Shell-Free Blow Mould Mounting for Compact Transforming Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transforming stations for plastic parisons into plastic containers require a large installation space due to the use of blow mould carrier shells, which are often unnecessary and occupy valuable space.
Innovation Solution
The proposed transforming station eliminates the need for mould carrier shells by directly fastening side parts to side part carriers, allowing for a more compact design, and incorporates temperature-controlled side part carriers for efficient temperature management without the need for external coolant connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If blow mould carrier shells are used to retain blow moulds, then stability and support are improved, but installation space increases significantly
Solution Approach 1:
The patent removes the blow mould carrier shells from the system entirely. Instead of using shells to retain the blow moulds, the side part carriers directly support the side parts of the blow moulds without any intermediate shell structure. This extraction of the shell component eliminates the space-consuming intermediate structure while maintaining functional stability through direct fastening mechanisms.
Solution Approach 2:
The patent merges the functions of the carrier shell and the side part carrier into a single integrated structure. The side part carriers directly retain the side parts of the blow moulds, combining the support and retention functions that were previously separated into distinct components (shell + carrier). This merging reduces the overall system footprint while maintaining stability.
2Strength
If mould carrier shells are used, then structural support is improved, but device complexity increases
Solution Approach 1:
The patent extracts and eliminates the intermediate carrier shell component from the system. By removing this component, the overall device complexity is reduced while the necessary structural support functions are maintained through direct fastening of side parts to side part carriers using integrated fastening mechanisms.
3Area of stationary object
If side parts are directly fastened to side part carriers without shells, then installation space is reduced, but ease of manufacture may be affected
Solution Approach 1:
The patent combines the fastening function directly into the side part carrier structure. The side part carriers are designed with integrated fastening mechanisms that directly secure the side parts, merging the retention and fastening functions into a single manufacturing process. This eliminates the need for separate shell assembly steps while maintaining manufacturing feasibility through standardized fastening interfaces.
