Robot Battery Pack Extension Structure for Low-Height Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs for robots and similar devices pose challenges in easy installation, removal, and replacement, while also increasing the height of the apparatus due to their design.
Innovation Solution
A battery pack design featuring a housing with an upper surface, lower surface, and side surfaces, including a connector and an extension portion that extends outward from the upper surface, allowing for easy mounting and minimizing height increase when installed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery pack is designed with a conventional housing structure, then the battery cells are protected, but the installation height of the apparatus increases
Solution Approach 1:
The extension portion extends in the horizontal direction from the upper surface of the housing, utilizing the horizontal dimension to provide mounting support rather than relying solely on vertical height. This dimensional shift allows the battery pack to be mounted using the extension portion that protrudes horizontally from the housing, thereby reducing the vertical installation height while maintaining structural protection.
2Device complexity
If the battery pack uses a standard mounting design, then the structure is simple, but the installation and removal process is time-consuming
Solution Approach 1:
The extension portion is designed to be automatically engaged with the mounting surface through its horizontal protrusion from the housing upper surface. This self-engaging design allows the battery pack to be quickly installed and removed without requiring complex fastening mechanisms or multiple components, thereby reducing installation time while keeping the overall structure relatively simple.
3Ease of manufacture
If the connector is positioned on the side surface of the housing, then the electrical connection is straightforward, but the center of gravity shifts causing instability
Solution Approach 1:
The extension portion is designed with asymmetric positioning relative to the housing, extending from the upper surface in a specific direction. This asymmetric design allows the connector to be positioned on the extension portion rather than directly on the side surface, enabling electrical connection functionality while distributing weight more favorably to maintain center of gravity stability and prevent apparatus tilt.
