Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a motor and rotation mechanism are added to rotate the grate, then heating uniformity is improved, but device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the grate rotatable instead of stationary. The motor-driven rotation mechanism allows the grate to dynamically change its orientation relative to the flame, enabling different portions of the grate to be heated uniformly by rotating it to various angular positions around the flame source.
2Adaptability or versatility
If height adjustment mechanism is added to the frame, then cooking versatility is improved, but device complexity increases
Solution Approach 1:
The height adjustment mechanism allows the grate to be dynamically repositioned to different heights above the flame. This dynamic adjustability enables versatile cooking by allowing users to optimize the distance between food and heat source for different cooking requirements, transforming a static structure into an adaptable system.
3Adaptability or versatility
If the grate is made rotatable, then cooking flexibility is improved, but manufacturing complexity increases
Solution Approach 1:
The rotatable grate design transforms a static cooking surface into a dynamic one that can be rotated to different positions. This dynamic capability provides cooking flexibility by allowing users to expose different areas of the grate to the flame, rotate cooked items for even cooking, and adjust the grate's orientation, while the patent addresses manufacturing concerns through practical implementation of the rotation mechanism.
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
The solution provides consistent and flexible heating of food items by rotating the grate over the flame, ensuring even cooking and allowing for the use of additional cookware, enhancing cooking efficiency and versatility.
Implementation Method 1
A power module and a motor are coupled to the frame. The motor is operationally coupled to the power module and the shaft. The motor is positioned to rotate the shaft.
Implementation Method 2
The grate is configured to position substantially horizontally over an open flame, such as a campfire. The grate is positioned to rotate coincident with the shaft such that food items that are positioned on the grate are positioned to be heated by the open flame.
Implementation Method 3
The grate is configured to position substantially horizontally over an open flame, such as a campfire. The grate is positioned to rotate coincident with the shaft such that food items that are positioned on the grate are positioned to be heated by the open flame.
