Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotational structure is added to enable angle adjustment, then viewing angle versatility is improved, but device complexity increases
Solution Approach 1:
The rotational structure is divided into multiple independent components: rotating ring, cam ring, center plate, rear plate, and elastic members. Each component has a specific function, and they work together through modular association. This segmentation allows for easier manufacturing, assembly, and maintenance while achieving the complex rotational adjustment function.
Solution Approach 2:
The patent employs a nested arrangement where the rotating ring, cam ring, and center plate are concentrically positioned around a common rotation axis. The elastic members are disposed between these nested rings, creating a compact layered structure. This nesting reduces the overall footprint and structural complexity while enabling smooth rotational movement.
2Reliability
If frictional contact and elastic members are used for controlled movement, then rotational stability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes elastic members (springs) that change their force parameters based on compression or extension. These elastic members provide a variable restoring force that maintains rotational stability at different angles. The frictional contact parameters are also optimized to provide sufficient holding force while allowing smooth adjustment, reducing the need for extremely tight manufacturing tolerances.
