Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the power supply container is designed to contain the battery replaceably and have the chemical receptacle replaceably mounted therewith, then the battery and chemical receptacle can be replaced for continued use, but the structure becomes complicated and costly
Solution Approach 1:
The battery container and chemical receptacle mounting structure are merged into a single integrated body. The battery is mounted directly in the apparatus body with the chemical receptacle positioned adjacent to it, eliminating the need for a separate power supply container. This integration maintains replaceability of both components while significantly simplifying the overall structure and reducing manufacturing costs.
2Quantity of substance
If the chemical receptacle is designed to fill a large number of particulate chemical impregnated bodies in a porous receptacle body, then the chemical storage capacity is increased, but the volume and thickness of the receptacle must be large
Solution Approach 1:
The chemical receptacle employs a porous receptacle body that efficiently stores and releases volatile chemicals through its porous structure. This porous material allows for high chemical storage capacity within a compact volume, as the porous structure provides large surface area for chemical impregnation without requiring excessive thickness or volume. The porous body enables effective chemical diffusion while maintaining a compact form factor.
3Quantity of substance
If the apparatus body is made large in thickness to accommodate the chemical receptacle, then the chemical storage capacity is sufficient, but the apparatus becomes cumbersome and difficult to handle
Solution Approach 1:
The porous receptacle body provides high chemical storage capacity through its porous structure, which allows efficient chemical impregnation and release without requiring large volume. This enables sufficient chemical storage in a compact, thin-profile apparatus body that remains easy to handle and wear, eliminating the need for excessive thickness while maintaining adequate chemical capacity for extended use.

AI summary
A blower type chemical diffusing apparatus is small in thickness, simple in structure and reduced in cost structurally. This apparatus allows the chemical and battery to be exchanged readily and to facilitate electrically connecting battery to the motor in the blower. The apparatus casing comprises a first and a second side casing counterpart hinged together to allow its opening and closure. The apparatus also includes a blower with a motor and fan mounted in the first casing body. A chemical cartridge is disposed between the blower and the second casing body. The cartridge contains a chemical impregnated body that comprises a carrier in the form of a sheet impregnated with chemical. Also provided in the first casing body is a battery accommodating recess in which dry cells may removably be accepted to drive the motor and thereby to rotate the fan. Air is thus forced to flow through the chemical cartridge.
