Battery-Integrated Reset Control Module for Portable Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face malfunctions due to complex system operations and design defects, requiring effective reset procedures that are inconvenient and limited by the need for additional reset buttons, especially when batteries are non-removable.
Innovation Solution
A reset control device with a signal generating unit and control module installed in the battery, which disconnects and reconnects the power supply link between the battery and system circuit according to a predefined rule, allowing for a controlled reset without the need for a dedicated reset button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reset button is added to trigger restart of operating system, then the reset procedure can be achieved, but the device complexity increases and external design flexibility is reduced
Solution Approach 1:
The patent merges the reset function with the existing power button by detecting specific pressing patterns (duration, frequency, combination with other keys). This eliminates the need for a separate reset button, reducing device complexity while maintaining reset functionality through intelligent signal processing of the power button presses.
Solution Approach 2:
The power button is designed to serve multiple functions: normal power on/off, sleep mode, and reset operation. By detecting different pressing patterns (e.g., holding for specific duration, pressing in combination with other keys), the single power button achieves multi-functionality, eliminating the need for dedicated reset hardware.
2Reliability
If a reset button is added to trigger restart of operating system, then the reset procedure can be achieved, but the external design flexibility is reduced
Solution Approach 1:
The reset function is merged into the existing power button, eliminating the need for an additional physical button on the device exterior. This preserves external design flexibility while maintaining reset capability through software-based detection of specific power button pressing patterns.
Solution Approach 2:
The power button serves universal purposes including power control, sleep mode, and reset operations. This multi-functionality approach allows the device to maintain reset capability without adding external buttons, thus preserving design flexibility and adaptability.
3Reliability
If the battery is temporarily disconnected to execute restart procedure, then the system circuit can be reset, but the operation convenience is reduced and portability is compromised
Solution Approach 1:
The patent introduces a control module as an intermediary between the battery and system circuit. This module can selectively disconnect power to specific components (not the entire system) based on detected reset signals, enabling system reset while maintaining battery connection and overall operational convenience.
Solution Approach 2:
The power supply system is segmented into controllable sections through the control module. Instead of disconnecting the entire battery, the module can isolate specific circuits or components requiring reset while maintaining power to other parts of the system, thus enabling targeted resets without compromising overall operation convenience.

AI summary
A reset control device for an electronic device having a battery for providing operating power for a system circuit is provided. The reset control device includes a signal generating unit for generating a control signal, and a control module installed in the battery and coupled to the signal generating unit for disconnecting a power supply link between the battery and the system circuit for a predetermined duration and recovering the power supply link, when the control signal conforms to a predefined rule, so as to reset the system circuit.
