Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lens holders in optical manufacturing machines are not precise due to a non-smooth surface, which causes lenses to deviate from their predetermined positions, limiting machining precision.
Innovation Solution
A lens holder design featuring a lens holding platform, a base, at least one resilient element, and three platform supporting members aligned on different axes, with an adjustable platform supporting member to adjust the gradient of the lens holding platform relative to the base, ensuring precise alignment of lenses for optimal light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional lens holder with a non-smooth surface is used, then the structure is simple and easy to manufacture, but the lens positioning precision deteriorates causing deviation from predetermined positions
Solution Approach 1:
The lens holder is divided into multiple functional components: a base, a platform with a smooth upper surface for lens placement, and multiple supporting members connecting them. This segmentation allows the platform to provide high positioning precision while the base and supporting members handle structural support, resolving the contradiction between precision and complexity.
Solution Approach 2:
A resilient element is introduced as an intermediary component between the base and the platform. This resilient element absorbs manufacturing imperfections and surface irregularities, providing a stable, smooth platform surface that ensures precise lens positioning even when the base has a non-smooth surface, thus improving positioning precision without requiring the entire structure to be highly complex.
2Manufacturing precision
If the lens holder surface is not smooth, then manufacturing is easier, but the lens alignment accuracy deteriorates limiting machining precision
Solution Approach 1:
The lens holder separates the manufacturing requirements of different components: the base can be manufactured with standard tolerances (easier manufacturing), while the platform is specifically designed with a smooth upper surface (high precision requirement). This segmentation allows each component to be manufactured according to its specific requirements, improving overall machining precision without uniformly increasing manufacturing difficulty.
Solution Approach 2:
The resilient element acts as a mediator that compensates for surface irregularities in the base. It provides a stable, smooth interface for the platform, ensuring that lenses can be positioned with high accuracy even when the base surface is not perfectly smooth, thus achieving high machining precision without requiring the entire structure to be manufactured with high precision.
3Adaptability or versatility
If fixed platform supporting members are used, then the structure is stable, but the ability to adjust lens alignment deteriorates
Solution Approach 1:
One of the platform supporting members is designed as an adjustable member that can be modified in length or position. This dynamic feature allows the lens alignment to be adjusted during setup or operation, providing adaptability for different lens positions while the other fixed supporting members maintain overall structural stability, thus resolving the contradiction between stability and adjustability.
