Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bus systems lack flexibility in design and fabrication, and do not efficiently allow for the attachment of devices while maintaining the main bus on the same centerline, which limits their adaptability and efficiency in electrical power distribution.
Innovation Solution
The electrical distribution bus system incorporates angled bus bars with dielectric insulators and fasteners, allowing for a break in the main bus while keeping it on the same centerline, enabling efficient attachment of devices and reducing material usage and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bus bars are completely surrounded with insulation, then manufacturing cost is reduced, but design flexibility and fabrication adaptability are limited
Solution Approach 1:
The bus bar system is segmented into modular components with standardized elbow angles (e.g., 45°, 90°, 135°) that can be combined in various configurations. This segmentation allows the bus bar to adapt to different spatial arrangements and device attachment requirements while maintaining a standardized manufacturing process for each module.
Solution Approach 2:
The standardized elbow portions and connection configurations serve multiple functions: they provide structural support, enable various routing configurations, facilitate device attachment at different angles, and maintain electrical continuity. This multi-functionality reduces the need for custom-designed components.
2Ease of manufacture
If bus bars are designed with fixed configurations, then manufacturing is simplified, but the ability to attach devices while maintaining centerline alignment is limited
Solution Approach 1:
The bus bar system incorporates standardized elbow portions that can be oriented in multiple standard angles (45°, 90°, 135°), allowing the configuration to be dynamically adjusted during assembly to accommodate different device positions and routing requirements while maintaining centerline alignment, without requiring custom fabrication for each scenario.
3Strength
If bus bars use traditional connection methods, then structural integrity is maintained, but heat dissipation efficiency is reduced
Solution Approach 1:
The bus bar cross-section utilizes curved or rounded contours instead of sharp corners, which improves stress distribution and structural integrity while also enhancing heat dissipation by reducing stress concentration points and improving surface area utilization for thermal radiation and convection.
