Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable battery chargers are inefficient and cumbersome for jump-starting vehicles, particularly for elderly or disabled individuals, and lack features for rapid recharging within a vehicle and easy assembly/disassembly without specialized tools.
Innovation Solution
A portable battery charger system comprising a base assembly with a rechargeable battery, air compressor, and fan assembly, along with a removable head assembly housing another rechargeable battery, electrical outlets, and a light-emitting diode, allowing for quick recharging via cigarette lighter sockets or accessory power cords, and featuring reverse polarity sensors and voltage testers for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing portable battery chargers are used for jump-starting vehicles, then the function of starting a disabled vehicle is achieved, but the device is cumbersome and inefficient particularly for elderly or disabled individuals
Solution Approach 1:
The battery charger is divided into two separate assemblies: a base assembly containing the first rechargeable battery and a head assembly containing the second rechargeable battery. These assemblies can be used independently or combined, providing flexibility and ease of operation while reducing the complexity of any single unit.
Solution Approach 2:
The battery charger is designed to perform multiple functions: it can charge vehicles independently using either the base assembly or head assembly, or it can combine both assemblies for enhanced charging capability. It also includes an air compressor system for tire inflation and various safety features, making it a versatile emergency tool.
2Loss of time
If existing portable battery chargers are used, then vehicle jump-starting is achieved, but rapid recharging within 10 minutes is not possible
Solution Approach 1:
The battery charger includes preliminary recharging capabilities through multiple charging interfaces (cigarette lighter sockets and accessory power cord receptacles) that can begin charging the rechargeable batteries as soon as they are connected to a power source, reducing waiting time and enabling rapid recharging within 10 minutes.
3Ease of operation
If existing portable battery chargers are used, then jump-starting function is provided, but easy assembly and disassembly without specialized tools is not achieved
Solution Approach 1:
The device is segmented into a base assembly and a head assembly that can be easily connected and disconnected without specialized tools. The modular design allows users to assemble and disassemble the units for storage or transport while maintaining reliable electrical connections through designed interface mechanisms.
4Volume of moving object
If existing portable battery chargers are used, then vehicle starting is achieved, but compact and durable design for carrying and storage is not optimized
Solution Approach 1:
The head assembly can be mounted onto the base assembly, creating a compact integrated unit for storage and transport. When not in use, the removable head assembly nests with the base assembly, reducing overall volume while maintaining durability through secure mounting mechanisms.
