Solution Overview
Problem
Existing polishing devices for non-rotationally symmetrical optical lenses face challenges in mobility and service life due to limitations in adapting to complex lens surfaces and wear resistance during zone polishing.
Innovation Solution
A polishing device with a tilting base part connected to a rotary spindle shaft and a flexible fluid connection for polishing compound supply, along with a separate bearing part made from a different material for improved mobility and wear resistance, allows the polishing pad to tilt freely and maintain effective polishing compound delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tilting base part is used for zone polishing of non-rotationally symmetrical lenses, then adaptability to complex lens surfaces is improved, but mobility is reduced due to the fixed connection to the polishing spindle
Solution Approach 1:
The base part is divided into two functional segments: a tiltable base part for adapting to complex lens surfaces and a rotary leadthrough that remains stationary on the spindle shaft. This segmentation allows the base part to tilt for adaptability while the leadthrough stays fixed, preventing mobility restrictions.
Solution Approach 2:
A flexible fluid connection acts as an intermediary between the stationary rotary leadthrough and the tilting base part. This flexible connection transmits polishing compound while accommodating the tilting motion, thereby maintaining mobility without compromising the adaptability of the base part.
2Ease of operation
If the base part is made from nonhard materials such as rubber to ensure a clamping seat, then ease of clamping is improved, but service life is reduced due to wear
Solution Approach 1:
The base part is constructed as a composite structure combining a hard, wear-resistant outer layer with a softer, elastic inner layer. The hard outer layer provides durability and resistance to wear from polishing compound, extending service life, while the elastic inner layer maintains the clamping seat functionality for easy pad attachment and removal.
