Solution Overview
Problem
Existing package forming apparatuses for pourable food products face challenges in improving efficiency and maintenance accessibility, particularly in transitioning between operational and idle configurations.
Innovation Solution
A package forming apparatus with a first and second operative unit, each comprising operative devices and conveyor devices, that are rotatable about a common axis to facilitate manipulation of packaging tubes and allow for easy maintenance by switching between operative and idle configurations, enabling efficient package formation and maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the package forming apparatus uses a fixed operational configuration to ensure manufacturing precision, then package formation accuracy is maintained, but maintenance accessibility deteriorates
Solution Approach 1:
The patent implements a rotatable support structure that allows the package forming apparatus to switch between an operational configuration (for accurate package formation) and a maintenance configuration (where the support rotates to provide accessibility to components). This dynamic reconfiguration resolves the contradiction by making the system adaptable to different operational states.
Solution Approach 2:
The support structure is divided into separable components that can be independently positioned. The rotatable support allows different sections of the apparatus to be accessed separately during maintenance while maintaining the complete operational configuration during package formation, enabling segmented access without compromising overall precision.
2Area of stationary object
If the package forming apparatus maintains a compact operational structure to reduce space occupation, then footprint is minimized, but maintenance accessibility worsens
Solution Approach 1:
The rotatable support structure enables the apparatus to maintain a compact footprint during operational phases while dynamically reconfiguring during maintenance phases. The support rotates to extend component accessibility without permanently increasing the occupied space, resolving the contradiction between compactness and accessibility.
3Reliability
If the package forming apparatus uses a rigid fixed structure to ensure operational stability, then manufacturing reliability is improved, but adaptability to maintenance needs deteriorates
Solution Approach 1:
The patent employs a rotatable support that provides rigid stability during package formation operations while enabling adaptive reconfiguration for maintenance activities. The controlled rotation mechanism maintains operational reliability while introducing the flexibility needed for different maintenance scenarios.
Solution Approach 2:
The rotatable support structure serves multiple functions: it provides stable support during operational phases and enables maintenance access during service phases. This multi-functionality allows a single structure to meet both operational reliability requirements and maintenance adaptability needs.
