The air sterilizer and air cleaning device incorporate a case module with a hollow structure to accommodate the ultraviolet sterilizer module, featuring a case fixing structure with hooks and hook fixing grooves for secure assembly, and an anti-rotation unit to prevent rotation and ensure stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ultraviolet sterilizer module is securely fixed using traditional fastening methods, then the reliability of sterilization is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The case module is divided into separate components (case body and case fixing structure) that can be independently manufactured and assembled. The case fixing structure includes multiple hooks that can be selectively engaged with corresponding grooves on the ultraviolet sterilizer module, providing secure fixation without requiring complex fastening mechanisms.
Solution Approach 2:
The case fixing structure is designed to be inserted into and nested within the case module, with hooks that engage into grooves on the ultraviolet sterilizer module. This nested configuration allows the fixing structure to be compactly stored within the case assembly and provides reliable mechanical engagement through the hook-groove interface.
2Ease of manufacture
If the case module structure is simplified for easy assembly, then the ease of manufacture is improved, but the positioning precision and stability of the ultraviolet sterilizer module deteriorate
Solution Approach 1:
The hooks on the case fixing structure and the corresponding grooves on the ultraviolet sterilizer module are designed with asymmetric geometries that provide directional guidance during assembly. This asymmetric design ensures that the module can only be installed in the correct orientation, automatically achieving precise positioning without requiring complex alignment procedures or additional positioning features.
Solution Approach 2:
The case fixing structure is pre-configured with hooks in specific positions and orientations before assembly. These pre-positioned hooks guide the ultraviolet sterilizer module into the correct position during insertion, ensuring accurate positioning is achieved automatically as part of the simple insertion operation, without requiring subsequent adjustment or alignment steps.
3Reliability
If the case module provides comprehensive accommodation for the ultraviolet sterilizer module, then the sterilization effectiveness is improved, but the device complexity increases
Solution Approach 1:
The case module is designed as a multi-functional housing that simultaneously provides structural support, accommodates the ultraviolet sterilizer module, and integrates the case fixing structure for secure assembly. This universal design consolidates multiple functions into a single integrated component system, avoiding the need for separate structural elements and reducing overall device complexity while ensuring comprehensive module accommodation for effective sterilization.
