Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lens holder devices for optical lenses in processing machines are inefficient in reducing tank size while maintaining treatment quality and preventing swinging movements during conveyor carriage direction changes, which limits the number of lenses that can be immersed simultaneously.
Innovation Solution
A lens holder device with a body extending between two locations, featuring elastic return means and support points to secure lenses without obstructing optical faces, and a hook mechanism to stabilize the device on the conveyor carriage, allowing for reduced tank width and increased lens capacity without compromising treatment quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the tank size is reduced to optimize machine footprint, then the processing machine size is reduced, but the lens loading capacity may be compromised
Solution Approach 1:
The lens holder device is divided into two separate holding locations (first and second locations) positioned at different angular positions relative to the support. This segmentation allows lenses to be held in distributed positions, maximizing the use of available tank space while maintaining adequate spacing for treatment quality.
Solution Approach 2:
The invention utilizes angular positioning in three-dimensional space around the support, rather than simply linear arrangement. By positioning lenses at different angular positions (with specific angular differences specified), the device effectively uses the radial dimension to increase loading capacity within the constrained tank cross-section.
2Stability of the object's composition
If the hook mechanism is added to prevent swinging movements, then the stability during direction changes is improved, but the device complexity increases
Solution Approach 1:
The hook mechanism acts as a counterbalancing element that prevents swinging movements of the lens holder device during direction changes of the conveyor carriage. The hook engages with the support structure to provide stabilizing force counteracting the inertial forces generated during acceleration and deceleration.
3Measurement precision
If the body is positioned outside the volume between the two locations, then optical measurements are not hindered, but the manufacturing complexity increases
Solution Approach 1:
The lens holder device body is segmented into distinct functional zones: the holding locations for lenses and the body structure for support and optical measurements. By positioning the body outside the volume between the two lens locations, the patent ensures that optical measurement paths remain clear while the body provides structural support and mounting functions.
