Solution Overview
Problem
The complexity of assembling a large-capacity battery system to a vehicle body increases the risk of connection failures due to manual operation errors, as existing docking structures lack precision and reliability.
Innovation Solution
A docking structure with a connector system featuring a guide pin and aperture design, where the guide pin tapers and the aperture has an inclined surface, combined with an elastic member and bracket assembly, ensures accurate alignment and secure coupling of the battery to the vehicle body, eliminating misconnection risks and accommodating dimensional tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual operation for connecting a separate connector is performed after physical coupling, then the battery can be assembled to the vehicle body, but connection failure may occur due to negligence or error of operator
Solution Approach 1:
The patent merges the physical coupling process with the electrical connector connection into a single integrated operation. The guide pin and guide aperture structure automatically aligns and connects the connector during the battery assembly process, eliminating the need for separate manual connector connection steps and preventing operator errors.
Solution Approach 2:
The docking structure enables self-alignment and self-connection through the guide pin and guide aperture mechanism. When the battery is positioned on the vehicle body, the guide pin automatically guides the connector into proper alignment with the aperture, allowing the system to self-correct and complete the connection without manual intervention.
2Quantity of substance
If the size and capacity of battery system are increased, then more electric energy can be stored, but the assembly process becomes more complex
Solution Approach 1:
The patent combines multiple assembly functions (positioning, alignment, and electrical connection) into a single integrated docking structure. This simplification is particularly beneficial for large-capacity battery systems, as it reduces the complexity of assembling bigger, heavier batteries while maintaining precise alignment and secure electrical connections.
