Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ultraviolet lamp is always set on the mobile phone to enable sterilization, then the sterilization function is available at any time, but the usage frequency becomes too low and the load becomes excessive
Solution Approach 1:
The ultraviolet sterilization function is segmented from the main mobile phone body and placed in a detachable module. This allows the sterilization function to be activated only when needed, reducing the overall device load while maintaining availability. The module can be attached to the phone when sterilization is required and removed when not needed.
Solution Approach 2:
The ultraviolet module is designed with dynamic attachment capability, allowing it to be connected or disconnected from the mobile phone based on usage needs. This dynamic configuration enables the system to adapt between high-availability sterilization mode (module attached) and low-load mode (module removed), resolving the contradiction between continuous availability and excessive load.
2Adaptability or versatility
If the ultraviolet lamp is provided directly at the terminal body, then the sterilization function is integrated, but the frequency of use is too low and the load is excessive
Solution Approach 1:
The sterilization function is segmented into a separate detachable module rather than being permanently integrated into the mobile phone body. This segmentation allows the function to be activated only when needed, reducing the overall device load while maintaining adaptability. The module can be attached to the phone when sterilization is required and removed when not needed.
Solution Approach 2:
The detachable ultraviolet module serves multiple functions: it provides sterilization capability when attached to the mobile phone, and can be used independently as a portable sterilization device. This multi-functionality enhances adaptability while avoiding the excessive load of having the full sterilization system permanently integrated into the phone.
3Reliability
If the ultraviolet lamp is set for irradiation, then sterilization can be performed, but direct UV exposure poses a risk of human damage
Solution Approach 1:
The system incorporates sensors (light sensors, proximity sensors, camera-based detection) that provide real-time feedback about the presence of people or objects in the sterilization area. When such feedback is detected, the system automatically stops or adjusts the ultraviolet irradiation, preventing human exposure while maintaining sterilization effectiveness when safe.
Solution Approach 2:
The system performs preliminary detection of human presence using sensors before activating the ultraviolet lamp. This preliminary anti-action prevents harmful UV exposure by stopping the sterilization process in advance when people are detected, while still allowing effective sterilization when the area is clear.
4Reliability
If the ultraviolet lamp irradiates the entire area, then complete sterilization is achieved, but the usage scenario is not applied to the personal area
Solution Approach 1:
The ultraviolet module provides localized sterilization rather than full-area irradiation. The light source is positioned to target specific personal items or areas (such as a handbag, wallet, or small surface) where sterilization is most needed. This local quality approach makes the system practical for personal use while still achieving complete sterilization of the targeted area.
Solution Approach 2:
Instead of irradiating the entire environment, the system applies partial action by focusing UV light only on the specific personal items or surfaces that need sterilization. This partial approach is more suitable for personal areas and portable use, achieving sufficient sterilization effectiveness without the complexity of full-area irradiation.

AI summary
Disclosed are a communication device and a disinfection and sterilization method. A terminal body is detachably and electrically connected to an ultraviolet sterilization apparatus or is in wireless communication connection with same, and via the terminal body, the ultraviolet sterilization apparatus is controlled to switch on to perform ultraviolet sterilization at a predetermined site, thereby ensuring that the ultraviolet sterilization apparatus can perform sterilization at a specific site within a small range at any time, which is simple and convenient; in addition, the ultraviolet sterilization apparatus can be completely separated from the terminal body when not in use, thereby preventing the terminal body from being excessively loaded due to the ultraviolet sterilization apparatus continuing to be arranged at the terminal body.
