Touchscreen Cooking Time Adjustment for Rapid Program Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking devices, such as hot-air ovens and combi-steamers, require cumbersome navigation through cooking programs to extend or reduce cooking time, often leading to operators skipping time adjustments due to time constraints, resulting in suboptimal cooking results.
Innovation Solution
A touch screen interface with dedicated buttons allows for immediate and rapid extension or reduction of cooking time by preset periods, enabling users to adjust the last cooking step in seconds, with options for continuous adjustments and safety limits to prevent overcooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator navigates through the cooking program to adjust cooking time settings, then the cooking time can be extended or reduced, but this process is cumbersome and time-consuming
Solution Approach 1:
The system prepares the cooking time adjustment interface in advance by displaying it automatically during the last cooking step, eliminating the need for users to navigate through menus. The extension/reduction buttons are pre-positioned and immediately accessible, so when the user wants to adjust cooking time, the interface is already ready for interaction without requiring any preliminary navigation steps.
Solution Approach 2:
The cooking time adjustment functionality is extracted from the general cooking program navigation and separated into a dedicated, standalone interface. Instead of requiring users to search through the cooking program settings, the extension and reduction buttons are pulled out as prominent, always-visible controls during the last cooking step, making the adjustment operation independent and immediate.
2Manufacturing precision
If the operator extends or reduces cooking time for a short period, then optimal cooking results can be achieved, but the adjustment process takes more time than the extension itself
Solution Approach 1:
The system prepares the cooking time adjustment interface in advance by displaying it automatically during the last cooking step, eliminating the need for users to navigate through menus. The extension/reduction buttons are pre-positioned and immediately accessible, so when the user wants to adjust cooking time, the interface is already ready for interaction without requiring any preliminary navigation steps.
Solution Approach 2:
The system allows users to skip the entire menu navigation process and go directly to the cooking time adjustment function. By presenting the extension and reduction buttons prominently during the last cooking step, the system enables users to rush through the adjustment process in seconds, making the time investment for adjustment negligible compared to the actual cooking time being adjusted.
3Adaptability or versatility
If the operator uses the menu system to adjust cooking time, then cooking time can be changed, but the complexity of the device increases
Solution Approach 1:
The cooking time adjustment functionality is extracted from the general cooking program navigation and separated into a dedicated, standalone interface. Instead of requiring users to search through the cooking program settings, the extension and reduction buttons are pulled out as prominent, always-visible controls during the last cooking step, making the adjustment operation independent and immediate.
Solution Approach 2:
The touch screen display serves multiple functions: it displays cooking program information, shows the last cooking step details, and simultaneously presents the cooking time extension and reduction controls. By making the display universal and multi-functional, the system avoids adding separate physical buttons or controls, thereby increasing adaptability without proportionally increasing device complexity.
