Oscillating Tool Accessory Clamping Flange Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oscillating power tools require manual adjustment and fastening mechanisms for securing and releasing accessories, which can be cumbersome and inefficient.
Innovation Solution
An oscillating power tool with a pivotable clamping flange and actuator mechanism that allows for tool-free attachment and detachment of accessories by moving the accessory shaft between clamping and release positions, utilizing a biasing system to secure the accessory between the clamping flange and base flange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fastening mechanisms (screws, manual adjustment) are used to secure accessories, then the accessory can be securely attached, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The clamping flange is designed to be dynamically movable between a clamping position (where it secures the accessory) and a release position (where it allows accessory removal). This dynamic mechanism eliminates the need for manual fastening operations, allowing users to simply move the flange to attach or detach accessories quickly without time-consuming screw operations
Solution Approach 2:
The biasing member automatically applies clamping force to secure the accessory between the clamping flange and base flange without requiring manual intervention. The system serves itself by using spring force to maintain the clamping action, eliminating the need for users to manually tighten or adjust fastening mechanisms
2Device complexity
If manual fastening mechanisms are used, then the accessory can be securely held, but the device complexity increases due to additional fastening components
Solution Approach 1:
The invention extracts and eliminates the traditional screw or manual fastening components from the accessory attachment system. By removing these complex fastening elements and replacing them with a simple movable clamping flange mechanism, the overall device complexity is reduced while simultaneously improving ease of operation
Solution Approach 2:
The movable clamping flange serves multiple functions: it provides the clamping action to secure the accessory, it acts as the release mechanism when moved to the release position, and it works in conjunction with the biasing member to maintain secure attachment. This multi-functional design reduces the need for separate fastening components, simplifying the overall structure
