Solution Overview
Problem
Existing gas stoves face challenges in simple and convenient installation and removal of functional units, particularly the ignition unit, which requires effective heat protection and stable attachment to a base plate.
Innovation Solution
The design incorporates structurally identical holding units with clamping mechanisms for attaching the functional unit to the heat protection unit and base plate, allowing for easy assembly and disassembly, with spacers providing a cooling effect and electrical insulation, and elongated holes facilitating a positive connection for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the functional unit is attached to the heat protection unit and base plate using separate holding units, then the installation and removal process becomes complex and time-consuming, but if a single integrated holding unit is used, then the functional unit cannot be independently attached or detached from either component
Solution Approach 1:
The holding unit is designed with dual functionality to attach both the heat protection unit and base plate. The holding unit comprises a first holding means for the heat protection unit and a second holding means for the base plate, allowing a single component to perform multiple attachment functions simultaneously, thereby simplifying the overall assembly process while maintaining independent attachability.
2Reliability
If the functional unit is positioned close to the gas burner for efficient ignition, then heat protection becomes insufficient, but if positioned farther away, then ignition efficiency decreases
Solution Approach 1:
The heat protection unit serves as an intermediary component positioned between the gas burner and the functional unit. This intermediate structure provides thermal shielding to protect the functional unit from excessive heat while allowing the functional unit to remain in close proximity to the burner for reliable ignition operation.
3Productivity
If tool-free assembly is implemented for the holding unit, then assembly time and labor costs increase, but if tools are required, then assembly precision and reliability decrease
Solution Approach 1:
The holding unit is segmented into distinct holding means: a first holding means for the heat protection unit and a second holding means for the base plate. This segmentation allows each holding means to be independently designed for tool-free assembly while maintaining precise attachment, as each segment can be optimized for its specific attachment function without compromising overall precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables straightforward and stable installation of the functional unit, particularly the ignition unit, with enhanced heat protection and cooling, while allowing for independent installation and removal of components, reducing assembly effort and costs.
Implementation Method 1
The spacer can create an advantageous space between the functional unit and the base plate and/or the heat protection unit, which space can be used to cool the functional unit by allowing air to flow through the space and causing a cooling effect on the functional unit.
Implementation Method 2
a clamping unit can be understood to mean a holding unit that achieves a holding function by means of a clamping force that acts between two holding means
