Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable chargers lack the capability for fast charging and are not suitable for large electronic devices, leading to resource wastage due to the need for separate chargers for different power requirements.
Innovation Solution
A power supply device comprising two modular conversion units that can be separated or combined, allowing for portable low-power charging and high-power indoor use, with the combined module enabling faster charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If small chargers are designed for portability with light weight and small volume, then ease of carrying is improved, but output energy decreases and fast charging capability is lost
Solution Approach 1:
The charger is divided into two separate conversion modules: a first conversion module for portable use with low power consumption and small volume, and a second conversion module for indoor use with high power output capability. Each module can function independently, allowing users to carry only the portable module when needed while utilizing both modules together at home for fast charging.
2Power
If large chargers are designed for fast charging with large output power, then charging speed is improved, but volume and weight increase making them non-portable
Solution Approach 1:
The high-power charging function is segmented into a separate second conversion module designed for indoor use, while the first conversion module maintains portability. The modular design allows the heavy, high-power module to remain at home while the lightweight portable module provides sufficient charging for mobile devices during travel.
3Adaptability or versatility
If separate chargers are purchased for different power requirements, then adaptability to different devices is improved, but resource waste occurs due to multiple chargers
Solution Approach 1:
The charger system provides multiple usage modes: the first conversion module alone for portable charging, the second conversion module alone for high-power indoor charging, and both modules combined for enhanced charging capability. This multi-functional design replaces the need for multiple separate chargers, reducing resource waste while maintaining adaptability to various power requirements.
