Power Tool Accessory Brace for Quick-Release Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tool accessory systems require the use of secondary tools for removal and reattachment of accessories, which is time-consuming and inefficient.
Innovation Solution
A power tool accessory system with a brace that includes a clamp assembly and arm assembly, allowing for tool-free removal and reattachment of accessories by utilizing a quick release connector and adjustable length mechanisms, enabling the accessory housing to be removably and rigidly coupled to the power tool housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional power tool accessory system uses fixed coupling mechanisms, then the accessory is securely attached to the power tool, but the removal and reattachment process requires secondary tools and is time-consuming
Solution Approach 1:
The brace is divided into separable components: a clamp assembly that remains attached to the power tool and an arm assembly that can be quickly detached. This segmentation allows the arm assembly to be removed without requiring removal of the entire brace or use of secondary tools, while the clamp assembly maintains secure attachment to the power tool housing.
Solution Approach 2:
The coupling mechanism transitions from a fixed, permanent attachment to a dynamic, selectively removable connection. The arm assembly incorporates a quick-release feature that enables it to be easily detached from the clamp assembly when needed, while maintaining rigid coupling during operation. This dynamic capability allows rapid switching between different arm assemblies without tool intervention.
2Reliability
If the brace uses a rigid fixed connection, then structural stability is maintained, but the ability to quickly remove and replace accessories is reduced
Solution Approach 1:
The brace system is segmented into a stationary clamp assembly that provides stable mounting to the power tool and a movable arm assembly that can be independently removed. This segmentation maintains structural integrity through the clamp assembly while enabling easy interchangeability of the arm assembly through its detachable design.
Solution Approach 2:
The clamp assembly serves as an intermediary component that remains permanently attached to the power tool housing, providing a stable mounting point. The arm assembly connects to this intermediary rather than directly to the power tool, allowing the arm to be easily detached and replaced while the clamp maintains structural stability.
3Adaptability or versatility
If the entire brace is removed for accessory changes, then complete reconfiguration is possible, but the process becomes more complex and time-consuming
Solution Approach 1:
The brace is segmented into two functional parts: a clamp assembly that provides stable mounting to the power tool and an arm assembly that can be independently removed. This allows users to change accessories by detaching only the arm assembly, maintaining adaptability while significantly reducing the complexity of the reconfiguration process compared to removing the entire brace.

AI summary
A power tool accessory system for a power tool includes a power tool accessory with a housing, an input shaft rotatably driven by a power tool, and a working tool driven to perform an operation upon rotation of the input shaft. The system also includes a brace configured to removably couple the housing to the power tool while the input shaft rotates. The brace includes a clamp assembly configured to be fixedly coupled to a base of the power tool handle, and an arm assembly with a first end portion configured to be coupled to the housing and a second end portion configured to be coupled to the clamp assembly. The second end portion is removable from the clamp assembly while the clamp assembly remains fixedly coupled to the power tool to enable removal of the power tool accessory from the power tool.
