Solution Overview

Problem

Conventional bottle blowing machines are complex and bulky, making them inconvenient to operate and costly, with existing mechanisms requiring multiple components and complex interactions for mould opening, elevating, and locking.

Innovation Solution

A simplified bottle blowing machine design where three assemblies (mould opening and closing, elevating, and locking) are driven simultaneously by a single rotation shaft, utilizing a fixed and moving mould plate system with a guiding groove and sliding block for vertical movement, and a locking mechanism with a connecting shaft and locking pin for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate mechanisms are used for mould opening, elevating, and locking, then each function can be performed independently, but the device complexity increases and the machine becomes bulky

Engineering Contradiction:
Improvefunctional independenceVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines three separate mechanisms (mould opening/closing, elevating, and locking) into a single integrated mechanism driven by one rotation shaft. The rotation shaft simultaneously drives the moving mould plate for opening/closing, the elevating rod for vertical movement, and the locking pin for securing the mould, thereby reducing device complexity while maintaining functional independence through proper mechanical design of the drive connections

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple separate mechanisms are used for mould opening, elevating, and locking, then each function can be performed independently, but the machine becomes bulky

Engineering Contradiction:
Improvefunctional independenceVSAvoidmachine size
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

By merging three separate mechanisms into one integrated system driven by a single rotation shaft, the patent significantly reduces the overall machine size and footprint. The compact arrangement of the rotation shaft and its connections to the moving mould plate, elevating rod, and locking pin eliminates the need for multiple separate mechanism assemblies, thereby reducing the volume of the stationary object while maintaining functional independence

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional mechanisms with multiple components are used, then functional requirements are met, but the machine is inconvenient to operate

Engineering Contradiction:
Improvefunctional completenessVSAvoidoperational convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent improves operational convenience by combining multiple functions into a single automated system. One rotation shaft simultaneously controls mould opening/closing, elevating, and locking operations, eliminating the need for manual operation of multiple separate mechanisms. This integration simplifies the operating procedure to a single automated cycle while maintaining complete functional requirements through the coordinated design of the drive mechanism

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated mechanism operates automatically through the rotation shaft's coordinated drive system, which self-regulates the timing and sequence of mould opening, elevating, and locking actions. The mechanism serves itself by using the rotational motion to automatically trigger all necessary operations in the correct sequence, reducing the need for external control or manual intervention and thereby improving ease of operation

Inventive Principle:
Principle #25Self-service

AI summary

A bottle blowing machine is provided in the invention. The bottle blowing machine comprises a machine frame, a mould opening and closing assembly, an elevating assembly, a bottom mould locking assembly and a driving assembly. The mould opening and closing assembly comprises a bottom mould, a fixed mould plate and a moving mould plate. The elevating assembly comprises a protrusion, an elevating rod and a sliding block. A guiding groove is opened on the protrusion, and the sliding block is slidably disposed in the guiding groove. The bottom mould is fixed on the upper end of the elevating rod. The bottom mould locking assembly comprises a rotation member, a swing member and a sliding block slidably disposed on the machine frame. The driving assembly comprises a rotation shaft and a power source for driving the rotation of the rotation shaft. The moving mould plate, the protrusion and the rotation member are fixedly connected with the rotation shaft. When the rotation shaft rotates, the fixed mould plate and the moving mould plate close the mould, the elevating rod drives the bottom mould to rise, and the sliding block slides into between the machine frame and a bottom mould. In the bottle blowing machine of the invention, three assemblies are simultaneously driven by one rotation shaft to move, and the steps of mould closing, elevating and locking are simultaneously performed. Thus, the bottle blowing machine of the invention is simple in structure and convenient in operation, thereby improving the efficiency of the process of bottle blowing.
