Solution Overview
Problem
Conventional space probing land rovers face challenges in enhancing the thermal protective function for electronic apparatuses and batteries with narrow permissible temperature ranges, particularly in protecting them from ultralow temperatures while minimizing energy usage.
Innovation Solution
The space probing apparatus employs an inner housing with a heat dissipating body and a thermal insulating material, coupled with an outer housing that forms a thermal insulating layer using a vacuum or dilute atmosphere, allowing for efficient heat management by minimizing heat radiation at night and dissipating heat during the day through a lid and thermal louver system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thermal protection measures are used for electronic apparatuses and batteries, then protection from ultralow temperature is achieved, but energy consumption increases and thermal protective function is insufficient
Solution Approach 1:
The patent implements a nested housing structure where an inner housing containing electronic apparatuses and batteries is placed inside an outer housing. This nested configuration creates multiple thermal insulation layers, enhancing protection against ultralow temperatures while minimizing the need for additional active heating systems, thereby reducing energy consumption.
Solution Approach 2:
The patent introduces a vacuum or dilute atmosphere between the inner and outer housings to create a thermal insulation layer. This inert environment eliminates heat conduction and convection, providing passive thermal protection that reduces energy consumption while maintaining reliable operation of temperature-sensitive components.
2Reliability
If heat dissipation structures are added to protect from high temperature, then thermal protection is improved, but device complexity increases
Solution Approach 1:
The patent incorporates a movable lid and thermal louver structure that can dynamically adjust between open and closed states. During daytime, the lid opens and louvers extend to dissipate heat; during nighttime, the lid closes and louvers retract to retain heat. This dynamic adaptability provides effective thermal protection across varying conditions without requiring complex active control systems.
Solution Approach 2:
The lid and housing structure serve multiple functions: they provide structural enclosure, enable passive thermal insulation when closed, and facilitate active heat dissipation when opened with extended louvers. This multi-functionality achieves comprehensive thermal protection from both high and low temperatures while minimizing the number of separate components needed.

Function Achieved in This Case
This configuration significantly enhances the thermal protective function for electronic apparatuses and batteries, effectively protecting them from both ultralow and high temperatures using minimal energy, maintaining battery temperature and preventing overheating.
Implementation Method 1
forms a thermal insulating layer between the inner housing and the outer housing using a space therebetween. The space probing apparatus is used in probing activities on the moon and planets and, therefore, the state of the space that is the thermal insulating layer is a vacuum or a dilute atmosphere.

AI summary
A space probing apparatus is provided that can further enhance its thermal protective function for electronic apparatuses and batteries that are apparatuses each having a narrow range of permissible temperature.The space probing apparatus includes, as a vehicle body 1 that is an apparatus body, an inner housing 13 that accommodates an electronic apparatus 11 and a battery 12, and an outer housing 15 that accommodates the inner housing 13 supporting the inner housing 13 afloat therein. A thermal insulating layer 16 is formed between the inner housing 13 and the outer housing 15 using a space therebetween. A heat dissipating body 17 is included in an upper portion of the inner housing 13. A lid 18 is included in an upper portion of the outer housing 15. The whole outer faces of the inner and the outer housings 13 and 15 are each covered with a thermal insulating material 20. Thereby, in the nighttime, the temperature of the battery 12 is maintained using the least necessary amount of heat generated and, thereby, the electronic apparatus 11 and the battery 12 are protected from an ultralow temperature. In the daytime, the lid 18 is opened and heat is discharged using the heat dissipating body 17 and, thereby, the electronic apparatus 11 and the battery 12 are protected from a high temperature.
