Solution Overview
Problem
The development of space equipment that can withstand harsh environmental conditions such as rapid temperature changes, shock, vibration, radiation, and electromagnetic waves is costly and complex, limiting the use of industrial electronic components due to increased size, weight, and power requirements, and poses risks due to the difficulty in multiplexing components.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If space-grade electronic components are used to withstand harsh space environments, then reliability is improved, but cost, size, weight, and power consumption increase significantly
Solution Approach 1:
The housing is divided into multiple functional layers including electromagnetic wave shielding layer, solar heat shielding layer, heat transfer layer, and radiation shielding layer. Each layer performs a specific protective function, allowing the use of standard electronic components while providing comprehensive environmental protection through distributed specialized layers rather than requiring single-component space-grade parts
Solution Approach 2:
The composite wall structure acts as an intermediary between the harsh space environment and the electronic components inside. This intermediary protective barrier filters electromagnetic waves, blocks solar heat, transfers heat away from components, and shields against radiation, enabling the use of lighter, cheaper standard components that would otherwise be damaged by direct environmental exposure
2Reliability
If complex auxiliary devices are added to protect electronic components in space, then protection capability is improved, but device complexity and development time increase
Solution Approach 1:
Multiple protective functions (electromagnetic shielding, thermal management, radiation protection) are merged into a single integrated composite wall structure. This unified housing design combines what would traditionally require separate auxiliary devices into one cohesive protective barrier, reducing overall system complexity while maintaining comprehensive protection capabilities
Solution Approach 2:
The composite wall structure serves multiple functions simultaneously: it provides electromagnetic wave shielding, solar heat shielding, heat transfer, and radiation shielding. This multi-functional design eliminates the need for separate specialized devices for each protection type, reducing device complexity while maintaining robust protection against all space environmental hazards
3Ease of manufacture
If industrial electronic components are used instead of space-grade components, then cost is reduced, but protection against environmental stressors becomes insufficient
Solution Approach 1:
The housing design converts harmful environmental factors into manageable conditions for standard components. The electromagnetic wave shielding layer converts harmful EM radiation into blocked waves, the solar heat shielding layer converts harmful solar heating into blocked thermal energy, and the heat transfer layer converts accumulated heat into transferred thermal energy that can be dissipated, allowing industrial components to operate safely in space environments
Solution Approach 2:
The composite wall structure acts as an intermediary protective barrier between industrial electronic components and harsh space environmental stressors. This intermediary filters and manages electromagnetic waves, solar heat, and radiation before they reach the components, enabling the use of cost-effective industrial components that would otherwise be damaged by direct environmental exposure

AI summary
The present invention relates to a housing that may apply industrial electronic components even in a space environment, and more particularly, to a universal mounting housing mounted on space equipment used in a space environment and housing a plurality of electronic components. The universal mounting housing may include a composite wall that constitutes an outer appearance of the housing to form a sealed inner space, a heat emitter that is formed inside or outside the composite wall to emit internal heat, and a connector pad that is formed on one side of the housing and is formed so that the electromagnetic wave filter communicates an inner space with an outside.
