Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging cables for electric vehicles, particularly those used for large vehicles like aircraft, are heavy and inconvenient to move, with no existing solution for easy handling.
Innovation Solution
A mobile charging apparatus with a housing, lid, wheels, lights, and speakers, capable of connecting to a 240 V AC wall outlet and outputting 600 V DC for high-power charging, featuring a compartment for storing cables and a power switch for safe and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If heavy charging cables are used for high-power charging of large electric vehicles, then charging power capability is improved, but mobility and ease of operation deteriorate
Solution Approach 1:
The charging system is divided into two separate units: a stationary high-power charging unit that remains connected to the power source, and a mobile cable storage unit with wheels that can be easily moved. This segmentation allows the heavy cable to be stored in the mobile unit while the charging unit provides high power capability, resolving the contradiction between power capability and mobility.
Solution Approach 2:
The mobile cable storage unit acts as an intermediary between the stationary charging unit and the electric vehicle. It houses the heavy charging cable and provides a handle for easy movement, mediating between the fixed high-power source and the vehicle needing charging, thus enabling both high power delivery and operational mobility.
2Productivity
If heavy charging cables are used for high-power charging, then charging efficiency is improved, but handling convenience deteriorates
Solution Approach 1:
By separating the charging function into a stationary unit (providing high-power output for efficiency) and a mobile storage unit (providing easy handling through wheels and handle), the system achieves both high charging efficiency and convenient handling without compromise.
Solution Approach 2:
The system introduces dynamic mobility to the cable management through wheels and a handle, allowing the cable storage unit to be easily repositioned as needed. This dynamic element resolves the static contradiction between having a fixed heavy cable setup for efficiency versus needing to move it for convenience.
3Ease of operation
If a mobile charging apparatus with wheels is used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The complexity of the mobile charging system is segmented into simple, discrete components: a housing, a lid, wheels for mobility, and a handle. Each component performs a single function, making the overall system easier to understand and operate despite adding mobility features, thus managing device complexity while improving ease of operation.
