Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging sockets for new energy vehicles face difficulties in quick disassembly and assembly of DC and AC connectors, leading to cumbersome maintenance and high costs due to their fixed nature, which complicates the vehicle assembly process and after-sales maintenance.
Innovation Solution
A charging socket with a detachable mechanism between the current connector and the device fixed to the vehicle body, allowing for easy replacement of damaged connectors and simplifying the assembly process, enabling quick maintenance and mass production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multi-point fastening is used to fix the DC connector and AC connector, then the connection stability is improved, but the disassembly and assembly difficulty increases
Solution Approach 1:
The charging socket is divided into separable components: the current connector (DC or AC connector) and the device fixed to the vehicle body. The detachable mechanism includes a fixing clip with elastic deformation capability that allows the current connector to be snap-fitted into place, providing stable connection while enabling easy one-handed assembly and disassembly without multi-point fastening tools.
2Reliability
If the DC connector and AC connector are fixed permanently, then the connection reliability is improved, but the maintenance time and cost increase
Solution Approach 1:
The fixing clip is designed with elastic deformation capability, allowing it to dynamically adjust during assembly and disassembly. The elastic structure enables the connector to be firmly held during use (maintaining reliability) while allowing easy release when maintenance is needed (reducing maintenance time and cost).
3Reliability
If the entire charging socket is replaced when a connector is damaged, then the system reliability is maintained, but the manufacturing cost and assembly complexity increase
Solution Approach 1:
The charging socket is segmented into replaceable current connector modules and a permanent device fixed to the vehicle body. This allows damaged connectors to be replaced individually rather than replacing the entire assembly, reducing manufacturing costs and simplifying assembly procedures while maintaining system reliability through standardized connection interfaces.
4Manufacturing precision
If multi-point fastening is used, then the manufacturing precision is improved, but the productivity decreases
Solution Approach 1:
The fixing clip is pre-formed with elastic deformation characteristics that automatically provide positioning and locking functions upon insertion. This preliminary preparation of the fastening mechanism eliminates the need for complex multi-point alignment procedures during assembly, maintaining manufacturing precision while dramatically improving productivity through simple snap-fit installation.
