Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual lifting and transporting is used, then no complex equipment is needed, but personnel safety deteriorates and physical strain increases
Solution Approach 1:
A robotic arm system serves as an intermediary between the payload and human operators. The robotic arm includes multiple joints with actuators that can be controlled remotely or autonomously to perform lifting and transporting tasks, eliminating direct human contact with heavy loads while maintaining operational control.
Solution Approach 2:
The patent replaces manual mechanical lifting with an automated robotic mechanical system. The robotic arm uses electric or hydraulic actuators to generate the forces needed for lifting, substituting human muscular effort with controlled mechanical actuation systems that provide precise force application and motion control.
2Productivity
If limited functionality assistance systems are used, then some lifting support is provided, but effectiveness deteriorates for certain tasks
Solution Approach 1:
The robotic arm system incorporates dynamic control capabilities with multiple degrees of freedom and adjustable actuation forces. The system can adapt its motion patterns, speed, and force application in real-time based on payload characteristics and task requirements, providing versatile functionality for various lifting and transporting scenarios.
Solution Approach 2:
The system allows for parameter adjustments including actuator force levels, joint motion ranges, control loop gains, and end-effector configurations. These parameter changes enable the system to adapt to different payload weights, sizes, and handling requirements, significantly improving lifting effectiveness across diverse tasks.
3Productivity
If heavy payloads are lifted manually, then no additional equipment is required, but operational efficiency deteriorates and injuries increase
Solution Approach 1:
The patent extracts the hazardous lifting function from human operators and assigns it to the robotic arm system. The robotic arm takes on the burden of handling heavy payloads, including lifting, positioning, and transporting, while human operators remain in control stations away from physical dangers, eliminating orthopedic injuries and improving operational efficiency.
4Ease of operation
If teleoperated robotic system is implemented, then physical strain on personnel is reduced, but system complexity increases
Solution Approach 1:
The robotic arm system is designed as a multi-functional platform that can perform various lifting and transporting tasks through a single integrated structure. The system includes universal joints, standardized actuators, and programmable control that enable it to handle different payload types and operations, reducing the need for multiple specialized devices while maintaining ease of operation.

AI summary
A teleoperated robotic system that includes master control arms, slave arms, and a mobile platform. In use, a user manipulates the master control arms to control movement of the slave arms. The teleoperated robotic system can include two master control arms and two slave arms. The master control arms and the slave arms can be mounted on the platform. The platform can provide support for the master control arms and for a teleoperator, or user, of the robotic system. Thus, a mobile platform can allow the robotic system to be moved from place to place to locate the slave arms in a position for use. Additionally, the user can be positioned on the platform, such that the user can see and hear, directly, the slave arms and the workspace in which the slave arms operate.
