Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sealed structure is used to protect electronic equipment from dust and raindrops, then protection from external contaminants is improved, but heat dissipation deteriorates
Solution Approach 1:
The sealed housing is segmented with multiple openings (first opening, second opening, third opening) that allow controlled air flow paths. The internal space is divided into regions through which air flows in sequence, creating segmented cooling channels that maintain sealing while enabling heat dissipation.
Solution Approach 2:
Air acts as an intermediary medium to transfer heat from the electronic equipment to the external environment. The air flow system uses the air as a carrier to remove heat while the housing structure filters and controls the air passage, preventing direct contact with contaminants.
2Object-affected harmful factors
If a sealed structure is used to protect electronic equipment, then protection from humidity is improved, but heat management deteriorates
Solution Approach 1:
The housing is segmented with multiple openings that create separate air flow paths for cooling. The first opening allows air intake, the second opening allows air discharge, and the third opening provides additional ventilation. This segmentation enables effective heat management while maintaining the sealed protective structure against humidity.
Solution Approach 2:
The invention uses pneumatic principles by utilizing air flow through the housing openings to manage heat. The air circulation system creates pressure differentials that drive cooling air through the internal channels, providing active heat management without compromising the sealed structure's humidity protection.
3Object-affected harmful factors
If electronic equipment is installed in a sealed space, then protection from external contaminants is improved, but temperature control deteriorates
Solution Approach 1:
The sealed housing is divided into multiple regions with controlled air flow paths. The first opening, second opening, and third opening create segmented channels that guide air flow over and around the electronic equipment, enabling temperature control while maintaining the sealed protective environment.
Solution Approach 2:
Air serves as an intermediary cooling medium that circulates through the housing openings and internal channels. This air flow system provides temperature control for the electronic equipment while the housing structure filters and controls the air passage, maintaining protection from external contaminants.
Applied Scientific Principles

Function Achieved in This Case
The apparatus effectively controls temperature and humidity within the sealed space, maintaining it at a level similar to external air temperature, enhancing heat exchange efficiency and dehumidification, thus protecting electronic equipment from heat and moisture.
Implementation Method 1
an external air channel forming unit (200) that suctions external air, which has temperature lower than temperature of the interior sealed space, from a side of a lower portion of a first surface (110) of the housing using a first fan disposed at an upper portion of the housing
Implementation Method 2
an internal channel forming unit (300) that suctions internal air at a relatively high temperature in the interior closed space using a second fan and a third fan respectively disposed on a second surface (120) and a third surface (130)
Implementation Method 3
a dehumidifier (400) that maintains humidity of the interior sealed space by removing humidity of the internal sealed space, including a porous anode (410), a porous cathode (420), a polymer electrolyte membrane (430) disposed between the porous anode and the porous cathode

AI summary
The present disclosure relates to an apparatus for protecting electronic equipment that is used in an interior sealed space, in which electronic equipment is installed, to prevent the temperature of the interior sealed space from increasing higher than external air due to heat generated by the electronic equipment positioned therein and to prevent humidity from being produced in the interior sealed space, the apparatus including: a housing (100) disposed on a wall of the interior sealed space; an external air channel forming unit (200) that suctions external air, which has temperature lower than temperature of the interior sealed space, from a side of a lower portion of a first surface (110) of the housing using a first fan disposed at an upper portion of the housing, sends upward the external air, and discharges the external air to a side of an upper portion of the first surface of the housing; and internal channel forming unit (300) that suctions internal air at a relatively high temperature in the interior closed space using a second fan and a third fan respectively disposed on a second surface (120) and a third surface (130) adjacent to the first surface of the housing such that the internal air suctioned through the second fan and the internal air suctioned through the third fan partially overlap the external air channel and hit against each other and the internal air descends and is then discharged from a lower portion of the second surface and a lower portion of the third surface of the housing.
