Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If busbars are arranged in conventional orientation within existing electrical busway assembly, then electrical power distribution is achieved, but current leakage occurs resulting in huge drop in efficiency and creating electromagnetic forces during faulty events
Solution Approach 1:
The busbars are arranged in an asymmetric configuration where they are not parallel to each other but are instead positioned at different angles or orientations within the busway assembly. This asymmetric arrangement disrupts the symmetrical current paths that cause leakage and electromagnetic forces, thereby reducing energy loss while maintaining electrical continuity.
Solution Approach 2:
An intermediate insulating structure or positioning element is introduced between the busbars to control their spatial relationship. This intermediary component ensures proper electrical isolation and positioning, preventing direct contact and reducing current leakage paths while maintaining the structural integrity of the assembly.
2Adaptability or versatility
If multiple tap-off power outlets are installed along the busway, then flexibility in installing plug-in devices is improved, but insulation between busbars becomes critical and existing insulating techniques are not compatible
Solution Approach 1:
The busway assembly is segmented into multiple sections with individual insulating members positioned at regular intervals between busbars. Each segment can independently accommodate tap-off outlets while maintaining proper insulation. This segmentation allows multiple plug-in devices to be installed along the busway without compromising the insulation integrity between different phases.
Solution Approach 2:
Dedicated insulating members are introduced as intermediary elements between the busbars throughout the length of the busway. These insulating members provide continuous electrical isolation, enabling the installation of multiple tap-off outlets at various locations while maintaining reliable insulation between busbars carrying different phases.
3Reliability
If air gaps are introduced between shaped bars to provide electrical insulated spacing, then arcing between different phases is prevented, but leakage current flows through conductive busbars creating eddy current
Solution Approach 1:
The busbars are positioned in an asymmetric arrangement that prevents parallel alignment, thereby disrupting the formation of closed loops that generate eddy currents. By eliminating the symmetrical parallel configuration, the asymmetric positioning reduces eddy current losses while maintaining adequate spacing to prevent arcing between phases.
Solution Approach 2:
Insulating members are introduced as intermediary elements between busbars to provide both spacing and electrical isolation. These intermediaries prevent direct conductive paths that would create eddy currents while maintaining the necessary air gaps or insulation barriers to prevent arcing between different phases.
4Productivity
If conventional busway assembly is used, then electrical power distribution is achieved, but user has to subsist in an unsafe work environment due to current leakage and electromagnetic forces
Solution Approach 1:
The asymmetric busbar arrangement eliminates the symmetrical current paths that generate harmful electromagnetic forces and leakage currents. This asymmetric configuration reduces electromagnetic interference and creates a safer working environment while maintaining effective electrical power distribution capability.
Solution Approach 2:
Insulating members are introduced as intermediary elements throughout the busway assembly to provide continuous electrical isolation. These intermediaries reduce current leakage and minimize electromagnetic forces, thereby creating a safer work environment for users while maintaining productive electrical power distribution.
