Solution Overview

Problem

Conventional heat treatment systems, such as ovens and proofers, face inefficiencies in energy usage and loading/unloading processes, including missed notifications leading to overheating, temperature drops due to door opening, and time-consuming tray handling.

Innovation Solution

A heat treatment system with a tray holder and elevation apparatus that allows for automated loading and unloading through a base opening, reducing heat loss and incorporating a vacuum pump for energy-efficient baking, and a rack system for accommodating trays, enabling quick and efficient handling of baking goods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the front door is opened for loading or unloading trays, then the loading and unloading process can be performed, but hot air is exchanged with cold air from outside leading to temperature drop and energy inefficiency

Engineering Contradiction:
Improveloading and unloading processVSAvoidenergy efficiency
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The opening is segmented into two separate openings: a first opening in the base part for loading/unloading and a second opening in the upper part for ventilation. This segmentation allows the loading/unloading function to be separated from the main chamber opening, enabling operation without opening the front door and thus preventing heat loss.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A dividing piece is introduced as an intermediary element that can close the first opening when not in use. This dividing piece acts as a mediator between the loading/unloading requirement and the heat preservation requirement, allowing the opening to be closed during operation to prevent energy loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If trays are loaded and unloaded one after the other manually, then the front door can be kept closed most of the time, but the process takes up a lot of time

Engineering Contradiction:
Improveenergy efficiencyVSAvoidloading and unloading speed
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The loading and unloading process is moved from the front horizontal dimension to the base vertical dimension. By providing a first opening in the base part and using an elevation apparatus to move trays vertically, multiple trays can be loaded and unloaded simultaneously or in rapid succession without opening the front door, thus improving productivity while maintaining energy efficiency.

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

3Extent of automation

If a base opening is provided for automated loading and unloading, then loading and unloading can be automated and heat loss reduced, but the system complexity increases

Engineering Contradiction:
Improveautomated loading and unloadingVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The elevation apparatus is designed to automatically move trays between the rack system and the heat treatment chamber without requiring external intervention. The system serves itself by integrating the elevation function directly into the chamber structure, reducing the need for additional complex external mechanisms while achieving automation.

Inventive Principle:
Principle #25Self-service
