Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electrical components are arranged compactly in power distribution apparatus, then device complexity is reduced and space is saved, but insulativity between electrical connection structures deteriorates leading to poor reliability
Solution Approach 1:
The patent introduces an insulating member as an intermediary element positioned between the first and second electrical connection structures. This insulating member physically separates the two connection structures while maintaining their functional proximity, thereby preventing direct electrical contact and ensuring reliable insulation without requiring increased spacing between components.
2Productivity
If spacing between electrical connection structures is reduced for compact arrangement, then productivity and space utilization improve, but short circuit risk increases due to poor insulativity
Solution Approach 1:
The insulating member serves as a mediator that enables close spacing between electrical connection structures while preventing harmful electrical contact. By introducing this intermediate insulating element, the design achieves high space utilization without compromising safety, as the insulating member blocks the harmful factor of direct electrical contact that would lead to short circuits.
3Reliability
If insulating member is added between electrical connection structures, then reliability and insulativity are enhanced, but device complexity and structural simplicity are reduced
Solution Approach 1:
The insulating member is designed as a thin film or sheet structure that can be easily positioned between the electrical connection structures. This thin-film approach provides effective insulation without adding significant structural complexity or volume, maintaining the overall simplicity of the power distribution apparatus while enhancing reliability.
4Reliability
If insulating member is positioned at the shortest distance location between electrical connection structures, then insulativity at the critical point is enhanced, but manufacturing precision requirements increase
Solution Approach 1:
The insulating member is integrated with either the first or second electrical component housing, merging the insulation function with the existing structural elements. This integration eliminates the need for separate positioning operations and reduces manufacturing precision requirements, as the insulating member is automatically positioned at the correct location during assembly of the integrated component.
