Flexible Battery Socket Layout for Balanced Electric Grinders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-powered electric grinding tools face challenges due to the weight and balance issues caused by large-capacity batteries, leading to difficulty in operation and potential for unstable grinding quality and user fatigue.
Innovation Solution
A power supply structure for electric grinding tools that includes a power management module, a power connecting wire, and a battery socket that can be positioned arbitrarily, allowing the replaceable battery to be placed anywhere along the wire, thereby distributing the weight and reducing the burden on the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a large-capacity battery is used to power the grinder, then the power supply capability is improved, but the weight of the tool machine increases
Solution Approach 1:
The battery system is segmented into a fixed battery pack integrated into the tool machine and a separate replaceable battery that can be positioned independently via a battery holder and connecting wire, allowing the power capacity to be divided and distributed flexibly
Solution Approach 2:
The battery positioning system transitions from a fixed one-dimensional slot to a flexible three-dimensional arrangement using a connecting wire, allowing the battery to be positioned at multiple locations along the wire to optimize weight distribution and balance
2Adaptability or versatility
If a battery slot and replaceable battery are added to the grinder, then the battery-powered operation is enabled, but the weight distribution becomes unbalanced
Solution Approach 1:
The battery positioning system is made dynamic and adjustable, allowing the battery to be moved to different positions along the connecting wire to optimize weight balance according to specific operational requirements, rather than being fixed in a single location
Solution Approach 2:
A battery holder and connecting wire are introduced as intermediary components between the tool machine and the replaceable battery, enabling flexible positioning and weight distribution while maintaining electrical connection
3Device complexity
If the battery slot is mounted on the tail end of the main body, then the structure is simplified, but the grinding position control becomes difficult
Solution Approach 1:
The power supply system is segmented into a fixed component (battery slot on main body) and a movable component (battery on connecting wire), allowing the structural simplicity to be maintained while gaining operational flexibility through the movable battery position
