Solution Overview

Problem

Automatic dispensing machines for frozen products experience high energy consumption due to direct heat exchange between the storage region and the external environment during product distribution, leading to frequent activation of cooling systems and increased maintenance costs.

Innovation Solution

The automatic dispensing machine incorporates separation means, such as movable flexible panels and a collection board, to isolate the storage region from the dispensing region, minimizing direct heat exchange and reducing energy consumption by maintaining the cold within the storage area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the storage region is left open during product distribution, then products can be easily accessed by users, but direct heat exchange occurs between the storage region and external environment causing high energy consumption

Engineering Contradiction:
ImproveProduct accessibilityVSAvoidEnergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The dispensing machine is divided into two distinct thermal zones: a cold storage region for keeping frozen products and a warmer dispensing region for user interaction. This segmentation prevents direct heat exchange between the storage area and external environment while maintaining easy product access through the automated dispensing mechanism.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A collection board acts as an intermediary element between the storage region and dispensing region. It temporarily holds products during transfer, allowing the storage region to remain closed and isolated thermally while still enabling product distribution to users in the dispensing region.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the storage region is isolated from the dispensing region, then heat exchange is minimized reducing energy consumption, but product distribution becomes more complex

Engineering Contradiction:
ImproveEnergy consumptionVSAvoidDispensing mechanism complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The collection board serves multiple functions: it acts as a thermal barrier separating the storage and dispensing regions, serves as a temporary holding platform for products during transfer, and works in conjunction with the pusher member to automate the dispensing process. This multi-functionality reduces the need for additional complex components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The pusher member is designed to be movable, dynamically pushing products from the storage region onto the collection board and then into the dispensing region. This dynamic mechanism simplifies the overall system by using a single active component to handle product transfer across the thermal boundary.

Inventive Principle:
Principle #15Dynamics

3Temperature

If cooling means are frequently activated to maintain temperature, then storage region temperature is maintained, but maintenance costs increase

Engineering Contradiction:
ImproveStorage region temperatureVSAvoidMaintenance costs
Core Design Contradiction:
TemperatureVSEase of repair

Solution Approach 1:

By segmenting the machine into isolated thermal zones with the collection board acting as a barrier, heat ingress into the storage region is minimized. This reduces the frequency and intensity of cooling activation, thereby lowering energy consumption and reducing wear on cooling components, which in turn decreases maintenance requirements and costs.

Inventive Principle:
Principle #1Segmentation
