Power Tool for Ground Cover Attachment Pin Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for manipulating ground cover attachment pins are often difficult to use, inefficient, require manual torque, and are not fully automated, making it challenging to securely lock or unlock pins, especially in harsh weather conditions and uneven surfaces.
Innovation Solution
A power tool with a carrier, gripper, and rotator that selectively positions over the attachment pin, gripping and rotating it to lock or unlock it relative to the ground covers, utilizing a power-driven actuator for efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tools are used to manipulate attachment pins, then device complexity is reduced, but operator effort and time consumption increase significantly
Solution Approach 1:
The patent replaces manual mechanical manipulation with a power-driven system. The attachment pin manipulation tool includes a motor or actuator that automatically rotates the attachment pin to lock or unlock it, eliminating the need for operators to manually apply torque. This substitution of mechanical manual operation with automated power-driven operation directly reduces operator effort while managing device complexity through integrated design.
2Productivity
If existing manual tools are used, then device complexity remains low, but productivity and efficiency decrease due to time-consuming operations
Solution Approach 1:
The attachment pin manipulation tool is designed to perform operations autonomously once positioned. The power-driven actuator automatically executes the locking or unlocking sequence without requiring continuous operator intervention. The tool self-adjusts and completes the manipulation cycle, improving productivity by reducing the time per operation while the automation is contained within a single integrated device rather than a complex system.
3Reliability
If manual torque application is used, then device complexity is minimized, but reliability decreases in harsh weather conditions and uneven surfaces
Solution Approach 1:
The patent replaces inconsistent manual torque application with a controlled power-driven actuator system. The motor or actuator delivers consistent, repeatable torque regardless of environmental conditions such as freezing weather or uneven surfaces. This substitution ensures reliable locking and unlocking operations by eliminating human fatigue and variability, with the actuator system integrated into a portable tool that can be positioned as needed.
4Ease of operation
If existing tools require bending and manual positioning, then device complexity stays low, but ease of operation and operator safety worsen
Solution Approach 1:
The attachment pin manipulation tool is divided into functional segments: a carrier for positioning, a gripper for holding the attachment pin, and a power-driven actuator for rotation. This segmentation allows each component to perform its specific function efficiently. The carrier provides stable positioning without requiring operator bending, while the gripper securely holds the pin for automated manipulation, improving ease of operation through ergonomic design and functional specialization.

AI summary
A power tool for unlocking a releasable attachment pin from at least two ground covers includes at least one gripper carried by a carrier and selectively moveable relative to the carrier to grip a first portion of the attachment pin. At least one rotator also carried by the carrier is selectively rotatable relative to the first portion of the attachment pin to rotate a second portion of the attachment pin to unlock the attachment pin from the ground covers. A power-driven actuator associated with the carrier is operatively coupled to the rotator(s) and configured to selectively rotate the rotator(s).
