A food processor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processors pose safety hazards due to the risk of the lid being opened during operation, as they do not ensure the entire assembly is locked securely, leading to potential accidents when the blade is rotating at high speed.
Innovation Solution
A food processor design that incorporates a connecting rod mechanism, which locks the lid with the food processing cup and base only when the power is on, ensuring the entire assembly is secured during operation and preventing the lid from being opened until the power is cut off, thereby enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only the lid is locked with the food processing cup, then the structure is simpler, but the safety is insufficient because the entire assembly is not locked securely
Solution Approach 1:
The patent combines the lid locking mechanism with the food processing cup assembly locking mechanism into a unified system. The connecting rod integrates multiple locking functions: it locks the lid to the cup while simultaneously locking the cup assembly to the base, creating a comprehensive safety system that secures the entire assembly during operation.
Solution Approach 2:
The connecting rod serves as an intermediary element that mediates between the lid locking portion and the base locking mechanism. It transmits the locking force from the lid down through the cup assembly to the base, ensuring that all components are securely locked together as a unified system.
2Reliability
If multiple separate locking mechanisms are used for the lid and base, then the locking is more reliable, but the tolerances and errors are distributed across multiple components reducing accuracy
Solution Approach 1:
The patent merges multiple locking functions into a single connecting rod component. By concentrating all locking tolerances and manufacturing variations into one component rather than distributing them across multiple separate mechanisms, the system achieves better overall locking accuracy and reliability.
3Ease of operation
If the lid can be opened during operation, then the ease of operation is better, but the safety hazard increases due to high-speed blade rotation
Solution Approach 1:
The locking mechanism is designed to be dynamic and conditional. The connecting rod automatically engages the locking position when the lid is closed and the assembly is on the base, providing secure locking during operation. When the assembly is removed from the base, the locking mechanism disengages automatically, allowing easy lid removal for cleaning or maintenance.
Solution Approach 2:
The system applies preliminary locking action automatically when the lid is closed and the assembly is placed on the base, preventing the lid from being opened during operation. This preliminary safety measure is activated before operation begins and remains in effect throughout the operating cycle.

AI summary
A food processor comprising a food processor base (20) provided with a switch assembly (201) and a driving member (202), and a food processing cup assembly (10a, 10b) removably assembled on the food processor base (20).It comprises: a food processing cup (101); a lid (102a, 102b) for covering the food processing cup (101) and comprising a lid locking portion (1022a, 1022b); a connecting rod (103) comprising a connecting rod body (1031), an abutting portion (1032) and a connecting rod locking portion (1033) located at opposite ends of the connecting rod body (1031); and a connecting rod locking member (1042). When the lid (102a, 102b) is placed in position on the food processing cup (101) and the food processing cup assembly is assembled on the food processor base (20), the lid locking portion (1022a, 1022b) presses the connecting rod locking portion (1033) to drive the connecting rod (103) to move downward toward the switch assembly (201), so that the abutting portion (1032) triggers the switch assembly (201) to be turned on; when the switch assembly (201) is turned on, the driving member (202) drives the connecting rod locking member (1042) to drive the connecting rod (103) to continue to move downward, so that the lid locking portion (1022a, 1022b) is locked with the connecting rod locking portion (1033), and the connecting rod locking member (1042) is locked with the connecting rod (103).
