Load Handling Lever Unit With Remote Mounting and Return Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard type load handling devices struggle to operate large or differently shaped baggage due to interference from the baggage's shape, making it difficult to use the standard operation part, and require a separate operation part for large load type devices, which complicates integration and operation.
Innovation Solution
An operation unit with a lever shaft, plate, and cover flanges that can be integrated into a box-shaped main body or control part, featuring a rotation restraint mechanism and potentiometer, allowing for attachment to either the standard type operation part or the control part of a power load part, enabling unified operation across different load handling scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the operation part is provided adjacent to the load part in a standard type load handling device, then the operation part can be easily integrated into the device structure, but the operation part becomes disturbed by large or differently shaped baggage, making it difficult to operate
Solution Approach 1:
The operation part is separated from the load part and integrated into the box-shaped main body structure, creating distinct functional zones that prevent interference between the operating lever and large baggage while maintaining easy integration into the device
2Ease of operation
If a separate operation part is provided for large load type devices with power load parts, then the operation can be performed without interference from baggage shape, but the device complexity increases due to separate manufacturing and attachment
Solution Approach 1:
A single integrated operation part design serves both standard type and large load type devices, eliminating the need for separate operation parts while maintaining ease of operation without baggage interference through its integration into the box-shaped main body
3Power
If the arm mechanism is designed for large load capacity, then the device can handle heavy baggage, but the arm mechanism becomes large and heavy, requiring a different operation part configuration
Solution Approach 1:
The integrated operation part design provides universal applicability across different load capacities, allowing the same operation part configuration to serve both standard and large load type devices without requiring separate designs or attachments

AI summary
An operation unit includes a lever shaft having an operating lever at one end thereof and orthogonal to the operating lever, a plate with a flange having a bearing of the lever shaft, the other end-side of the lever shaft being arranged with penetrating the plate with a flange from a front surface thereof, a rotation restraint part for the lever shaft fixed to the lever shaft behind the plate with a flange and having a self-return function of forward and reverse rotations of the lever shaft, a cover with a flange covered on a backside of the plate with a flange in a form of sandwiching the rotation restraint part, a tip end-side of the lever shaft penetrating the cover with a flange via a bearing, and a potentiometer provided on a backside of the cover with a flange, rotation of the lever shaft being transmitted to the potentiometer.
