Solution Overview
Problem
Existing power tool systems lack a unified platform that allows for versatile and efficient power delivery across different tools, with limited standardization in battery packs and control systems, leading to inefficiencies and increased complexity.
Innovation Solution
A power tool system featuring a removable battery pack and a common base housing with a proportional power delivery system and actuator, allowing multiple tools to share a common battery pack and control components, such as circuit boards and controllers, which provide 80 W to 120 W pulse-width-modulation power delivery, enabling user control and versatility across various tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple power tools use separate battery packs and control systems, then each tool can be optimized independently, but the overall system complexity increases and standardization is limited
Solution Approach 1:
The patent implements a universal base housing design that can accommodate multiple different tool portions (rotary tool, soldering iron, lamp, fan, glue gun), allowing a single standardized platform to perform multiple functions across different tool types while reducing overall system complexity through component sharing
2Ease of manufacture
If each tool has its own dedicated power delivery system, then power control is precise for each tool, but the system lacks standardization and efficiency
Solution Approach 1:
The patent merges the power delivery control functionality into a centralized controller housed in the common base housing, which manages power distribution to multiple different tool portions through a standardized interface, achieving both standardization and efficient power control
3Productivity
If a common base housing is used for multiple tools, then component sharing and efficiency improve, but the design must accommodate diverse tool requirements
Solution Approach 1:
The patent employs a dynamic configuration where the base housing maintains a consistent standardized interface for power and control, while allowing different tool portions to be selectively attached and detached, enabling the system to adapt to various tool requirements while maintaining efficient standardized power delivery

AI summary
A power tool system includes a removable battery pack a first tool and a second tool. The first tool includes a first base housing that is selectively engageable with the removable battery pack and a first tool portion connected to the first base housing by a first connecting section. The second tool includes a second base housing that is selectively engageable with the removable battery pack and a second tool portion connected to the second base housing by a second connecting section. The second tool base housing houses a second controller that provides a proportional power delivery system for the second tool and second tool base housing also includes a second actuator for providing user control of the second tool.
