Suction Device with Integrated Charging for Hand-Held Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices for hand-held power tools require separate chargers, which are inconvenient, especially in remote or construction site settings, and can be easily forgotten.
Innovation Solution
Integration of a charging device within the suction device that allows for on-site charging of the hand-held power tool's energy storage module, eliminating the need for a separate charger and enabling wireless communication for controlling the suction motor and charging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate charger is used for the hand-held power tool, then the energy storage module can be charged, but the charging process becomes inconvenient and the charger can be easily forgotten
Solution Approach 1:
The patent merges the charging device with the suction device by integrating a holder and charging contacts into the suction device housing. This allows the energy storage module to be charged conveniently at the suction device location without requiring a separate charger, thus improving ease of operation while reducing the number of separate components.
2Ease of operation
If the charging device is integrated into the suction device, then charging convenience is improved, but the suction device structure becomes more complex
Solution Approach 1:
The suction device is designed with multi-functionality by incorporating both suction functionality and charging functionality into a single device. The holder and charging contacts are integrated into the existing suction device structure, allowing it to serve dual purposes without significantly increasing overall complexity.
3Adaptability or versatility
If the energy storage module is detachable from the hand-held power tool, then module exchange is enabled, but the charging connection requires additional alignment precision
Solution Approach 1:
The holder acts as an intermediary component between the energy storage module and the charging contacts. It provides a stable mounting position and guides the module into proper alignment with the charging contacts, thereby enabling easy module exchange while maintaining accurate alignment without requiring high manufacturing precision.
