Snap Ring Pliers Tongue Tip for Impact Wrench Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing tools lack a specialized device for efficiently installing and removing snap rings from impact wrenches, making the process difficult and time-consuming due to the absence of a dedicated tool for this purpose.
Innovation Solution
The design of snap ring pliers with pivotally coupled sections, spring-biased jaws, and snap ring engaging surfaces allows for easy installation and removal of snap rings by forming a tongue to fit into the snap ring gap and applying a forcible impulse to open the jaws, facilitating the retention and release of snap rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a specialized tool is designed for installing and removing snap rings, then the ease of operation and time required for maintenance are improved, but the device complexity increases
Solution Approach 1:
The pliers are divided into two separate sections (first section with first jaw portion and second section with second jaw portion) that can pivot relative to each other. This segmentation allows each jaw portion to be independently positioned and shaped to engage with specific parts of the snap ring, improving operational ease while keeping each individual section relatively simple in structure.
Solution Approach 2:
The pivot connection between the two sections enables dynamic movement between different jaw configurations. The jaws can transition from a closed position (for engaging the snap ring gap) to an open position (for releasing the snap ring), providing adaptability for different operational phases without requiring multiple separate tools.
2Measurement precision
If the jaw portions are designed to form a tongue that fits into the snap ring gap, then the precision of engagement is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The tips of the jaw portions are specifically shaped to form a tongue configuration that precisely matches the snap ring gap geometry. This localized precision is concentrated only at the critical engagement points (the tips), while the rest of the jaw portions can be manufactured with standard tolerances, balancing engagement precision with manufacturing feasibility.
3Ease of operation
If spring bias is applied to keep the jaw portions in a closed position, then the ease of operation is improved, but the force requirements and energy storage increase
Solution Approach 1:
The spring provides automatic biasing force that keeps the jaw portions in the closed position without requiring continuous user input. The spring self-regulates the engagement force, maintaining constant pressure on the snap ring to prevent accidental disengagement, while requiring minimal energy input from the user during normal operation.

Function Achieved in This Case
The snap ring pliers provide a convenient, efficient, and safe method for installing and removing snap rings, simplifying the process and reducing the time required for maintenance, while being easy to use and construct.
Implementation Method 1
An applied bias biases the first and second sections in the first position, which is applied by a spring coupled between the first and second sections

AI summary
Snap ring pliers include a first section having a first jaw portion with a first outer end and a first tip projecting outwardly from the first outer end, and a second section having a second jaw portion with a second outer end and a second tip projecting outwardly from the second outer end. The first tip opposes the second tip. A pivot pivotally couples the first section to the second section for movement of the first and second jaw portions between closed and open positions. The first and second tips are joined forming a tongue adapted to be received in a snap ring gap in the closed position of the first and second jaw portions, and the first and second tips are spaced apart and separated by a gap in the open position of the first and second jaw portions.
