Push-and-Turn Knob Control for Precise Cooking Time and Heat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking devices require users to adjust heat energy and cooking time using knob-type input units, which can lead to inaccurate and imprecise adjustments, making it difficult to grasp the amount of heat energy supplied and remaining cooking time during the cooking process.
Innovation Solution
A cooking device featuring a push-and-turn knob module with a coupled knob ring that operates in a click or hold manner, allowing for precise adjustment of heat energy and cooking time, along with a display unit for immediate feedback on set values, enabling intuitive and accurate control of various heating modules without the need for replacing control means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a knob-type input unit is used for adjusting heat energy and cooking time, then the device structure is simple, but the adjustment precision and ease of operation deteriorate
Solution Approach 1:
The control input unit is segmented into two distinct components: a knob for coarse adjustment and a knob ring for fine adjustment. This segmentation allows users to perform rough adjustments with the knob and then make precise adjustments with the knob ring, significantly improving ease of operation and adjustment precision without requiring an entirely complex control system.
2Measurement precision
If a knob-type input unit is used for adjusting heat energy and cooking time, then the device structure is simple, but the measurement precision of set values deteriorates
Solution Approach 1:
The control input unit is segmented into two distinct components: a knob for coarse adjustment and a knob ring for fine adjustment. This segmentation allows users to perform rough adjustments with the knob and then make precise adjustments with the knob ring, significantly improving ease of operation and adjustment precision without requiring an entirely complex control system.
3Adaptability or versatility
If separate control means are provided for different heating modules, then each module can be controlled independently, but the device complexity and manufacturing cost increase
Solution Approach 1:
A universal control panel is designed that can accommodate and control multiple types of heating modules (e.g., induction, electric, gas) using the same interface and control mechanisms. This multi-functional control panel eliminates the need for separate control means for each heating module type, reducing device complexity and manufacturing costs while maintaining adaptability across different module types.
