Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air is fed into an intermediate lateral chamber of the half-molds using a telescopic feed device, then cooling of the molds is achieved, but the construction becomes extremely complicated, bulky, and expensive with painstaking adjustments required
Solution Approach 1:
The patent extracts the cooling function from the complex telescopic feed device and integrates it directly into the mold structure through cooling channels formed in the half-molds themselves. The cooling air is fed directly to the mold cavities through simplified openings in the bed, eliminating the need for intermediate chambers and telescopic mechanisms.
Solution Approach 2:
The half-molds serve multiple functions: they form the product cavities and simultaneously contain integrated cooling channels. The bed structure also serves dual purposes as both support and air distribution medium, with openings that facilitate cooling air flow to multiple molds simultaneously.
2Temperature
If air is fed upwards through an opening underneath the molds, then cooling is provided, but the cooling is not thorough or continuous
Solution Approach 1:
The cooling air is directed locally and precisely to specific regions of the molds through openings in the bed that align with the mold cavities. The cooling channels within the half-molds ensure that air reaches all critical cooling zones uniformly, providing thorough and continuous cooling throughout the mold structure.
3Temperature
If complex airtight sealing is implemented for telescopic feed devices, then cooling function is achieved, but production cost and adjustment complexity increase significantly
Solution Approach 1:
The patent eliminates the need for complex airtight sealing mechanisms by removing the telescopic feed device entirely. Instead, cooling air is fed through fixed openings in the bed directly to the mold cavities, with cooling channels integrated into the half-molds, thereby eliminating sealing requirements and associated costs.

AI summary
In a glassware molding machine (1), the half-molds (5) of a mold (3) are moved between an open position and a closed position and cooled by an actuating and cooling assembly (12) having a fixed supporting structure (13) and, for each half-mold (5), a respective supporting and actuating arm (15) fitted to the relative half-mold (5) and hinged to the fixed supporting structure (13) to rotate about a fixed hinge axis (25a); each supporting arm (15) internally defining a chamber (25) communicating with a ring of cooling conduits (10) formed through the half-molds (5), and the chamber having an inlet (30) formed through an outer lateral wall (31) of the supporting arm (15) to receive cooling air from a compressed-air tank (39) of the machine (1).
