VSEngineering Contradiction Analysis

1Productivity

If multiple inner tanks are arranged side by side or stacked in the case, then the drying capacity and productivity are improved, but heat transmission and odor transfer between chambers occur, affecting temperature control and food quality

Engineering Contradiction:
Improvedrying capacityVSAvoidtemperature control
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

A barrier structure is introduced as an intermediary element between adjacent inner tanks. This barrier structure includes an insulating layer made of heat-insulating material that blocks heat transmission between chambers, and a sealing structure that prevents odor transfer. The barrier structure acts as a mediator that allows multiple tanks to coexist while maintaining thermal independence and preventing contamination between chambers.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The interior space of the case is segmented into multiple independent drying chambers by the barrier structure. Each inner tank operates as a separate compartment with independent temperature control, allowing different drying conditions to be maintained in different chambers simultaneously. This segmentation enables multi-cavity operation without compromising individual chamber performance.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If inner tanks are positioned close together to maximize space utilization, then the device compactness is improved, but heat blocking and odor prevention between chambers become insufficient

Engineering Contradiction:
Improvespace utilizationVSAvoidheat transmission and odor transfer
Core Design Contradiction:
Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The barrier structure employs thin film-like sealing structures that extend along the periphery of the barrier, creating an effective seal between adjacent chambers. These flexible sealing elements can adapt to the spatial arrangement of inner tanks while maintaining their blocking function, allowing compact design without compromising separation effectiveness.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The barrier structure serves as a mediating element that enables close positioning of inner tanks while preventing harmful interactions. By placing this intermediate barrier between tanks, the design achieves high space utilization while the barrier's insulating and sealing properties prevent heat transmission and odor transfer even when tanks are positioned adjacently.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present invention relates to the technical field of drying equipment, and particularly to a dryer, including a case, at least two inner tanks and air supply assemblies, where the at least two inner tanks each include a side wall member formed by sequentially connecting at least two side plates into one piece, the at least two inner tanks are each provided with an inner chamber; the two inner tanks are provided side by side or stacked in the case, and side wall members of the two inner tanks are provided at intervals so as to form a barrier structure, where the barrier structure is configured to block heat between the inner chambers of the two inner tanks. In the solutions of the present invention, by forming the barrier structure between the side wall members of two inner tanks, the inner chambers of the two inner tanks can be blocked by the barrier structure, so that heat transmission between the two adjacent inner chambers can be reduced, the influence of influenced temperature and tainted odor between different inner chambers can be reduced and even avoided, and independence of processing food between different inner chambers can be improved, so that users can have better using experience.
