Counterweighted Rotating Tool Holder for Boom Arm Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool holders on boom mechanisms are fixedly attached, positioning tools out of reach during arm rotation, causing inconvenience and safety hazards due to the need for manual tool repositioning and increased risk of accidents.
Innovation Solution
A rotating tool holder apparatus with a cylindrical base and shell, featuring a counterweight, that automatically adjusts the tool's position as the boom flips, ensuring the tool remains accessible and safe for the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed tool holder is attached to the boom arm, then the tool can be securely held in one position, but the tool becomes inaccessible and dangerous when the boom arm rotates or flips
Solution Approach 1:
The tool holder is made rotatable relative to the boom arm, allowing it to dynamically adjust its position. The holder can rotate 360 degrees around the boom arm axis, enabling the operator to access the tool regardless of the boom arm's orientation, while maintaining secure attachment through the rotatable connection mechanism
Solution Approach 2:
A counterweight mechanism is incorporated into the tool holder assembly to balance the tool's weight. This allows the holder to remain stable and controllable during rotation, preventing the tool from swinging uncontrollably or becoming inaccessible due to gravitational effects when the boom arm is in various positions
2Object-affected harmful factors
If the operator removes the tool from the fixed holder before flipping the boom, then safety is improved, but operational efficiency decreases due to repeated tool handling
Solution Approach 1:
The rotatable tool holder allows the tool to remain securely attached during boom arm rotation and flipping operations. The holder's ability to rotate independently ensures the tool stays accessible and properly positioned regardless of boom orientation, eliminating the need for manual removal and reattachment
Solution Approach 2:
The tool holder system automatically adapts its orientation to maintain optimal tool position relative to the operator and work area. The rotatable connection self-adjusts during boom movements, providing continuous tool accessibility without requiring operator intervention for repositioning or reattachment
3Ease of operation
If the operator holds the tool with one hand during boom maneuvers, then tool control is maintained, but the operator's ability to perform two-handed tasks is limited and safety is reduced
Solution Approach 1:
The rotatable tool holder maintains positive engagement with the tool during all boom arm movements, providing secure control without requiring the operator's manual holding. The dynamic rotation capability ensures the tool remains in an accessible and controlled position regardless of boom orientation, freeing both of the operator's hands for task performance
