Crane Machine Claw Gripper with Limiting Columns for Stable Grasping

The patent applies dynamics by making the claw device adjustable between different operating modes (first and second modes) that can be switched based on the player's age group. The device transitions from a fixed low-success-rate design for adults to an adjustable system that can provide high-success-rate mode for children, thereby adapting the reliability parameter to different user demographics while maintaining challenge for adults.

The patent changes the parameter of capture success rate by introducing adjustable mechanisms that modify the claw's gripping force and movement characteristics. Through parameter changes in the actuating assembly and limiting columns, the device can alter its operational parameters to achieve either high or low success rates depending on the intended player demographic.

The patent introduces limiting columns as intermediary components between the ropes and the fixed disk/pivot plate. These limiting columns act as mediators that guide and constrain the rope movement, preventing excessive tilting and detachment while still allowing necessary adjustment. The limiting columns provide a controlled interface that balances ease of operation with operational stability.

The patent applies local quality by providing different degrees of freedom to different parts of the system. The limiting columns provide localized constraints in specific directions while allowing movement in other directions. This selective constraint approach maintains stability where needed (preventing tilting) while preserving ease of operation where required (allowing adjustment).
