A cooking device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cooking devices with a water-contacting cooking chamber, splattering food and water can unintentionally activate the safety mechanism during cleaning, leading to errors and increased customer complaints and service failures.
Innovation Solution
A safety member with a closed base extending into the cooking chamber and an inlet on its lateral wall prevents splashing water from reaching the safety mechanism, using a delivery pipe to redirect water outside, thus preventing unnecessary activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the safety member has an open end to allow quick water flow to the safety mechanism, then the response speed of the safety mechanism is improved, but water splatter can unintentionally activate the safety mechanism during cleaning
Solution Approach 1:
The safety member has different structural characteristics at different locations: the base is closed to prevent water entry from below, while the upper portion has an opening with inlet and outlet for controlled water flow. This local differentiation allows the safety mechanism to respond quickly to legitimate water flow while preventing false activation from splatter.
Solution Approach 2:
The opening in the safety member acts as an intermediary structure that controls water flow between the cooking chamber and the safety mechanism. The inlet receives water from the cooking chamber, and the outlet directs it to the safety mechanism, filtering out unintended water entry while maintaining rapid response capability.
2Device complexity
If the base of the safety member is open to allow water flow, then the water flow path is simplified, but splashing water enters the safety member and causes errors
Solution Approach 1:
The base of the safety member is closed while the upper portion remains open with controlled inlet and outlet. This local structural differentiation prevents water entry at the base level while maintaining simplified water flow paths through the controlled opening, thus preventing errors without significantly complicating the overall structure.
3Reliability
If the safety member is positioned to monitor water level, then the safety mechanism can detect overflow, but water splatter during cleaning is detected as malfunction
Solution Approach 1:
The opening in the safety member serves as an intermediary that allows controlled water flow for safety monitoring while preventing uncontrolled water entry during cleaning. The inlet and outlet configuration ensures that only intended water flow activates the safety mechanism, not splatter from cleaning operations.
