Snap Ring Pliers With Rotating Clamps For Secure Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snap ring pliers operate unsafely due to the sliding motion of clamp feet relative to the snap ring, which can lead to unstable fixing and removal processes.
Innovation Solution
The snap ring pliers feature a handle, first and second clamps with integrated arcuate sections and straight sections, and an adjustment structure with threaded posts and a sleeve, allowing the clamps to rotate oppositely along a connection column, maintaining a consistent angle between clamp feet and snap ring apertures, ensuring secure engagement without sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clamp feet slide relative to the snap ring during rotation, then the operation is easier to perform, but the fixing reliability deteriorates and operation safety is compromised
Solution Approach 1:
The clamp feet are designed with dynamic adaptability through arcuate contact surfaces that automatically adjust to maintain optimal contact angles with the snap ring during rotation. This dynamic geometry allows the clamp feet to rotate smoothly while continuously maintaining secure engagement, eliminating the sliding problem while preserving ease of operation.
Solution Approach 2:
The contact angle between the clamp feet and snap ring is changed from a fixed parameter to a dynamically optimized parameter. The arcuate geometry of the clamp feet creates a varying contact angle during rotation that maintains maximum friction and engagement, ensuring reliable fixing while allowing smooth rotational operation.
2Productivity
If the clamp feet are forced to rotate along the connection column, then the snap ring can be fixed or removed, but the clamp feet slide and detach from the snap ring causing operation unsafe
Solution Approach 1:
The clamp feet incorporate arcuate contact surfaces with carefully designed curvature radii that match the snap ring geometry. This curved geometry ensures that during rotation along the connection column, the clamp feet maintain continuous point contact with the snap ring apertures, preventing detachment while enabling efficient fixing and removal operations.
Solution Approach 2:
The arcuate geometry of the clamp feet is designed in advance to counteract the detaching force that occurs during rotation. By pre-configuring the contact surfaces with optimal curvature, the design prevents the harmful sliding and detachment effect before it can occur, ensuring safe operation throughout the entire rotation process.

Function Achieved in This Case
This design ensures secure fixation and removal of snap rings by maintaining a consistent angle between clamp feet and snap ring apertures, preventing sliding and enhancing operational safety.
Implementation Method 1
The threaded rod 146 has a first screwing section 1462 and a second screwing section 1416... When the threaded rod 146 is rotated, the first screwing section 1462 forces the first clamper 12 to rotate along the connection column 15, and the second screwing section 1464 urges the second clamper 13 to rotate along the connection column 15
Implementation Method 2
A top of each of the first clamper 12 and the second clamper 13 is rotatably connected with a connection column 15 of the handle... such that the first clamper 12 and the second clamper 13 are rotated reciprocately along the connection column 15
