, with the press-resistant gap integrated into the design. This nested arrangement protects the screen from external forces without requiring separate protective components, thereby improving reliability while controlling device complexity.
Solution Approach 2:
The protective sheath is designed with cushioning material that deforms under external force to absorb impact before it reaches the screen. The press-resistant gap is pre-designed between the lens and screen to prevent direct contact during pressing events. This beforehand cushioning approach protects the screen from damage while maintaining a relatively simple overall structure.
2Duration of action of moving object
If a button battery is used, then the device can be powered, but the service life is short due to self-discharge rate
Solution Approach 1:
The patent changes the battery type from button battery to lithium-manganese pouch battery, which has fundamentally different electrical and chemical parameters. The lithium-manganese pouch battery offers lower self-discharge rate, higher energy density, and longer service life, directly addressing the energy loss and duration issues while maintaining compatibility with the device's power requirements.
3Adaptability or versatility
If the circuit board size is limited due to many electronic components, then the device can be compact, but the modularity and customization capability are reduced
Solution Approach 1:
The circuit board is segmented into functional modules, with the power supply module using a lithium-manganese pouch battery that can be independently configured. This segmentation allows different battery capacities and circuit configurations to be used based on customization requirements without increasing the overall device volume, as each module is optimized for its specific function.
Solution Approach 2:
The lithium-manganese pouch battery serves multiple functions: it provides power supply, acts as a structural element within the protective sheath, and enables thermal management. This multi-functionality reduces the need for separate components, allowing the circuit board to maintain compact size while supporting modular design and customization through standardized interfaces.

AI summary
The present disclosure provides an electronic shelf label, including a rear shell (1), a screen (4), a protective sheath (5) and a lens (6). The protective sheath (5) is sheathed on an outer side of the screen (4), an accommodation groove (101) is formed on the rear shell (1), and the screen (4) is disposed in the accommodation groove (101). The lens (6) is disposed to cover a groove opening of the accommodation groove (101) and is connected to an edge of the rear shell (1). A portion of the protective sheath (5) located at an edge of a display port of the screen (4) is supported between the lens (6) and the screen (4), so that a press-resistant gap (8) is reserved between the lens (6) and the screen (4). The present disclosure solves the technical problems that the electronic shelf label is easy to be damaged and the use effect is poor.
