Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic battery swapping devices for AGV vehicles lack a position adjustment mechanism, leading to uneven stress on the pick-and-place mechanism and low battery replacement efficiency.
Innovation Solution
An automatic battery swapping device with a thrust assembly, sensor, and adjustment assembly that detects the position of the attraction member relative to the battery and adjusts its position to ensure alignment with the battery's central area, using an electromagnetic chuck for attraction and release, and a guide groove for smooth battery transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an automatic battery swapping device is used without a position adjustment mechanism, then automation is improved, but the contact position deviation causes uneven stress and reduces swapping efficiency
Solution Approach 1:
The patent introduces a position adjustment assembly that enables the pick-and-place mechanism to dynamically adjust its position relative to the battery. This dynamic adjustment capability allows the system to maintain optimal contact position despite variations in battery placement, thereby resolving the contradiction between automation and swapping efficiency by enabling the automated system to adapt to position deviations.
Solution Approach 2:
The patent employs sensors to detect the actual position of the battery and provides feedback to the control system. Based on this feedback, the position adjustment assembly modifies the contact position of the pick-and-place mechanism to compensate for deviations. This feedback loop ensures that the automated battery swapping process maintains high efficiency by continuously correcting position errors.
2Extent of automation
If the pick-and-place mechanism contacts the battery at a deviated position, then automation is maintained, but uneven stress affects swapping efficiency
Solution Approach 1:
The position adjustment assembly enables the pick-and-place mechanism to dynamically compensate for position deviations by adjusting its contact point on the battery. This dynamic adjustment ensures that the force is applied at the correct position, maintaining uniform stress distribution and preventing reliability issues associated with uneven stress, while preserving the automated handling process.
3Manufacturing precision
If manual battery replacement is used, then position accuracy can be maintained, but labor costs increase and automation decreases
Solution Approach 1:
The patent implements a system where the pick-and-place mechanism automatically detects its own position deviation relative to the battery and self-corrects using the position adjustment assembly. This self-service capability eliminates the need for manual intervention to ensure position accuracy, thereby maintaining high contact position accuracy while preserving full automation of the battery replacement process.
Solution Approach 2:
The sensor-based feedback system continuously monitors the position between the pick-and-place mechanism and the battery, enabling automatic correction of position deviations. This feedback loop replaces manual position verification and adjustment, maintaining manufacturing precision while achieving complete automation of the battery replacement process.
