Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooktop grates require manual lifting and alignment for cleaning or storage, which is inconvenient and inefficient.
Innovation Solution
A cooktop assembly with hinged burner grates that rotate between raised and lowered positions, utilizing support bases and a biasing member to facilitate easy access and storage, allowing the grates to be lifted and secured in an upright position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If grates are made removable for cleaning access, then cleaning accessibility is improved, but device complexity increases due to separate storage requirements
Solution Approach 1:
The patent combines the storage function with the cooktop surface itself by creating a recessed cavity that receives the grate when rotated upward. This eliminates the need for separate storage containers or spaces, as the storage function is merged into the existing cooktop structure. The grate transitions from a separate removable component to an integrated part of the cooktop assembly.
Solution Approach 2:
The patent introduces a hinged connection between the grate and the cooktop surface, allowing the grate to rotate between a horizontal cooking position and a vertical storage position. This dynamic mechanism replaces static removable/grate designs, enabling the grate to move seamlessly between operational and stored states without requiring separate handling or storage procedures.
2Ease of operation
If grates are made rotatable for easy access, then ease of operation is improved, but reliability may worsen due to additional moving parts
Solution Approach 1:
The patent introduces a hinge as an intermediary component that connects the grate to the cooktop surface. This hinge acts as a mediator that allows rotational movement while maintaining structural integrity. The hinge absorbs the mechanical stresses of rotation and provides a reliable connection point, protecting the overall system from the wear and tear that would otherwise affect the grate-cooktop connection directly.
Solution Approach 2:
The biasing mechanism automatically returns the grate to its horizontal cooking position after it has been rotated upward for access or cleaning. This self-service feature eliminates the need for manual positioning or complex locking mechanisms, reducing the number of moving parts that could fail while maintaining reliable operation. The spring-loaded biasing member provides consistent, passive force to maintain the grate in its operational state.
3Ease of operation
If biasing mechanism is added to hold grate position, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The biasing mechanism is designed to be self-regulating, using a spring-loaded system that automatically adjusts to maintain the grate in its horizontal cooking position. The mechanism requires no external control, adjustment, or additional power sources, as the spring force naturally compensates for the grate's weight and position. This self-service approach simplifies operation while adding minimal complexity compared to active positioning systems.
Solution Approach 2:
The biasing mechanism uses a spring element that exerts an upward force counteracting the downward force of gravity on the grate. This counterweight principle allows the grate to be easily held in the horizontal position without requiring complex mechanical stops or active control systems. The spring force provides a smooth, controlled resistance that facilitates easy rotation while maintaining stable positioning.
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
Enables convenient cleaning and storage of grates without the need for manual lifting, enhancing user experience and appliance accessibility.
Implementation Method 1
A biasing member is coupled to the support base. A biasing member is coupled to the first support base and exerts an upward biasing force on the grate.
Implementation Method 2
A biasing assembly includes a first housing, a second housing, and a biasing member disposed therebetween. The grate is rotatable between raised and lowered positions and biased toward the raised position by the biasing assembly.

AI summary
A cooktop for an appliance includes a cooktop base surface that defines an edge. A cooktop burner is mounted on the cooktop base surface. A support base is rigidly fixed with the cooktop base surface adjacent the edge. A grate is rotatably supported to the support base and is rotatable between a raised position and a lowered position to alternately cover and uncover the cooking burner. A biasing member is coupled to the support base and exerts an upward biasing force on the grate.
