Solution Overview

Problem

Horizontal freezers require manual emptying, which is inefficient due to the large depth of freezing plates, necessitating long travel lengths for pushing tools, leading to space consumption and wear issues.

Innovation Solution

The use of transverse linear chain actuators with chain wheels positioned proximate to the overhang, supported by skis that strike the ground, and a sliding beam mechanism for efficient emptying and filling, allowing the chain actuators to switch between extended and collapsed configurations with synchronous motor control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the pushing tool has a long travel length to empty the freezing plate completely, then the emptying function is improved, but the space consumption increases and wear is exacerbated

Engineering Contradiction:
Improveemptying functionVSAvoidspace consumption
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The chain actuator is designed to dynamically switch between extended and collapsed configurations. During emptying operations, the actuator extends to provide the necessary long travel length for the pushing tool to reach the bottom of the freezing plate. When not in use, the actuator collapses to a compact size, minimizing space consumption and avoiding wear from prolonged exposure. This dynamic transformation allows the system to have both the functionality of a long-reach tool and the space efficiency of a compact storage solution.

Inventive Principle:
Principle #15Dynamics

2Productivity

If the chain actuator is positioned in an extended configuration for emptying, then the emptying capability is improved, but the wear on chain links increases due to overloading

Engineering Contradiction:
Improveemptying capabilityVSAvoidwear on chain links
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The chain actuator dynamically adjusts its configuration based on operational needs. During emptying operations when long reach is required, the actuator is in extended configuration and bears the loading forces. When retracted to collapsed configuration for storage or transition phases, the actuator is not subjected to operational loads. This dynamic usage pattern ensures that the chain links experience wear only during necessary operational periods rather than continuous exposure, significantly extending component life and improving reliability.

Inventive Principle:
Principle #15Dynamics

3Volume of moving object

If manual emptying is performed using a rod or sliding blocks, then the space requirement is reduced, but the productivity and efficiency decrease

Engineering Contradiction:
Improvespace requirementVSAvoidemptying efficiency
Core Design Contradiction:
Volume of moving objectVSProductivity

Solution Approach 1:

The chain actuator with sliding beam is designed as an automated self-service system for emptying freezing plates. The actuator automatically extends to push frozen items off the plate, and the sliding beam automatically collects and transports the items to a discharge location. This eliminates the need for manual intervention with rods or blocks, significantly improving productivity and efficiency while maintaining a compact footprint through the collapsed configuration capability of the actuator.

Inventive Principle:
Principle #25Self-service
