Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the camera unit and infrared radiator are integrated on a shared carrier element, then the device complexity is reduced and ease of manufacture is improved, but the spatial arrangement and optical alignment precision may be compromised
Solution Approach 1:
The patent combines the camera unit and infrared radiator onto a single carrier element, creating an integrated assembly that simplifies manufacturing and installation. The carrier element serves as a common mounting platform that holds both components in fixed spatial relationships, eliminating the need for separate mounting procedures and reducing overall system complexity.
Solution Approach 2:
The carrier element acts as an intermediary component that mediates between the infrared radiator and camera unit. It provides a standardized interface for mounting both components and includes alignment features such as positioning pins or registration marks that ensure precise optical alignment between the infrared light source and camera sensor during assembly.
2Ease of repair
If the infrared radiator is detachably locked on the carrier element, then the ease of repair and component replacement is improved, but the reliability of the connection may be compromised
Solution Approach 1:
The locking device provides a dynamic connection system that transitions between locked and unlocked states. When locked, the connection achieves high stability and reliability for normal operation. When unlocked, the infrared radiator can be easily removed for replacement or maintenance. The mechanism includes engagement features such as bayonet mounts, snap-fit connectors, or threaded fasteners that provide secure mechanical retention during operation.
Solution Approach 2:
The mounting system is segmented into separable components: the carrier element with locking mechanisms and the infrared radiator with corresponding engagement features. This segmentation allows the infrared radiator to be independently removed and replaced without affecting the camera unit or other system components, facilitating easy maintenance and upgrades while maintaining connection reliability when assembled.
3Adaptability or versatility
If multiple locking devices are provided on the carrier element, then the adaptability and modularity of the system is improved, but the device complexity increases
Solution Approach 1:
The locking devices are designed with universal characteristics, using standardized mounting patterns and identical or similar locking mechanisms at multiple positions on the carrier element. This allows the same type of infrared radiator to be mounted in different configurations (single unit, dual units, different orientations) using the same locking device design, providing configuration flexibility without requiring multiple different locking mechanisms.
