Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If satellite dimensions are increased to optimize external development surface, repeater module surface, and radiative surface, then surface areas are improved, but launcher size requirements increase and cost increases
Solution Approach 1:
The satellite employs a variable master cross-section design where the repeater module's width in the east-west direction varies along the north-south axis. This dynamic geometric configuration allows optimization of surface areas (external development, repeater module, and radiative surfaces) while maintaining a compact overall dimensions that fit within conventional launcher constraints, thereby resolving the contradiction between maximizing surface areas and minimizing launcher size requirements
2Area of stationary object
If satellite dimensions are increased to optimize surface areas, then surface areas are improved, but manufacturing cost increases
Solution Approach 1:
The variable master cross-section repeater module optimizes the repeater module surface area through controlled variation of the east-west width along the north-south direction, achieving maximum surface area utilization without requiring excessive overall satellite size that would drive up manufacturing costs. The design maintains compatibility with conventional production processes while optimizing performance
Solution Approach 2:
The design varies the master cross-section parameter (width in east-west direction) along the length of the repeater module, creating an optimized surface area configuration. This parameter variation allows achieving the required repeater module surface area without proportionally increasing other dimensions that would escalate manufacturing costs
3Area of stationary object
If satellite dimensions are increased to optimize surface areas, then surface areas are improved, but the need for larger capacity launchers increases
Solution Approach 1:
The variable master cross-section design optimizes the radiative surface area by strategically varying the repeater module's width along its length, achieving maximum radiative surface within the constraints of conventional launcher dimensions. This allows the satellite to maintain high adaptability to different launcher types while still achieving the required radiative surface for thermal control
