Deformable Base for Snap Ring Installation on Impact Wrench Anvils
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installing snap rings onto the anvils of impact wrenches is notoriously difficult and time-consuming due to their rugged and resilient characteristics, as well as limited grasping locations.
Innovation Solution
A method involving a deformable base with an annular seat or counterbore that expands to facilitate the snap ring's movement from a closed to an open position, allowing quick installation of the snap ring over the anvil and onto an O-ring in an annular groove, typically within one second.

Engineering Contradiction Analysis
1Productivity
If traditional manual installation methods are used, then the snap ring can be installed, but the process is time-consuming and difficult due to the rugged and resilient characteristics of snap rings
Solution Approach 1:
The snap ring is pre-seated in the annular seat of the base before the anvil is inserted. This preliminary positioning ensures the snap ring is correctly oriented and ready for installation, eliminating the need for manual manipulation during the installation process and significantly reducing installation time and difficulty.
Solution Approach 2:
The base with the annular seat acts as an intermediary device between the installer and the snap ring. The annular seat provides a controlled environment for the snap ring, allowing it to be easily manipulated and positioned before being transferred to the anvil, thus simplifying the installation process.
2Stability of the object's composition
If the snap ring is held in a rigid fixed-position seat, then the snap ring position is stable, but the snap ring cannot be deformed to expand for installation over the anvil
Solution Approach 1:
The annular seat is designed with deformable characteristics that allow it to dynamically adapt to the installation process. When the anvil is inserted, the annular seat deforms to accommodate the expansion of the snap ring, providing both initial stability for positioning and subsequent adaptability for deformation during installation.
Solution Approach 2:
The physical state of the annular seat is changed from a rigid fixed structure to a deformable structure that can change its dimensional parameters. This allows the seat to maintain the snap ring in a closed position during seating, then deform to allow expansion when the anvil is inserted, accommodating both stability and adaptability requirements.

AI summary
A method of installing a snap ring, having opposed inner and outer diameters, onto an O-ring located in an annular groove of an anvil of an impact wrench includes providing a deformable base formed with an annular seat, seating the snap ring in into the annular seat, and applying the anvil of the impact wrench through the snap ring and into the deformable base applying the snap ring over the anvil and onto the O-ring located in the groove, wherein the anvil interacts with the snap ring in response to applying the anvil into and through the snap ring enlarging inner and outer diameters of the snap ring deforming the annular seat of the base allowing the snap ring to be received over the anvil and onto the O-ring located in the annular groove.
