Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a driving mechanism for optical components is designed to be compact and integrated into modern electronic devices, then the device can achieve higher portability and thinner profile, but the stability and security of the optical component movement may be compromised
Solution Approach 1:
The driving mechanism is segmented into multiple independent components: a first driving assembly for moving the optical component along a first axis, and a limiting assembly with a second driving assembly for rotating the optical component around a second axis. This segmentation allows each subsystem to be optimized independently, maintaining compact size while ensuring stable, controlled movement through specialized functions for each degree of freedom.
Solution Approach 2:
A movable portion acts as an intermediary component that connects the optical component to the driving assemblies. This intermediary structure receives driving forces from both the first and second driving assemblies and transmits them to the optical component, enabling precise control of the optical component's position and orientation while maintaining a compact overall structure.
2Adaptability or versatility
If the optical component is made movable to enable image-capturing and video-recording functions, then the device gains functional versatility, but the durability and privacy security are reduced due to potential unauthorized access or damage
Solution Approach 1:
The limiting assembly is configured to preemptively prevent harmful actions by restricting the optical component's movement to predetermined safe ranges. The first locking structure and second locking structure establish mechanical boundaries that block unauthorized access and prevent impact damage before such harmful events can occur, while still allowing legitimate image-capturing and video-recording operations.
Solution Approach 2:
The system dynamically adjusts the optical component's degrees of freedom based on operational requirements. During normal operation, the optical component can move along the first axis for imaging functions. When impact or unauthorized access is detected or anticipated, the limiting assembly engages to restrict movement, providing adaptive protection while maintaining functional versatility during legitimate use.
3Reliability
If a limiting assembly is added to restrict the range of motion of the optical component, then the durability and privacy are improved, but the device complexity increases
Solution Approach 1:
The limiting assembly is merged with the driving mechanism as an integrated subsystem rather than a separate add-on. The first locking structure and second locking structure are combined within the same movable portion, and both locking functions operate simultaneously through coordinated movement of the limiting assembly. This merging approach reduces overall device complexity compared to having separate limiting and driving systems.
Solution Approach 2:
The movable portion serves multiple functions: it acts as a connector between the optical component and driving assemblies, provides the rotating limiting function through the first locking structure, and enables the reflective limiting function through the second locking structure. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity while achieving comprehensive protection.
