Nested Dual-Action Control Knob for Multifunction Appliance Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliances lack a user-friendly and efficient operating mechanism that can handle multiple functions with a simple and easy-to-implement structure, limiting user convenience and operational complexity.
Innovation Solution
An operating assembly comprising a first and second operating portion, where the second operating portion can move between positions to generate electric signals for different functions, allowing for rotational and pressing actions to control various appliance functions, such as a gas stove's ignition and fire adjustment, by integrating a coupling structure and elastic members for stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional rotary knob is used for operation, then the structure is simple, but the functional versatility is limited
Solution Approach 1:
The operating assembly is divided into two distinct operating portions: a first operating portion for rotational operation and a second operating portion for pressing operation. Each portion can independently generate different electric signals, allowing a single assembly to provide multiple functions without requiring multiple separate controls, thus resolving the contradiction between versatility and complexity.
Solution Approach 2:
The operating assembly is designed as a universal control mechanism that can perform multiple functions through its two operating portions. The first operating portion can rotate to generate different signals for different functions, and the second operating portion can be pressed to generate another set of signals, making the assembly adaptable to various operational needs while maintaining a unified structure.
2Adaptability or versatility
If multiple separate controls are used for different functions, then the functional versatility is improved, but the device complexity increases
Solution Approach 1:
The patent merges the functions of multiple separate controls into a single operating assembly by integrating a first operating portion and a second operating portion within the same structure. This consolidation allows the assembly to provide multiple functions (rotation-based and pressing-based operations) without requiring multiple independent controls, thereby reducing overall device complexity while maintaining versatility.
Solution Approach 2:
The second operating portion is disposed at least partially in the first operating portion, creating a nested configuration. This nesting arrangement allows both operating portions to coexist within a compact space, enabling multiple functions to be accessed through a single integrated assembly rather than requiring separate controls, thus resolving the contradiction between versatility and complexity.
3Ease of operation
If a compact operating structure is used, then the device complexity is reduced, but the ease of operation may be compromised
Solution Approach 1:
The operating assembly incorporates dynamic elements including elastic members that provide responsive feedback during operation. The elastic members are configured to be elastically deformed when the second operating portion is pressed, providing tactile feedback to the user. This dynamic response enhances ease of operation by giving users clear feedback about their actions, while the integrated structure maintains simplicity.

AI summary
Provided are an operating assembly and a household appliance. The operating assembly includes a first operating portion and a second operating portion. The first operating portion is at least partially disposed in the second operating portion. The second operating portion can be located at and move back and forth between a first position and a second position of the first operating portion. When the second operating portion is located at the first position, the second operating portion can rotate relative to the first operating portion to generate a first electric signal; when the second operating portion is located at the second position, the second operating portion can drive the first operating portion to rotate to generate a second electrical signal during the rotation of the first operating portion; and the first operating portion can be pressed to generate a third electric signal.
