Solution Overview

Problem

Existing tray sealers require cumbersome and time-consuming manual processes for replacing cutting and sealing modules, especially when dealing with multiple rows of trays, which complicates maintenance and format changes, and poses safety risks due to the need for manual handling of hot modules.

Innovation Solution

The implementation of mechanical engaging means with vertical movement and a template with thermo-insulating handles allows for quick and safe removal and installation of cutting and sealing modules, utilizing a vertical electric plug system that automatically disconnects during module extraction, enabling automated and efficient replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If manual replacement of cutting and sealing modules is used, then maintenance can be performed, but the process is time-consuming and requires wide free space

Engineering Contradiction:
Improvemodule replacementVSAvoidreplacement time
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The module replacement system transitions from static manual handling to dynamic automated movement. The lifting mechanism with vertical guides and electric motors automatically raises and positions modules, while the conveyor system transports them between stations. This dynamic automation eliminates manual labor and significantly reduces replacement time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If manual handling of hot modules is performed, then module replacement is possible, but safety risks due to burns increase

Engineering Contradiction:
Improvemodule replacementVSAvoidburn risk
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual mechanical handling with automated mechanical systems. Electric motors drive the lifting mechanisms and conveyor belts, substituting human operators with automated equipment that can safely handle hot modules without burn risk.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If drawer-like sliding solution is used for module mounting, then module access is facilitated, but wide free space on machine sides is required

Engineering Contradiction:
Improvemodule accessVSAvoidmachine side space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent moves the module access problem from horizontal sliding (requiring side space) to vertical lifting (using overhead space). The lifting mechanisms with vertical guides raise modules upward, and the conveyor system transports them horizontally at elevated positions, eliminating the need for wide free space on machine sides.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If modules are mounted on hooking plate, then format changes are facilitated, but manual connection and disconnection of electrical systems is required

Engineering Contradiction:
Improveformat change capabilityVSAvoidelectrical connection
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

The patent introduces intermediary devices including lifting mechanisms with vertical guides, conveyor belts, and transfer stations. These intermediaries facilitate the replacement process by automatically transporting modules between maintenance and operating positions, eliminating the need for manual handling and wide free space.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The automated lifting and conveyor system performs the module replacement service itself without human intervention. The system automatically raises modules, transports them to transfer stations, and facilitates electrical connection/disconnection, making the system self-sufficient in the replacement process.

Inventive Principle:
Principle #25Self-service
