Light Path Adjustment Mechanism Using Electromagnetic Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light path adjustment mechanisms are bulky, heavy, and occupy significant space, making them difficult to miniaturize and integrate into compact electronic devices.
Innovation Solution
A compact light path adjustment mechanism is designed using a support, carrier, optical plate member, permanent magnet, and electromagnet, where the actuator is disposed on the carrier to generate attractive and repulsive forces, allowing the optical plate member to rotate and tilt, reducing component count and weight while enabling a wide angular range of motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional light path adjustment mechanism is used, then image resolution and picture quality can be improved, but the mechanism becomes bulky, heavy, and occupies significant space
Solution Approach 1:
The patent merges the optical plate member and mount into a single integrally formed component, reducing the number of separate parts. Additionally, the actuator is strategically positioned on only one side of the carrier rather than requiring components on both sides, further consolidating the mechanism and reducing overall volume while maintaining light path adjustment functionality
Solution Approach 2:
The patent replaces conventional mechanical adjustment mechanisms with an electromagnetic actuator system. The actuator uses electromagnetic fields to tilt the optical plate member between different positions, eliminating the need for complex mechanical linkages, gears, or manual adjustment mechanisms, thereby significantly reducing the volume and weight of the overall system
2Measurement precision
If a conventional light path adjustment mechanism is used, then image resolution can be improved, but the weight of the mechanism increases
Solution Approach 1:
The optical plate member and mount are integrally formed as one piece, eliminating the weight of separate components and their connecting hardware. This consolidation reduces the overall weight while maintaining the structural integrity needed for precise light path adjustment
Solution Approach 2:
The electromagnetic actuator replaces heavy mechanical adjustment systems, using electromagnetic fields rather than mechanical forces to achieve the required tilting motion. This substitution dramatically reduces the weight of the moving components while providing sufficient force for precise positioning
3Measurement precision
If a conventional light path adjustment mechanism is used, then image resolution can be improved, but the number of components increases
Solution Approach 1:
The patent combines multiple functions into fewer components: the integrally formed optical plate member and mount perform both optical function and structural support, while the actuator on one side provides bidirectional tilting capability, eliminating the need for separate components on both sides of the carrier
Solution Approach 2:
The single actuator positioned on one side of the carrier serves multiple functions: it tilts the optical plate member in both directions, provides precise angular control for light path adjustment, and eliminates the need for separate actuators or mechanical linkages that would otherwise be required on both sides of the mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a slim and compact mechanism that reduces occupied space, weight, and fabrication costs, while providing a sufficient angular range of rotation for improved image resolution and picture quality in mini-type electronic devices.
