Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-operated devices often supply power parameters such as voltage and current that are not suitable for receiving devices, leading to inconsistent configuration over time, potentially damaging either the source or sink, as the battery discharges and power requirements change.
Innovation Solution
A battery-operated device provides a bounded voltage range within a determined minimum and maximum value, using a controller to adjust the output voltage and reported state based on the battery's voltage state and requested power parameters, employing converters like buck or boost converters to maintain consistent power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If battery-operated devices supply power parameters based on battery discharge state, then power transfer capability is improved, but voltage consistency deteriorates
Solution Approach 1:
The patent implements dynamic voltage adjustment by establishing a bounded voltage range that adapts to the battery's discharge state. The controller dynamically modifies the operating voltage within this bounded range based on real-time battery conditions, allowing the system to maintain voltage consistency while adapting to changing power requirements during battery discharge cycles.
Solution Approach 2:
The patent changes the voltage parameter by implementing a bounded voltage range instead of a fixed voltage. The controller adjusts the operating voltage within this bounded range based on the battery's state of charge and discharge rate, enabling the system to maintain stable power transfer while accommodating natural voltage variations during battery discharge.
2Stability of the object's composition
If voltage conversion is implemented to maintain consistent voltage, then voltage consistency is improved, but device complexity increases
Solution Approach 1:
The patent applies partial voltage conversion by implementing a bounded voltage range instead of complete voltage regulation. The controller allows voltage to vary within acceptable bounds rather than maintaining a single fixed voltage, reducing the need for complex conversion circuitry while still preventing damage to connected devices.
Solution Approach 2:
The patent introduces a controller as an intermediary between the battery and the power output. This controller monitors battery voltage and adjusts the output accordingly, acting as a mediator that simplifies the overall system by using software-based control rather than complex hardware conversion circuits.
3Reliability
If bounded voltage range is implemented, then reliability is improved, but power transfer efficiency deteriorates
Solution Approach 1:
The patent implements dynamic voltage adjustment by establishing a bounded voltage range that adapts to the battery's discharge state. The controller dynamically modifies the operating voltage within this bounded range based on real-time battery conditions, allowing the system to maintain voltage consistency while adapting to changing power requirements during battery discharge cycles.
