Dual-Recess Dish Support Device for Stable Two-Handed Oven Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supporting and moving dishes, especially from confined spaces like ovens, often lack stability and safety due to limited contact with the dish, making them difficult to use effectively.
Innovation Solution
A device with a base and pairs of arms extending in opposite directions, featuring recesses that engage the dish for stability and serve as handles, allowing for secure support and movement of dishes by engaging more than half of the dish's circumference, enabling two-handed operation and safe handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device uses utensils adapted to simultaneously engage edges of a dish at multiple locations, then the device can support the dish, but it becomes difficult to use when removing a dish from an oven or other confined space
Solution Approach 1:
The device divides the engagement function into two separate pairs of arms: one pair for engaging the dish edges (first pair of arms) and another pair for providing handles (second pair of arms). This segmentation allows the engagement arms to be slender and easy to maneuver into confined spaces while the handle arms provide stable gripping surfaces for the user.
Solution Approach 2:
The device introduces an intermediary structure (the second pair of arms forming handles) that mediates between the user's hands and the dish. Instead of directly manipulating engagement arms, the user grasps the handles, which transmit force to the engagement arms, providing better control and stability during dish removal.
2Ease of operation
If a device uses locally grasp one edge of a dish, then it involves a one hand operation, but it may not offer a desirable level of stability when attempting to move a dish
Solution Approach 1:
The device merges the engagement function and the handling function into a single integrated structure. The first pair of arms engages the dish while the second pair of arms forms handles, combining both functions in one device that operates with two hands for enhanced stability.
Solution Approach 2:
The device transitions from one-handed operation to two-handed operation by adding the second pair of arms extending in the opposite direction. This dimensional change in usage (from one hand to two hands) significantly improves stability while maintaining ease of operation.
3Reliability
If a device uses recesses with perimeter exceeding one-half of circumference of a circle, then the device engages more than half of the dish's circumference for stability, but the device structure becomes more complex
Solution Approach 1:
The recesses formed by the arms serve multiple functions: they engage the dish edges for stability, guide the dish into proper positioning, and the arms themselves form the handles. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary
Devices include a base, and first and second pairs of arms extending from the base in opposite directions along a longitudinal axis of the device. Each of the first and second pairs of arms is spaced apart in a lateral direction of the device. The device further includes a first recess defined by and between the first pair of arms and a second recess defined by and between the second pair of arms to define first and second receptacles, respectively. Each recess has a perimeter exceeding one-half of a circumference of a circle. Accesses to the recesses are disposed on the longitudinal axis of the device and defined between opposing distal ends of the first and second pairs of arms. The first and second pairs of arms define, respectively, first and second sets of handles of the device.
