Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-powered automated movable screens face high energy consumption issues due to frequent waking of the radio receiver, especially when exposed to unrelated transmitters, leading to reduced autonomy and increased costs in battery-powered systems.
Innovation Solution
A method utilizing a bipolar electric source comprising a low-capacity rechargeable cell and a non-rechargeable cell, where the rechargeable cell only supplies the control means, and the non-rechargeable cell supplies the motor, with a switching mechanism to optimize energy use based on available energy levels and signal reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the radio receiver is placed in sleep mode with periodic wakening to identify radio signals, then energy consumption is reduced, but the receiver is unnecessarily wakened too frequently by unrelated transmitters, decreasing autonomy
Solution Approach 1:
The power supply is segmented into two independent sources: a rechargeable cell dedicated to the control means (radio receiver) and a non-rechargeable cell dedicated to the motor. This segmentation allows the radio receiver to operate with lower power requirements from the rechargeable cell, enabling longer autonomy even with frequent wake-ups, while the motor is powered by the non-rechargeable cell.
Solution Approach 2:
The invention changes the power supply parameters by introducing a dual-cell configuration with different cell types (rechargeable vs. non-rechargeable) assigned to different functional components. This parameter change allows the radio receiver to maintain frequent wake-up cycles for signal detection while preserving overall system autonomy, as the high-consumption motor operations are isolated to the non-rechargeable cell.
2Device complexity
If a single battery-powered source supplies both the motor and radio receiver, then the system is simpler, but the rechargeable cell must be dimensioned to completely supply all electric equipment, leading to large and costly dimensioning
Solution Approach 1:
The power supply system is divided into two separate cells with distinct functions: the rechargeable cell supplies only the control means (low power consumption), while the non-rechargeable cell supplies the motor (high power consumption). This segmentation allows each cell to be optimally sized for its specific load, avoiding the need for an oversized rechargeable cell that would be required to power both components.
Solution Approach 2:
The dual-cell power supply system provides multi-functionality by enabling the rechargeable cell to handle intermittent low-power operations (radio receiver in sleep/wake mode) while the non-rechargeable cell handles high-power operations (motor activation). This universal approach optimizes the overall system by matching each power source to its most efficient operational role.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces energy consumption and extends battery life by minimizing the rechargeable cell's role to only powering the control means, allowing the non-rechargeable cell to handle motor operations, thereby reducing the overall dimensioning and cost of the energy source.
