Quick Release Mechanism for Hand and Pole Sanders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand sanders and pole sanders require users to switch between tools, necessitating a quick release mechanism to efficiently transition between hand sander and pole sander modes, as current technologies lack a seamless attachment and detachment solution.
Innovation Solution
A quick release mechanism comprising a frame connecting means and a base connecting means, utilizing a push pad, catch, catch flange, lip, and slot flange for easy attachment and detachment, with a latch and hinge member to resiliently bias the catch against the catch flange, allowing for rapid switching between hand sander and pole sander configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional attachment mechanism is used to connect hand sander and pole sander, then the connection is secure and reliable, but the attachment and detachment process is time-consuming and complex
Solution Approach 1:
The attachment mechanism is divided into separate components: a frame connecting means with a catch on the frame, and a base connecting means with a catch flange on the base. The catch and catch flange are positioned to cooperate when the frame is urged onto the base, enabling quick engagement without complex multi-step procedures.
Solution Approach 2:
The catch is pre-positioned on the frame and the catch flange is pre-positioned on the base. When the frame is urged onto the base, the catch automatically engages with the catch flange in a predetermined manner, eliminating the need for complex alignment or manual positioning operations.
2Productivity
If a quick release mechanism is implemented to enable rapid switching between hand sander and pole sander modes, then the attachment and detachment speed is improved, but the mechanism complexity increases
Solution Approach 1:
The frame connecting means and base connecting means are merged into a single integrated quick release mechanism. The catch on the frame and catch flange on the base work together as a unified system that enables both secure attachment and rapid detachment through a single urging motion, avoiding the need for multiple separate mechanisms.
Solution Approach 2:
The quick release mechanism is designed to be self-actuating. When the frame is urged onto the base, the catch automatically engages with the catch flange without requiring external actuation or complex control systems. The mechanism serves itself by using the urging motion to automatically complete the attachment action.
3Device complexity
If a simple attachment mechanism is used for quick switching between hand sander and pole sander, then the mechanism complexity is reduced, but the connection security and reliability deteriorate
Solution Approach 1:
The catch and catch flange are designed with curved or angled surfaces that guide the engagement process. The catch on the frame and catch flange on the base feature geometric shapes that naturally align and secure the connection, providing reliable engagement through simple geometric interlocking rather than complex mechanical features.
