Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is fixedly mounted in the vehicle body through a fixed power-on socket, then the connection stability is improved, but the adaptability and ease of operation deteriorate because the vehicle must be driven to a charging location when the battery charge is low
Solution Approach 1:
The battery system is segmented into a removable battery pack and a vehicle body interface. The battery pack can be detached and replaced independently, allowing the battery to be charged separately while the vehicle remains operational. This segmentation resolves the contradiction by maintaining stable electrical connections during use while enabling flexible charging operations.
Solution Approach 2:
The invention implements a battery replacement mechanism where depleted batteries are discarded (removed from the vehicle) and recovered (recharged externally). The vehicle can quickly swap to a fresh battery pack, eliminating the need to drive to charging locations during operation. This approach maintains connection stability during operation while providing charging flexibility through rapid battery exchange.
2Ease of manufacture
If the battery structure uses a simple mounting method, then the ease of manufacture is improved, but the fixation strength and connection stability deteriorate
Solution Approach 1:
The battery pack employs a nested structure where the battery case contains internal fixing components, and the vehicle body interface has corresponding receiving structures. The fixing pieces are nested within the battery case assembly, and the guide rails are integrated into the vehicle body. This nested design achieves strong fixation through multiple nested components while maintaining ease of manufacture through modular assembly.
Solution Approach 2:
The invention merges multiple functions into integrated components: the battery case combines structural housing with internal fixing mechanisms, the handle integrates with locking pieces, and the vehicle body interface combines guide rails with power connection sockets. This merging achieves strong fixation strength through combined structural elements while maintaining manufacturing simplicity through integrated design.
3Strength
If the battery structure uses a complex locking mechanism, then the fixation strength is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism employs self-service features where the elastic deformable piece automatically engages with the locking groove when the battery pack is inserted, and the handle with locking piece automatically secures the battery in position. The guide rails automatically guide the battery into the correct position during insertion. These self-service characteristics achieve strong fixation strength while minimizing device complexity by eliminating the need for complex manual locking operations or additional control systems.

AI summary
The present disclosure relates to a battery structure and a carrier vehicle. The battery structure includes a battery main body, a plug component, and a handle. The handle is detachably connected to the top or the side of the battery main body. The plug component includes at least one plug end. The plug end can be plugged into the battery main body and the plug component is powered on when plugged into the battery. The handle is provided with a locking piece. When the handle is connected to the top of the battery main body, the locking piece is vertically docked for locking. When the handle is connected to the side of the battery main body, the locking piece is transversely docked for locking.
