Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet computers with built-in, non-pluggable batteries pose challenges for users attempting to perform global resets, as they cannot easily remove the power source to troubleshoot issues, leading to increased maintenance costs and time-consuming processes.
Innovation Solution
A power switching system comprising a first power input port, a first power output port, a first linear regulator module, and a first switch module, which allows users to control the power signal by activating a switch module connected to the ground end, enabling the transformation and regulation of power signals for easy disconnection, facilitating global resets without physically removing the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery is built-in and non-pluggable to keep the tablet computer compact, then the structure is compact and integrated, but the user cannot easily remove the power source to perform global reset or troubleshooting
Solution Approach 1:
The power supply system is segmented into modular components: a removable battery pack, a power switching system with separate switch module, and a control module. This segmentation allows the battery to remain built-in for compactness while enabling easy removal of power through the switch module, resolving the contradiction between compact structure and ease of power removal.
Solution Approach 2:
A power switching system acts as an intermediary between the battery and the computer system. The switching system includes a switch module that can disconnect power without requiring physical battery removal, serving as a mediator that enables easy power removal while maintaining the built-in battery structure for compactness.
2Productivity
If the battery is built-in and non-pluggable, then the tablet computer structure is compact, but maintenance cost and time increase due to professional intervention required
Solution Approach 1:
The power switching system enables users to perform self-service troubleshooting by allowing easy power disconnection through the switch module. Users can independently execute global resets and basic diagnostics without requiring professional maintenance center intervention, thereby improving troubleshooting efficiency and reducing maintenance costs.
Solution Approach 2:
The power switching system serves as an intermediary tool that bridges the gap between the sealed battery structure and user accessibility. It provides users with the capability to easily disconnect power for troubleshooting purposes, making maintenance operations accessible to end users rather than requiring professional intervention.
3Ease of operation
If a power switching system is added to enable easy power removal, then user accessibility for troubleshooting is improved, but the device complexity increases
Solution Approach 1:
The power switching system is divided into distinct functional modules: a switch module for power disconnection, a control module for system coordination, and integration with the existing battery management system. This modular segmentation allows the system to add power removal functionality while maintaining manageable complexity through clear module boundaries and independent functions.
