Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-powered electric grinding tools face challenges due to the need for large, heavy batteries to supply continuous power, leading to increased weight and difficulty in handling, which affects operation stability and user comfort.
Innovation Solution
A power supply structure with a detachable battery socket and power connecting wire that allows the battery to be positioned anywhere, reducing the counterweight and enabling easier handling by distributing the battery's weight more evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a large-capacity battery is used to supply continuous power for grinding operations, then the power requirement is met, but the weight of the tool machine increases significantly
Solution Approach 1:
The power supply system is segmented into two parts: a small-capacity battery integrated into the tool machine for basic power needs, and a separate external battery pack that can be detached and repositioned. This segmentation allows the main body to remain lightweight while still providing access to large total power capacity when needed.
Solution Approach 2:
The battery is extracted from the integrated design and separated into a detachable external pack connected via power connecting wire. This extraction removes the heavy battery mass from the tool machine body, allowing users to operate with reduced weight while maintaining the option to connect external power when continuous operation is required.
2Duration of action of moving object
If a heavy battery is attached to the tool machine, then continuous power is available, but the user experiences difficulty in handling and control
Solution Approach 1:
The battery configuration is made dynamic and adaptable rather than fixed. Users can switch between integrated battery mode (lightweight, easy handling) and external battery pack mode (extended duration) based on operational needs. The detachable design allows the system to adapt its weight and power capacity dynamically.
Solution Approach 2:
The power supply capacity is made variable depending on the working condition. The integrated battery provides sufficient power for short-duration tasks, while the external battery pack extends operational duration for continuous grinding tasks. Each configuration optimizes the balance between power availability and handling ease for specific local conditions.
3Device complexity
If the battery socket is fixed at one position, then the structure is simple, but the weight distribution is unbalanced affecting grinding quality
Solution Approach 1:
The battery positioning problem is solved by adding spatial flexibility through the power connecting wire, which allows the battery to be positioned in multiple locations (on the tool machine body or externally). This dimensional freedom enables optimal weight balance to be achieved without complicating the fundamental socket structure.
Solution Approach 2:
The power connecting wire acts as an intermediary element that decouples the battery from fixed positional constraints. This mediator allows the battery to be positioned at optimal locations for weight balance while maintaining electrical connection, thus improving grinding quality without requiring complex integrated battery mounting structures.
