Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable is inserted into the channel via the shaft, then the cable can be laid in the wastewater pipe, but high friction and deflection at the edge cause cable damage and insertion difficulties
Solution Approach 1:
The cable run element is divided into multiple links that can pivot relative to each other, allowing the cable to be guided through the shaft edge in segments rather than as a single rigid structure, reducing friction and deflection damage
Solution Approach 2:
The cable run element acts as an intermediary device between the cable and the shaft edge, with its pivotable links and guide elements facilitating smooth cable passage through the edge region without direct cable-to-edge contact
2Reliability
If complicated mechanisms are used to screw together the shaft and channel, then the device can be securely assembled, but assembly becomes expensive and time-consuming
Solution Approach 1:
The device is segmented into modular links that can be easily assembled and disassembled without complex screwing mechanisms, maintaining stability through the pivotable connection design while significantly reducing assembly time and cost
Solution Approach 2:
The rigid screwing connection is replaced with dynamic pivotable links that provide sufficient stability for cable running while allowing quick assembly and disassembly operations
3Ease of operation
If the cable run element is designed with pivotable links and guide elements, then cable insertion is facilitated and entanglement is avoided, but the device structure becomes more complex
Solution Approach 1:
The cable run element is segmented into multiple identical links, each with integrated guide elements, creating a modular structure that facilitates cable routing while keeping individual link complexity manageable through standardization
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 cable run element can be easily aligned and secured within the shaft, preventing cable escape and simplifying the insertion process, reducing assembly time and costs, and ensuring stability without the need for additional anchoring.
Implementation Method 1
counterweights that are arranged in an end region of the parallel plates opposite the end region on at least two links, so that the center of gravity of the cable run element lies in its starting position, in particular in its freely suspended position, in the receptacle between the guide elements and the opposite end regions
