Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bar screen display systems in business places consume excessive power during business and non-business hours, leading to increased operational costs for merchants, especially when the number of terminals is large.
Innovation Solution
A bar screen control circuitry that includes a power supply control circuitry and a processor to detect preset starting and closing times, controlling the bar screen to enter a first working state during business hours and a closed state during non-business hours, with optional detection of people in the area to adjust the power state, using a Real-Time Clock chip, switch circuitry, and detection devices like infrared sensors to manage power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bar screen operates continuously during all hours, then the display function is always available, but the power consumption increases excessively
Solution Approach 1:
The bar screen control circuitry implements periodic operation by activating the display during preset business hours and shutting down during non-business hours. The power supply control circuitry receives timing signals from a real-time clock to periodically switch between working state and closed state, achieving energy savings while maintaining display availability during operational hours.
2Use of energy by moving object
If the bar screen shuts down during non-business hours, then power consumption is reduced, but the display cannot respond to unexpected customer needs
Solution Approach 1:
The system incorporates occupancy detection feedback through infrared sensors or other detection devices that monitor whether customers are present in the shopping area. When customers are detected, the system activates the bar screen display even during non-business hours, ensuring adaptability to actual usage needs while maintaining energy efficiency during truly unattended periods.
Solution Approach 2:
The bar screen control circuitry dynamically adjusts its operational state based on real-time occupancy conditions. The system transitions between closed state, working state, and second working state (different brightness levels) according to detected customer presence, making the display adaptable to varying operational requirements while optimizing power consumption.
3Illumination intensity
If the bar screen operates at full power during business hours, then the display quality is optimal, but the operational costs increase
Solution Approach 1:
The system implements local quality adjustment by providing different brightness levels in different operational contexts. During periods with detected customer occupancy, the display operates at full brightness (second working state) for optimal visibility. During periods without occupancy, the display reduces to lower brightness (first working state), reducing energy consumption while maintaining functional operation.
