Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw shaft lock means is used to regulate rotation of the link member, then the gripping tool can prevent releasing of gripping, but the rotation operation of the screw shaft becomes troublesome and time-consuming
Solution Approach 1:
The patent replaces the screw shaft rotation mechanism with a one-way clutch mechanism that uses a pawl and ratchet wheel. This substitution eliminates the need for repeated rotation operations while maintaining the locking function, thereby improving ease of operation without compromising grip holding reliability.
Solution Approach 2:
The one-way clutch mechanism automatically locks in the gripping direction through the pawl engaging with the ratchet wheel teeth, without requiring manual intervention for each locking action. The mechanism serves itself by maintaining the locked state passively, reducing operational complexity.
2Reliability
If a screw shaft lock means is used to regulate rotation of the link member, then the gripping tool can regulate rotation effectively, but the operation becomes cumbersome especially with varying linear body thicknesses
Solution Approach 1:
The patent substitutes the complex screw shaft rotation mechanism with a simpler one-way clutch system consisting of a pawl, ratchet wheel, and spring. This new mechanism effectively regulates rotation in one direction while allowing free movement in the other, reducing operational complexity especially when dealing with varying linear body thicknesses.
Solution Approach 2:
The one-way clutch mechanism dynamically adapts to different gripping scenarios by allowing rotation in the gripping direction regardless of linear body thickness variations, while automatically preventing rotation in the release direction. This dynamic behavior simplifies operation across different work conditions.
3Reliability
If rotation operation of the screw shaft is required for locking, then the lock means can regulate rotation, but the workability deteriorates due to troublesome operations
Solution Approach 1:
The patent replaces the screw shaft mechanism with a one-way clutch mechanism that provides locking functionality without requiring rotation operations. The pawl automatically engages with the ratchet wheel to prevent rotation in the release direction, maintaining locking reliability while dramatically improving workability by eliminating tedious rotational operations.
Solution Approach 2:
The one-way clutch mechanism performs the locking function automatically through the engagement of the pawl with the ratchet wheel teeth. The spring-loaded pawl self-activates to engage or disengage based on the direction of force applied, eliminating the need for manual rotation operations and thereby improving productivity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The one-way clutch mechanism facilitates easy and secure gripping of linear bodies with minimal rotation effort, ensuring stability even with varying thicknesses, and allows quick release with a simple switching operation.
Implementation Method 1
a one-way clutch that blocks rotation of the link member or another member in conjunction with rotation of the link member in one direction and allows reverse rotation in the other direction
Implementation Method 2
The one-way clutch includes a ratchet wheel, a claw member, and an elastic member. The elastic member causes an elastic force working on the claw member.

AI summary
A wire gripper includes a second link arm, a connection member, a stationary-side wire gripping portion, and a moveable-side wire gripping portion. The second link arm is rotatably connected by a main body. The connection member is connected to the second link arm. The moveable-side wire gripping portion is movable in a direction approaching or being spaced from the stationary-side wire gripping portion in conjunction with movement of the connection member. The wire gripper includes a ratchet mechanism that blocks rotation of the operation lever in conjunction with rotation of the second link arm in one direction and allows reverse rotation in the other direction. The ratchet mechanism blocks rotation, so that movement of the moveable-side wire gripping portion in a direction being spaced from the stationary-side wire gripping portion.
