Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-removable batteries in computer devices can hinder diagnostics and maintenance, as users cannot easily access or discharge malfunctioning batteries, leading to booting issues and requiring service center visits.
Innovation Solution
A computer system with embedded microcontroller circuitry that allows for isolating and discharging the battery, enabling external power sourcing and maintenance operations without physical access, using switch circuitry to control battery power states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is made non-removable to improve device integration and security, then device reliability and integration are improved, but ease of repair and maintenance deteriorate
Solution Approach 1:
The system enables self-service battery maintenance through automated isolation and discharge functions. The embedded controller allows users to perform battery diagnostics, isolation, and discharge operations without requiring physical battery removal or service center visits, letting the system serve its own maintenance needs
Solution Approach 2:
An embedded controller acts as an intermediary between the user and the battery. This controller provides a user interface and automated control mechanisms that enable battery maintenance operations through software commands rather than physical manipulation, mediating the interaction between user intent and battery state changes
2Reliability
If the battery is made non-removable to extend device usability, then device integration is improved, but ease of operation for battery access deteriorates
Solution Approach 1:
The patent replaces mechanical battery removal with electronic control mechanisms. Instead of physically accessing and removing the battery through mechanical means, users interact through a user interface that triggers electronic isolation and discharge sequences controlled by the embedded controller, substituting mechanical access with electronic control
3Manufacturing precision
If service center visits are required for battery diagnostics, then manufacturing precision is maintained, but loss of time increases
Solution Approach 1:
The system performs self-diagnosis and self-maintenance of the battery through the embedded controller. Users can initiate diagnostic routines, isolation sequences, and discharge operations locally through the device's user interface, eliminating the need to transport devices to service centers and significantly reducing the time required for battery-related troubleshooting and maintenance

AI summary
A chassis structure of an apparatus contains a battery. Charger circuitry is operable to provide charge to the battery. Discharge circuitry is operable to receive charge from the battery. Switch circuitry is coupled between the battery and each of the charger circuitry, the discharge circuitry, and a load. A connector at an exterior surface of the chassis couples the apparatus to a power supply. The switch circuitry is coupled to the connector via the charger circuitry. A first control activable at the exterior surface of the chassis structure is operable to generate, in response to being activated, a first control signal to request a first switch state wherein the battery is electrically coupled to the discharge circuitry. A controller circuit coupled to receive the first control signal from the first control and, based on the first control signal, to operate the switch circuitry to provide the first switch state.
