Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a built-in battery pack is used in the self-moving device, then the device can operate autonomously, but the battery pack cannot be manually detached and requires tools for mounting or detaching
Solution Approach 1:
The battery pack is designed as a separate, detachable module from the self-moving device body. The battery pack includes its own housing, electrical connection terminals, and mounting features that allow it to be independently removed and attached without tools, resolving the contradiction between autonomous operation and ease of detachment.
Solution Approach 2:
The battery pack is extracted as a standalone component with all necessary functional elements (power cells, connection terminals, mounting structure) integrated into it. This allows the battery pack to be removed from the device body and used separately in other electric tools, eliminating the need for tool-based attachment while maintaining operational autonomy.
2Productivity
If a detachable battery pack is used in electric tools, then the battery pack can be replaced when power is depleted, but work must be stopped to replace batteries and charge them
Solution Approach 1:
The battery pack is designed with universal compatibility to power multiple different electric tools and the self-moving device. The standardized electrical connections and mounting interface allow a single battery pack to be used across various devices, enabling users to maintain multiple charged battery packs and quickly swap them between different tools without stopping work or returning to charge them.
Solution Approach 2:
Multiple battery packs can be charged in advance before needed. When one battery pack is depleted, pre-charged replacement battery packs are already available for immediate swapping, eliminating the need to stop work and wait for charging. The universal design allows these pre-charged batteries to be used across multiple devices.
3Adaptability or versatility
If the energy module is selectively configured to supply power to the self-moving device or another electric tool, then versatility is improved, but the device structure becomes more complex
Solution Approach 1:
The battery pack incorporates universal electrical connection terminals and standardized mounting features that enable it to interface with multiple different electric tools and the self-moving device. This multi-functional design achieves versatility without significantly increasing the battery pack's internal structural complexity, as the interface elements are standardized rather than customized for each device.
4Reliability
If a protective cover is added to block the inlet of the accommodating cavity, then water-proof performance is improved, but the device structure becomes more complex
Solution Approach 1:
The protective cover is designed as a separate, removable component that attaches to the battery pack housing to seal the inlet of the accommodating cavity. This segmented approach provides water-proof protection without integrating complex sealing mechanisms into the main battery structure, maintaining simplicity while improving reliability.
Solution Approach 2:
The protective cover likely employs a simple hinged or snap-fit design with basic sealing features, using flexible mounting rather than rigid complex structures. This allows the cover to effectively block water ingress while maintaining ease of attachment and removal, balancing protection with structural simplicity.

AI summary
An automatic working system includes a self-moving device moving and working inside a defined working area and an energy module supplying power to the self-moving device. The self-moving device includes a body, a movement module, a task execution module, and a control module. The energy module is selectively configured to supply power to the self-moving device or another electric tool different from the self-moving device. The self-moving device includes an accommodating cavity provided with an inlet and configured to accommodate the energy module and a protective cover configured to operably block the inlet. The self-moving device further includes a drainage system configured to drain water to prevent water from entering the accommodating cavity.
