Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If granular hygroscopic materials are placed inside a shell, then the materials can be contained and structured, but the production cost increases due to shell material and manufacturing
Solution Approach 1:
The invention extracts and eliminates the shell component from the traditional dehumidifier structure. Instead of containing granular hygroscopic materials in a shell, the materials are directly formed into a solid ingot shape that contains itself, removing the need for additional shell material and manufacturing processes.
Solution Approach 2:
The invention changes the physical state and form of the hygroscopic materials from loose granules to a solid ingot structure. This parameter change in material form allows the materials to maintain their containment and structural integrity without requiring an external shell.
2Stability of the object's composition
If granular hygroscopic materials are placed inside a shell, then the materials can be contained, but the contact area between materials and humid air is reduced, lowering hygroscopic efficiency
Solution Approach 1:
The invention utilizes the porous structure of the hygroscopic materials in their solid ingot form. The porous nature allows humid air to penetrate deeply into the material interior, maximizing the contact area between the hygroscopic surfaces and humid air, thereby enhancing hygroscopic efficiency without requiring a shell containment structure.
3Stability of the object's composition
If a shell is used to accommodate hygroscopic materials, then the materials can be contained, but the assembly procedure becomes complex and production costs increase
Solution Approach 1:
The invention merges the containment function and the hygroscopic material into a single integrated solid ingot structure. The hygroscopic materials themselves form the containing structure through their solid ingot shape, eliminating the need for separate shell and material components, thus simplifying the assembly procedure to merely installing the pre-formed ingot.
4Stability of the object's composition
If granular hygroscopic materials are placed inside a shell, then the materials can be contained, but the heat energy transfer during drying is slow, increasing time and energy consumption
Solution Approach 1:
The porous structure of the solid hygroscopic ingot allows heat energy to penetrate and distribute uniformly throughout the material during the drying process. The porosity creates numerous internal pathways for heat transfer, significantly accelerating the drying rate and reducing both time and energy consumption compared to granular materials in a shell.
5Stability of the object's composition
If a shell is used to accommodate hygroscopic materials, then the materials can be contained, but the shell must be disassembled for waste sorting, making recycling inconvenient
Solution Approach 1:
The invention extracts and removes the shell component from the system, leaving only the solid hygroscopic ingot. This elimination of the shell simplifies the end-of-life disposal and recycling process, as the single-component ingot can be directly sorted and processed without the need for disassembly or separation from shell materials.
6Duration of action of stationary object
If an air duct is installed in the shell to deliver hot air, then the hygroscopic materials can be dried, but the perforations become obstacles to hot air flow, reducing the amount of hot air received
Solution Approach 1:
The porous structure of the solid hygroscopic ingot eliminates the need for air ducts and perforations. Hot air can directly contact and penetrate the porous material from all directions, providing unobstructed airflow paths and maximizing the amount of hot air that reaches the hygroscopic materials for efficient drying.
7Duration of action of stationary object
If an air duct is installed in the shell, then hot air can be delivered to hygroscopic materials, but the wall surface shields the materials, reducing the heating area
Solution Approach 1:
The invention extracts and removes the air duct structure from the system. Without the air duct wall surface to shield the hygroscopic materials, the entire external surface of the solid ingot becomes accessible to hot air, maximizing the heating area for efficient drying.
Solution Approach 2:
The porous structure of the solid hygroscopic ingot allows hot air to penetrate throughout the material volume, effectively utilizing both the external surface area and the internal porous surface area for heat transfer, thereby significantly increasing the total heating area available for drying.
8Duration of action of stationary object
If an air duct is installed in the shell, then hot air can be delivered, but the volume of the air duct reduces the space for hygroscopic materials, decreasing material capacity
Solution Approach 1:
The invention extracts and removes the air duct structure from the system. Without the air duct occupying internal volume, the entire space within the dehumidifier housing is available for installing hygroscopic material ingots, maximizing the material capacity and moisture absorption capability of the device.

AI summary
The present invention relates to a split reducible dehumidifier, which includes a hot air supply unit and a hygroscopic ingot that is movably coupled to the air outlet of the hot air supply unit in a detachable manner to perform moisture absorption reduction treatment. The hygroscopic ingot includes a hygroscopic ingot body. The hygroscopic ingot is made by pressing and solidifying porous hygroscopic materials into an ingot-shaped structure with hygroscopic efficiency. The dehumidifier is constructed so as not to require a shell to accommodate the hygroscopic materials. The hygroscopic materials are formed into channels evenly distributed in the deep interior of the hygroscopic ingot body, forming ventilation paths that do not require the installation of air ducts, so that the hot air generated by the hot air supply unit flows through multiple channels, and is evenly distributed to all corners of the inside of the hygroscopic ingot body.
