Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottom mould locking mechanisms in bottle blowing machines require multiple driving mechanisms, leading to increased energy consumption and bulkiness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple driving mechanisms are used for bottom mould locking, then the locking function is reliable, but energy consumption increases and device volume increases
Solution Approach 1:
The patent combines the elevating mechanism and positioning mechanism into a single integrated system driven by one power source. The rotation shaft simultaneously drives the cam mechanism for elevating the bottom mould and the swing member for positioning, eliminating the need for separate driving mechanisms and reducing overall energy consumption.
Solution Approach 2:
The single power source is designed to perform multiple functions: it drives both the elevating action (through the cam and sliding part) and the positioning action (through the swing member and sliding block). This multi-functional design reduces the total number of components and energy requirements while maintaining reliable locking functionality.
2Reliability
If multiple driving mechanisms are used for bottom mould locking, then the locking function is reliable, but device volume increases
Solution Approach 1:
The patent merges the elevating and positioning mechanisms into a single compact assembly. The rotation shaft, cam, sliding part, swing member, and sliding block are integrated into one coordinated system that occupies significantly less space than three separate driving mechanisms would require.
Solution Approach 2:
The design nests components within each other: the sliding part is inserted into the cam, the swing member rotates around the rotation shaft, and the sliding block moves within the guide rail. This nested arrangement maximizes space utilization and minimizes the overall volume of the mechanism.
3Ease of operation
If three driving mechanisms are used, then the bottom mould can be elevated and positioned, but the device becomes bulky and energy consumption increases
Solution Approach 1:
The single power source is designed with universal capability to perform both elevating and positioning functions. The rotation shaft drives the cam mechanism for elevating the bottom mould while simultaneously driving the swing member for positioning, allowing one component to replace three separate driving mechanisms.
Solution Approach 2:
The mechanism uses dynamic elements including the rotating cam that transforms rotational motion into linear elevating motion, and the swinging member that converts rotational motion into linear positioning motion. These dynamic transformations allow a single power source to control multiple functions through coordinated motion.

AI summary
An elevating and unilateral locking linkage for a bottom mould is provided in the invention. The linkage comprises an elevating assembly and a positioning assembly (3). The elevating assembly comprises an elevating rod (12) disposed on the machine frame (2), the bottom mould (1) is mounted on an upper end of the elevating rod (12), and the elevating rod (12) is driven by a driving assembly (4) to elevate. The driving assembly (4) comprises a rotate shaft (5) rotatably connected on the machine frame (2), a cam (6) fixed on the rotation shaft (5) and a sliding part (13) mounted on the elevating rod (12), a first sliding groove (8) is opened on the cam (6), and the sliding part (13) is slidably inserted into the first sliding groove (8). In the course of rotation of the rotation shaft (5), the contact position of the first sliding groove (8) with the sliding part (13) rises or descends. The positioning assembly comprises a sliding block (31), a swing member (35) for driving the movement of the sliding block (31) and a rotation member (7) fixed on the rotation shaft (5) for controlling the swinging of the swing member (35). The linkage has at least two work positions, in the first work position, there is a certain distance between the bottom mould (1) and the machine frame (2), and the sliding block (31) is inserted between the bottom mould (1) and the machine frame (2) and contacts against the bottom mould (1), in the second working position, the sliding block (31) is separated from the bottom mould (1). In the invention, the linkage of bottom mould (1) elevating and positioning is achieved by a power source, this can save energy and reduce the volume of the whole device.
