Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport devices experience reduced service life and instability due to strong forces encountered during starting, braking, and transporting heavy workpieces, which affects their reliability and operational safety.
Innovation Solution
Incorporating a pendulum device that connects the towing vehicle and support structure, allowing energy from impacts to be converted into lifting the load beam, thereby absorbing forces and enhancing stability and reliability. Additionally, the pendulum device is designed as a rod with articulated fastening elements for improved stability and the integration of a coupling device for flexible material flow systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the transport device operates with heavy workpieces and undergoes frequent starting and braking, then the transport capacity and productivity are improved, but the service life and reliability deteriorate due to strong forces acting on the transport device
Solution Approach 1:
The pendulum device is pre-installed between the towing vehicle and support structure to provide cushioning before impact occurs. During operation, when strong forces act on the towing vehicle during starting or braking, the pendulum device absorbs these forces through controlled movement, preventing direct transmission to the support structure and thereby extending service life while maintaining transport capacity
2Speed
If the transport device accelerates or brakes heavily to improve operational efficiency, then the productivity increases, but the stability and reliability worsen due to strong forces acting on the transport device
Solution Approach 1:
The pendulum device introduces dynamic flexibility to the connection between the towing vehicle and support structure. Instead of a rigid connection that transmits all forces directly, the pendulum allows controlled movement and energy absorption, converting impact energy into lifting motion of the load beam. This dynamic response maintains stability during rapid acceleration and braking while enabling improved operational efficiency
