Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices face inconvenience due to limited battery replacement options and the need for external AC power when battery packs are exhausted or obsolete, especially outdoors without access to charging facilities.
Innovation Solution
A battery replaceable pack with a containing casing, protecting circuit board, and connector that allows users to insert common marketable batteries, featuring a charging circuit and detecting circuit to differentiate between rechargeable and non-rechargeable batteries, preventing overcharging and ensuring safety by controlling charging based on battery type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users buy new rechargeable lithium battery packs from the manufacturer or ask the battery manufacturer to replace the battery cells, then the portable electronic device can continue to be used, but the cost increases and the portability is reduced due to needing to carry the device to the manufacturer
Solution Approach 1:
The battery pack enables users to perform battery replacement and charging operations independently without needing to visit a manufacturer or service center. The self-contained design with replaceable batteries and integrated charging circuit allows users to maintain their device's power supply anywhere, transforming a service-dependent scenario into a self-service solution.
2Reliability
If users buy a universal battery-type emergent power supply device with both AC and DC, then power can be supplied when battery is exhausted, but the device becomes big and heavy reducing portability
Solution Approach 1:
The battery pack is designed to accept multiple types of batteries (rechargeable lithium batteries and non-rechargeable batteries) and can function as both a power source and a charging device. The detecting circuit automatically identifies battery type and adjusts charging parameters accordingly, making the device universally compatible while maintaining portability.
3Productivity
If the charging circuit continuously charges the battery without detection, then power can be continuously supplied, but overheating or burning occurs when charging non-rechargeable batteries
Solution Approach 1:
The detecting circuit continuously monitors battery parameters (voltage, current, temperature) and provides feedback to the charging circuit. Based on this feedback, the charging circuit automatically adjusts charging current and voltage, and can terminate charging when appropriate conditions are met, preventing overheating and burning while maintaining efficient charging.

AI summary
A battery replaceable pack for a portable electronic device is provided. The battery replaceable pack includes a containing casing, at least one battery, a protecting circuit board, and a connector. The protecting circuit board has a charging circuit and a detecting circuit electrically connected with each other. When the portable electronic device is connected to an external power supply, the charging circuit performs a testing charge on the battery and the detecting circuit detects the status of the battery. The detecting circuit detects whether the battery is rechargeable so as to assure the battery safety. An electronic device with the battery replaceable pack is also disclosed.
