Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional steam cooking oven arrangements are complex to handle due to rigid water drain conduits and valves, requiring additional tools and increasing the risk of leakage and damage during water removal.
Innovation Solution
A flexible water drain pipe that can be easily moved between a rest and working position, integrated with a user-friendly water drain valve, eliminating the need for assembly operations and reducing the risk of wetting the oven by allowing straightforward water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid water drain conduit and separate water drain valve are used, then the structural strength and stability are improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The water drain valve is integrated as an integral end part of the flexible pipe, merging the valve function directly into the conduit structure. This eliminates separate valve components and assembly operations, reducing device complexity while maintaining the drainage function.
Solution Approach 2:
The rigid water drain conduit is replaced with a flexible pipe that can move between rest and working positions. This dynamic flexibility simplifies the draining operation by allowing the pipe to be easily positioned and manipulated, reducing the complexity of assembly and operation.
2Stability of the object's composition
If a rigid water drain conduit and separate water drain valve are used, then the structural stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The flexible pipe can be easily moved between a rest position (accommodated inside the cooking oven) and a working position (extended outward for draining). This dynamic positioning capability greatly simplifies the draining operation, allowing users to easily access and operate the water drain valve without complex assembly steps.
Solution Approach 2:
By integrating the water drain valve as an integral end part of the flexible pipe, the system reduces the number of separate components that need to be handled. Users only need to manipulate the flexible pipe itself, improving ease of operation while maintaining structural stability through the integrated design.
3Reliability
If assembly operations are required for water drainage, then the reliability is improved, but the ease of operation and productivity deteriorate
Solution Approach 1:
The flexible pipe is pre-configured with the water drain valve as an integral end part, so that the drainage system is ready for immediate use. Users simply need to position the flexible pipe and open the valve without any assembly operations, improving ease of operation while maintaining reliability through the pre-integrated design.
4Device complexity
If the water drain valve is integrated as an integral end part of the flexible pipe, then the device complexity is reduced, but the manufacturing precision requirements may increase
Solution Approach 1:
The water drain valve is formed as an integral end part of the flexible pipe, merging two components into one. This reduces device complexity by eliminating separate valve assemblies and connections, while the manufacturing precision is managed through integrated molding or forming processes that create the valve structure as part of the pipe fabrication.
