Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional electric vehicle manufacturing techniques are used, then production quality and reliability are maintained, but manufacturing cost and complexity increase significantly
Solution Approach 1:
The electric motorbike is divided into modular components including a frame module, powertrain module with electric motor and battery, suspension module, and bodywork module. Each module can be manufactured independently and assembled through mechanical fastening, reducing overall manufacturing complexity and cost while maintaining quality standards
Solution Approach 2:
The stainless steel frame serves multiple functions: structural support, mounting platform for components, and aesthetic element. The belt assembly provides both power transmission and structural connection functions. This multi-functionality reduces the number of separate components needed, simplifying manufacturing
2Productivity
If modular design is implemented for large-scale production, then manufacturing efficiency and accessibility improve, but structural integrity and reliability may be compromised
Solution Approach 1:
The vehicle is segmented into modular components that can be produced independently and assembled efficiently. The frame uses standardized mechanical fastening points and reinforcement panels at stress concentrations, ensuring structural integrity is maintained while enabling modular assembly for large-scale production
Solution Approach 2:
The frame combines stainless steel materials with reinforced panels at critical structural points. This composite approach maintains structural integrity while allowing modular assembly, as the reinforced panels can be pre-fabricated and attached through standardized mechanical fastening processes
3Ease of manufacture
If stainless steel frame with mechanical fastening is used, then ease of assembly and modular production are improved, but manufacturing precision requirements increase
Solution Approach 1:
The frame is segmented into modules with standardized fastening interfaces. Pre-drilled holes, aligned mounting points, and standardized bolt patterns are incorporated into the design, reducing the precision requirements during final assembly while maintaining ease of assembly through mechanical fastening
Solution Approach 2:
Critical alignment features and mounting points are pre-formed during frame fabrication. The stainless steel frame includes pre-positioned fastening points and alignment features that reduce the precision requirements during final assembly operations, making the assembly process easier while maintaining manufacturing standards
4Reliability
If cooling fins are added to electric motor, then heat dissipation and motor reliability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
Cooling fins are added only to the electric motor where heat generation occurs, rather than throughout the entire vehicle. This localized approach improves motor reliability through better heat dissipation while minimizing the increase in overall device complexity and manufacturing cost
