Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical systems face challenges in achieving coaxial alignment of optical elements due to manufacturing tolerances, leading to reduced yield rates and increased manufacturing costs.
Innovation Solution
An adjusting device comprising three movable elements along distinct axes (first, second, and third axes) is used to precisely adjust the center of an optical device, ensuring coaxial alignment with optical elements, utilizing adjustment screws and cylindrical elements to facilitate horizontal and vertical adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional adjustment methods are used to achieve coaxial alignment, then manufacturing precision may be maintained, but adjustment range is limited and operation becomes complex
Solution Approach 1:
The adjustment device is segmented into three independent adjusting elements, each responsible for adjusting the optical device along a specific axis. This segmentation allows each element to be operated independently, simplifying the adjustment process while achieving precise coaxial alignment through coordinated movement along multiple axes
Solution Approach 2:
The adjusting elements act as intermediaries between the operator and the optical device. By introducing these intermediary adjustment mechanisms, the system enables precise control of the optical device's position without requiring direct manipulation, thus improving ease of operation while maintaining manufacturing precision
2Adaptability or versatility
If multiple adjusting elements are added to increase adjustment range, then adjustment flexibility is improved, but device complexity increases
Solution Approach 1:
Each adjusting element is designed to perform multiple functions: adjusting the optical device along its designated axis, providing mechanical support, and enabling both horizontal and vertical adjustments when combined with other elements. This multi-functionality increases adjustment range without proportionally increasing device complexity
Solution Approach 2:
The adjustment device transitions from single-axis to multi-axis adjustment by introducing adjusting elements along different axes. This dimensional expansion allows the optical device to be positioned in three-dimensional space, significantly increasing adjustment range while maintaining a relatively simple structure through the use of orthogonal axis arrangements
3Productivity
If precise adjustment mechanisms are implemented to improve yield rate, then manufacturing precision is improved, but manufacturing cost increases
Solution Approach 1:
The adjusting elements are designed to be self-aligning through their geometric relationships with the optical device. The adjustment mechanism utilizes the inherent geometry of the optical device center and axis intersections to automatically guide the adjustment process, reducing the need for complex control systems and expensive manufacturing processes while improving yield rate
