Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical elements are driven to move a long distance to achieve zooming and focusing functions, then the optical system can provide more optical qualities and consumer choice, but tilting and deflection problems occur leading to reduced stability
Solution Approach 1:
The optical system is divided into multiple independent movable portions (first movable portion, second movable portion) that can be controlled separately. Each movable portion contains specific optical elements and can be driven independently by dedicated driving assemblies, allowing precise control of each segment's position and orientation to prevent tilting and deflection during long-distance movement.
Solution Approach 2:
Sensing assemblies are integrated into the system to detect the positions and movements of optical elements in real-time. The sensing assemblies provide feedback signals to control units, which adjust the driving assemblies to correct any tilting or deflection, ensuring stable optical performance during zooming and focusing operations.
2Ease of operation
If optical elements move long distances for auto focus and zooming functions, then more image-capturing capabilities are achieved, but precision and stability are reduced due to tilting and deflection
Solution Approach 1:
The system employs multiple driving assemblies that can dynamically adjust the positions of different movable portions independently. The driving assemblies enable precise dynamic control of optical elements during movement, maintaining manufacturing precision even during long-distance travel for auto focus and zooming operations.
Solution Approach 2:
The patent replaces traditional mechanical positioning systems with a more advanced combination of driving assemblies and sensing assemblies. This substitution enables more precise control and compensation for mechanical errors, maintaining high precision during long-distance optical element movement.
3Stability of the object's composition
If multiple movable portions are added to enable precise adjustment of optical elements, then stability and precision are improved, but device complexity increases
Solution Approach 1:
The driving assemblies and sensing assemblies are designed to serve multiple functions. The driving assemblies not only move optical elements but also maintain their positions and correct orientations. The sensing assemblies detect various parameters and provide comprehensive feedback for multiple control purposes, reducing the need for separate dedicated components and thereby managing complexity.
