Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sling chain is used to secure the underground construction element, then the element can be lifted and positioned, but the risk of uncontrolled toppling increases in the event of chain failure
Solution Approach 1:
The invention incorporates an energy absorber into the securing device before operation begins. This energy absorber is pre-positioned to cushion and absorb kinetic energy in advance, preventing uncontrolled toppling if the sling chain fails during lifting or positioning operations.
Solution Approach 2:
The energy absorber acts as an intermediary element between the sling chain and the underground construction element. It mediates the force transmission, absorbing excessive kinetic energy and preventing direct transmission of harmful forces that could cause uncontrolled toppling.
2Adaptability or versatility
If the sling chain is used as a securing device, then it can connect the element to the machine, but uncontrolled kinetic energy release occurs upon failure
Solution Approach 1:
The invention converts the harmful kinetic energy released upon sling chain failure into beneficial absorbed energy through the energy absorber. The energy absorber is designed to capture and dissipate the kinetic energy that would otherwise cause uncontrolled toppling, transforming a harmful effect into a controlled energy management system.
Solution Approach 2:
The energy absorber serves as an intermediary that manages kinetic energy between the sling chain and the underground construction element. It controls and limits the kinetic energy transmission, preventing uncontrolled release while maintaining the securing and connecting functions of the overall system.
3Device complexity
If a simple sling chain is used, then the device complexity is low, but the safety risk increases due to lack of energy absorption capability
Solution Approach 1:
The energy absorber is integrated into the securing device structure in advance, providing cushioning capability before any failure occurs. This pre-integrated energy absorption mechanism adds minimal complexity to the device while significantly reducing safety risks associated with kinetic energy release.
Solution Approach 2:
The invention merges the energy absorber with the securing device (sling chain assembly) into an integrated system. This combination maintains relatively simple device structure while incorporating essential energy absorption functionality, achieving a balance between complexity and safety.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The securing device effectively reduces the risk of uncontrolled kinetic energy release by absorbing and conducting away the energy absorber, thereby reducing the forces that act on the securing device and the securing device.
Implementation Method 1
By means of the energy absorber, the result is achieved, in the event of a failure of the lifting tackle, that the drop energy of the underground construction element is absorbed and conducted away, and thereby the forces that act on the securing device are reduced.
