Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing satellite structures require complex and costly intermediate support structures for launch, which are not generic, modular, or adaptable to different satellite sizes and geometries, leading to increased mass, design complexity, and development costs.
Innovation Solution
A satellite structure featuring a circular launcher interface ring with directly supported primary walls and a quasi-point connection system, eliminating the need for intermediate support structures, allowing for a lightweight, modular, and adaptable design that can accommodate various satellite sizes and geometries using a limited number of basic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an intermediate support structure is used to connect the launcher interface ring to the equipment-carrying walls, then the satellite can withstand launch forces, but the structure mass and device complexity increase significantly
Solution Approach 1:
The invention extracts and eliminates the intermediate support structure from the satellite design, directly connecting the equipment-carrying walls to the launcher interface ring. This removal of the unnecessary intermediate component simplifies the structure while maintaining strength through direct load transfer paths from the walls to the ring.
Solution Approach 2:
The invention merges the functions of the intermediate support structure into the equipment-carrying walls themselves, which are designed to directly bear and transmit launch loads to the launcher interface ring. This consolidation eliminates redundant components and reduces overall structural complexity.
2Strength
If an intermediate support structure is used, then the satellite can support equipment walls, but the structure mass increases
Solution Approach 1:
The invention removes the intermediate support structure that adds unnecessary mass, allowing the equipment-carrying walls to directly support themselves and transmit loads to the launcher interface ring, thereby reducing the overall moving mass of the satellite.
3Adaptability or versatility
If a non-generic intermediate support structure is designed for each satellite type, then the satellite can be optimized for specific missions, but the development cost and manufacturing complexity increase
Solution Approach 1:
The invention creates a universal launcher interface ring design that can accommodate different satellite types and missions without requiring custom intermediate support structures. The equipment-carrying walls are designed to directly interface with this standardized ring, providing mission-specific optimization while maintaining manufacturing simplicity and reducing development costs through reuse of the same basic interface components.
4Adaptability or versatility
If a complex intermediate support structure is used, then the satellite can accommodate various geometries, but the adaptability to different satellite sizes and geometries decreases
Solution Approach 1:
The invention removes the intermediate support structure that limited adaptability, allowing the equipment-carrying walls to directly interface with the launcher interface ring. This enables greater flexibility in accommodating different satellite sizes and geometries while maintaining compatibility with various launchers through the standardized ring interface.

AI summary
The invention relates to a satellite having a structure that includes a circular launching interface ring (1) and at least two main planar apparatus-holding walls (5) that are substantially parallel to the axis (A) of the ring (1) and rigidly connected to one another and to the ring (1). Each wall (5) directly bears on the ring (1) by a base (6) of the wall (5), and each wall (5) is rigidly and directly attached to the ring (1) by at least one somewhat point-by-point connection (7) on at least one point or area of tangency or intersection with the base (6) of the wall (5) and the ring (1).
