Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking robots lack stability and reliability in gripping cooking tools, leading to potential sliding and shaking during the cooking process, which can result in malfunctions and unsafe cooking conditions.
Innovation Solution
A frying robot equipped with a gripper mechanism featuring a pair of fingers with an insertion groove and fixing guide, assisted by chamfers, connected to a robot mechanism that includes a motor-driven ball screw system, ensuring stable grip and minimal sliding of cooking tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional gripping mechanism is used, then the structure is simple, but the gripping stability and reliability are poor
Solution Approach 1:
The gripper is divided into multiple functional components: finger bodies with insertion groove portions, fixing guides, and chamfer structures. Each component performs a specific function - the insertion groove portions grip the cooking tool, the fixing guides prevent lateral movement, and the chamfers facilitate insertion. This segmentation allows the complex gripping function to be achieved through coordinated simple structures.
Solution Approach 2:
The bent portion of the extension portion acts as an intermediary element that connects the cooking tool to the gripper fingers. This bent portion fits into the insertion groove portions and is supported by the fixing guides, creating a stable mechanical interface that transfers forces reliably between the gripper and cooking tool.
2Stability of the object's composition
If a simple gripping structure is used, then the device complexity is low, but sliding and shaking of cooking tools occur during cooking
Solution Approach 1:
Different regions of the gripper structure have specialized local qualities optimized for specific functions. The insertion groove portions have smooth surfaces for gripping, the fixing guides have precise geometric shapes for positioning, and the chamfers have angled surfaces for insertion assistance. This local optimization ensures stable cooking tool holding without requiring overall structural complexity.
Solution Approach 2:
The gripper structure employs asymmetric design elements, particularly in the fixing guides and chamfer configurations. The fixing guides protrude at specific asymmetric angles to match the geometry of the bent portion, creating a precise fit that prevents sliding while maintaining structural simplicity. The asymmetric chamfers facilitate one-directional insertion while providing stable retention.

AI summary
A frying robot according to the present embodiment may comprise: a frame; a robot mechanism installed on the frame; and a gripper connected to the robot mechanism. The gripper may comprise: a pair of fingers for gripping an extension portion of a cooking tool; and a finger-driving mechanism which moves the pair of fingers in a direction close to or away from each other. At least one of the pair of fingers may comprise: a finger body having an insertion groove portion formed therein, in which a bent portion of the extension portion is inserted; and a fixing guide protruding from the insertion groove portion and supporting the bent portion.
