Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connections in charging gun heads and stands suffer from misalignment due to manufacturing errors, leading to increased contact resistance, excessive temperature rise, and potential safety hazards like fire, exacerbated by 'failure infection' when terminals are forcibly plugged.
Innovation Solution
A self-adjusting centering terminal mounting structure with a conductive terminal and terminal clamping seat featuring a clamping groove and mounting hole with adjustable clearances, allowing for automatic centering adjustment to accommodate different charging stands or gun heads, reducing the spread of 'failure infection'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a terminal is mounted away from the centerline of a vehicle to provide a wider field of view, then the field of view is improved, but image distortion increases
Solution Approach 1:
The mounting structure allows the terminal to dynamically adjust its position along the x-axis (horizontal direction) while maintaining a fixed y-axis height. This dynamic positioning capability enables the terminal to be mounted away from the centerline for wider field of view, while still allowing for precise angular adjustment to minimize image distortion through the adjustable mounting angle mechanism.
Solution Approach 2:
The system changes the mounting parameters by allowing adjustable mounting angles (both horizontal and vertical) and variable positions along the x-axis. By optimizing these parameters, the terminal can be positioned away from the centerline to expand field of view while adjusting the mounting angle to compensate for and reduce image distortion.
2Area of moving object
If a terminal is mounted away from the centerline of a vehicle, then the field of view is improved, but the terminal becomes more susceptible to damage from side impacts
Solution Approach 1:
The adjustable mounting structure provides dynamic positioning capability along the x-axis, allowing the terminal to be mounted away from the centerline for improved field of view. The adjustable angle mechanism enables precise orientation to optimize both viewing coverage and structural protection, balancing field of view expansion with impact resistance.
Solution Approach 2:
The mounting structure provides localized adjustment capability specifically in the horizontal direction (x-axis) while maintaining fixed vertical positioning. This localized flexibility allows the terminal to be positioned optimally for field of view without compromising overall structural integrity and impact resistance.
3Device complexity
If conventional mounting methods are used, then the structure is simple, but the terminal cannot be precisely adjusted to optimal positions
Solution Approach 1:
The mounting structure incorporates adjustable components that enable dynamic positioning of the terminal along the x-axis and angular adjustment in both horizontal and vertical directions. This dynamic capability provides precise adjustability to optimal positions while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The mounting structure is divided into separate adjustable components: a horizontal adjustment mechanism for x-axis positioning and an angular adjustment mechanism for orientation. This segmentation allows independent adjustment of each parameter while keeping the overall structure simple and manageable.

AI summary
The present disclosure provides a self-adjusting and centering terminal mounting structure, including a conductive terminal (1) and a terminal clamping seat (2). The conductive terminal (1) includes a fixed section (12). The fixed section (12) is externally provided with a clamping groove (14). The terminal clamping seat (2) is internally provided with a mounting hole (21). The clamping groove (14) of the conductive terminal (1) is disposed in the mounting hole (21), and a mounting clearance (3) is formed between the clamping groove (14) and the mounting hole (21). The self-adjusting centering terminal mounting structure can realize automatic centering adjustment between terminals of a plugged structure, thereby not only adapting to plugging and unplugging of different charging stands or charging gun heads, but also avoiding the spread of `failure infection'.
