Solution Overview
Problem
Additive manufacturing devices face challenges in achieving uniform temperature distribution in the raw material container, leading to inconsistencies in the quality and strength of manufactured articles, particularly in open containers exposed to varying temperatures.
Innovation Solution
A temperature homogenization box is integrated into the additive manufacturing device, featuring a channel with a heat source that ensures a homogeneous temperature distribution across the raw material surface, maintaining a temperature difference of no more than 15 degrees Celsius, thereby optimizing the heating process and preventing hot spots.

Engineering Contradiction Analysis
1Ease of operation
If an open raw material container is used to facilitate raw material supply, then raw material supply is simplified, but temperature uniformity deteriorates due to exposure to varying temperature surroundings
Solution Approach 1:
A temperature homogenization box is introduced as an intermediary component between the heat source and the open raw material container. This box receives heat from the heat source and distributes it uniformly across the raw material surface, mediating between the need for open container access and temperature uniformity requirements
Solution Approach 2:
The heating system is segmented into distinct functional zones: a heat source region, a temperature homogenization box with internal channels for heat distribution, and the raw material container. This segmentation allows each component to perform its specific function optimally while working together to achieve overall temperature uniformity
2Temperature
If a heat source is added to achieve uniform temperature distribution, then temperature uniformity is improved, but device complexity increases
Solution Approach 1:
The temperature homogenization box merges multiple functions into a single component: it serves as both a heat distribution channel and a temperature control mechanism. The box integrates the heat source interface, heat distribution pathways, and raw material heating function into one unified structure
Solution Approach 2:
The temperature homogenization box performs multiple functions simultaneously: it distributes heat uniformly, maintains temperature control, protects the raw material container from direct heat exposure, and facilitates even heating across the entire raw material surface without requiring separate systems for each function

Implementation Method 1
The heat generated by the heat source is transferred to the cross-sectional area delimited by the second wall edges in such a way that a homogeneous temperature distribution in this cross-sectional area is obtained
