Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If battery power supplying mode is used, then the electronic shelf label can operate independently, but the service life is limited by battery capacity
Solution Approach 1:
The patent removes the battery component from the electronic shelf label system entirely, extracting the energy storage function and replacing it with a solar panel-based energy harvesting approach. This eliminates the limitation of battery capacity while maintaining independent operation capability.
Solution Approach 2:
The electronic shelf label becomes self-sufficient by incorporating a solar panel that automatically harvests energy from the environment. The system serves itself by converting light energy into electrical energy to power its operations, eliminating the need for external battery replacement or charging.
2Duration of action of moving object
If active power supplying mode is used, then continuous power can be supplied, but complicated wiring and assembling operations are required
Solution Approach 1:
The patent extracts and eliminates the complex wiring system by removing the need for connection to external active guide rails. The DC power source function is integrated directly into the shelf label through the solar panel, eliminating all associated wiring and assembling operations.
Solution Approach 2:
The system generates its own power independently through the solar panel without requiring connection to external power infrastructure. This self-powered approach eliminates the need for complicated wiring to active guide rails while maintaining continuous power supply capability.
3Power
If active power supplying mode is used, then DC power source can be introduced, but safety is compromised
Solution Approach 1:
The patent removes the external DC power source connection and replaces it with an integrated solar panel system. This extraction of the external power connection eliminates the safety risks associated with exposed wiring and connections while maintaining the ability to supply DC power to the electronic components.
4Power
If active power supplying mode is used, then power can be supplied, but cost increases
Solution Approach 1:
The patent eliminates the need for expensive active guide rail infrastructure and associated wiring by extracting the power supply function and implementing it through an inexpensive solar panel integrated directly into the shelf label.
Solution Approach 2:
The system generates its own power through the solar panel without requiring investment in external power infrastructure. This self-powered approach significantly reduces manufacturing and installation costs compared to active power supplying systems that require DC power sources and wiring infrastructure.
5Power
If active power supplying mode is used, then power can be supplied, but the volume of the shelf label increases
Solution Approach 1:
The patent removes the need for external power connection components and wiring that would increase volume. The solar panel is integrated directly into the shelf label structure, providing power supply functionality without the bulk associated with active power supplying systems.
