Removable Tongue Adapter for Reciprocating Drivers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick-change systems for power tools with reciprocating drivers often require tools like screwdrivers or wrenches to change attachments, leading to inefficiency and potential damage to adapters, necessitating a solution for tool-less attachment and easy replacement of damaged components.
Innovation Solution
A system featuring a removable and replaceable mounting member with a quick-change socket assembly that allows for tool-less engagement and disengagement of attachments using a push-on force, incorporating a snap ring mechanism and balls for secure engagement, enabling easy replacement of damaged parts without full adapter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamp-type mounting arrangement is used to secure attachments to the power unit, then the attachment can be securely retained, but a tool such as a screwdriver or wrench is required to remove and replace the attachment
Solution Approach 1:
The mounting system is divided into two functional segments: a fixed clamp-type mounting arrangement on the power unit that provides secure retention, and a separate removable adapter that interfaces with both the power unit and the attachment. This segmentation allows the attachment to be securely held while enabling tool-less removal through the adapter mechanism.
Solution Approach 2:
An adapter serves as an intermediary component between the clamp-type mounting arrangement and the attachment. The adapter includes a mounting portion that interfaces with the power unit's clamp mechanism and a tool-less release mechanism that allows the attachment to be quickly removed and replaced without requiring tools.
2Ease of operation
If an adapter remains in place on the power unit to enable quick-change attachments, then tool-less engagement is achieved, but the end of the adapter that interfaces with the power unit may become damaged or unusable
Solution Approach 1:
The adapter is segmented into a permanent mounting portion that remains on the power unit and a removable interface portion that connects to attachments. This allows the durable mounting portion to stay fixed while the removable portion can be replaced if damaged, separating the retention function from the interface function.
Solution Approach 2:
The adapter design allows the interface portion to be discarded (removed and replaced) when damaged, while the permanent mounting portion remains on the power unit for continued use. This enables recovery of the functional mounting system without replacing the entire adapter assembly.
3Reliability
If the entire adapter is replaced when the mounting portion becomes damaged, then a functional system is restored, but unnecessary parts are discarded and cost increases
Solution Approach 1:
The adapter is designed as segmented components: a permanent mounting portion that remains on the power unit and replaceable interface portions. This allows only the damaged interface portion to be replaced while retaining the usable mounting portion, reducing material loss and cost.
Solution Approach 2:
When damage occurs to the adapter, only the necessary portion is discarded and replaced, while the remaining functional portions are recovered and retained on the power unit. This minimizes waste and reduces the cost of restoring full functionality to the mounting system.
