Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glass processing mold is used for wafer-level lenses, then lenses can be produced by thermoforming, but the service life of the mold is limited
Solution Approach 1:
The mold is divided into multiple independent components including a lower mold, upper mold, support portions, and fixing portions. This segmentation allows each component to be optimized independently and replaced or maintained separately, extending the overall service life of the mold system.
Solution Approach 2:
The upper mold is designed as a movable mold that can be connected and disconnected from the lower mold, while the support portions provide dynamic structural support. This dynamic design allows for easier maintenance and replacement of wear-prone components, thereby extending service life.
2Productivity
If a traditional glass processing mold is used, then molding can be performed, but molding efficiency is limited
Solution Approach 1:
The support portions are pre-configured in the lower mold at predetermined positions, and the fixing portions are pre-designed on both molds. This preliminary arrangement of structural elements enables faster mold assembly and disassembly, significantly improving molding efficiency and reducing cycle time.
Solution Approach 2:
By segmenting the mold into movable and fixed components with pre-defined interfaces, the molding process can be optimized for rapid cycling. The segmented design allows for quicker mold opening and closing operations, thereby increasing productivity.
3Manufacturing precision
If a simple mold structure is used, then manufacturing is easier, but molding precision deteriorates
Solution Approach 1:
The support portions are strategically positioned at specific locations where structural support is most needed to maintain molding precision. The fixing portions are located at peripheries where they provide optimal constraint without interfering with the molding cavity. This localized optimization of structural elements achieves high precision without unnecessary overall complexity.
Solution Approach 2:
The support portions extend from the lower mold toward the upper mold in a vertical dimension, providing three-dimensional structural support. This spatial arrangement enhances molding precision by distributing mechanical loads throughout the mold assembly, achieving high precision with a relatively simple structural design.

AI summary
A molding mold of a glass product includes a lower mold defining a first molding surface and an upper mold defining a second molding surface. The first molding surface is disposed on one side of the lower mold close to the upper mold. The second molding surface is opposite to the first molding surface. The first molding surface includes a first molding portion and a first fixing portion disposed on a periphery of the first molding portion. The second molding surface includes a second molding portion and a second fixing portion disposed on a periphery of the second molding portion. The lower mold includes a support portion extending from the first fixing portion of the lower mold toward the second fixing portion. The support portion abuts against the second fixing portion, so that the first molding portion and the second molding portion form a molding chamber.
