Solution Overview
Problem
Conventional megapixel multi-focus lens manufacturing apparatuses have low productivity due to manual processes, high defective product rates, and require separation of electrical and mechanical components, which complicates operation and reduces efficiency.
Innovation Solution
An automated apparatus with a loading means, compression-forming means, and discharge means, where the compression-forming process includes preheating, compressing, and cooling units within a nitrogen-filled forming chamber, and a position moving means that prevents heat dissipation holes from being closed, ensuring precise adjustment and efficient heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual processes are used in lens manufacturing, then operation flexibility is maintained, but productivity is low and defective product rate is high
Solution Approach 1:
The manufacturing system is divided into distinct automated modules: a loading means with conveyor for supplying mold bodies, a compression-forming means with preheating/compressing/cooling units, and a discharge means. Each module performs a specific function automatically, eliminating manual operations while maintaining process flexibility through programmable control.
2Device complexity
If electrical control parts are separated from mechanical parts, then maintenance accessibility is improved, but device complexity increases and operation becomes more complicated
Solution Approach 1:
The patent integrates electrical control components within the cabinet housing the mechanical compression-forming system. The control unit, heating elements, compressing mechanism, and cooling systems are combined in a unified structure, reducing overall system complexity while simplifying operation through centralized control interfaces.
3Measurement precision
If the carrying arm contacts the mold body surface, then positioning accuracy is improved, but heat dissipation holes become closed reducing lens formation ability
Solution Approach 1:
The carrying arm is designed with a specific contact geometry that localizes pressure to a linear edge rather than a surface contact. This localized contact approach maintains positioning accuracy while preserving the heat dissipation holes in the mold body surface, ensuring both precise positioning and thermal management functionality.
4Power
If high heat is generated in the forming chamber, then compression-forming efficiency is improved, but heat radiation outside increases affecting worker safety and productivity
Solution Approach 1:
The patent employs a heat blocking plate positioned on the front surface of the forming chamber to intercept and block heat radiation. This converts the harmful heat radiation into a controlled thermal management issue, allowing the forming chamber to maintain high temperatures for efficient compression-forming while preventing excessive heat from radiating outward to affect worker safety and productivity.

AI summary
Disclosed herein is an apparatus for manufacturing a megapixel multi-focus lens. The lens manufacturing apparatus of the present invention includes a loading means for supplying a mold body, in which a blank, interposed between upper and lower molds, is placed, to a forming position, a compression-forming means, which preheats, compresses and cools the supplied mold body such that the blank is formed into a multi-focus lens having an aspherical surface, and a discharge means, which discharges the multi-focus lens formed by the compression-forming means. Therefore, processes from loading to discharging can be automated, so that the productivity of the apparatus for manufacturing the multi-focus lens can be markedly enhanced. Furthermore, because the lens manufacturing apparatus is covered with a cabinet, a superior appearance thereof is ensured. In addition, because various electric components for controlling the compression-forming means are provided in the cabinet, it is not necessary to separately install electrical control parts for mechanical parts.
