Working Machine Power Receptacle for Mixed Battery Pack Shapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working machines require long work times and are limited by the use of battery packs with specific housing shapes, preventing the use of alternative power supplies with different housing configurations.
Innovation Solution
A working machine designed to accommodate both a first power supply with a backpack battery and a second power supply, each with distinct housing shapes, through a power supply receptacle and connector coupler system that allows for secure attachment and detachment, ensuring compatibility and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a power supply with a larger rated capacity is used to extend operational time, then the working machine can operate for longer periods, but the housing shape of the power supply changes, making it incompatible with the original battery pack receptacle
Solution Approach 1:
The patent designs a universal power supply receptacle that can accommodate multiple types of power supplies with different housing shapes (e.g., cylindrical battery packs and rectangular power supplies). The receptacle includes a base member with a power supply receiving space and multiple engagement parts that can interact with different engagement surfaces of various power supply types, enabling one receptacle to serve multiple functions and accept diverse power sources.
2Adaptability or versatility
If the power supply receptacle is designed to accommodate multiple power supply shapes, then versatility is improved, but the structural complexity of the receptacle increases
Solution Approach 1:
The power supply receptacle is segmented into multiple functional components: a base member with a receiving space, multiple engagement parts (first and second engagement parts) with different engagement surfaces, and a cover member. Each engagement part has specifically designed engagement surfaces that can interact with different types of power supplies. This segmentation allows the receptacle to handle multiple power supply shapes through modular engagement mechanisms rather than a monolithic complex structure.

AI summary
A working machine may be configured to operate with electric power supplied from a first power supply or a second power supply and configured to be used in a state of being in contact with a ground. Each of the first power supply and the second power supply may include a battery cell; a housing configured to house the battery cell; a power cable extending from the housing and configured to discharge electric power; and a connector disposed at an end of the power cable. The housing of the first power supply and the housing of the second power supply may have different shapes from each other. The working machine may include a power supply receptacle to which either the first power supply or the second power supply is configured to be detachably attached; and a connector coupler configured to be coupled with the connector.
