Solution Overview
Problem
Conventional food processors face challenges in achieving thorough cleaning of the processing chamber, particularly the upper portion, due to reduced water flow strength, noise issues from increased blade speed, and potential safety hazards from user interference during automatic operations.
Innovation Solution
A self-cleaning food processor design with a detachable upper cavity portion and connecting section that guides water flow for 360-degree cleaning, combined with a safety locking mechanism to prevent accidental detachment and ensure smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the processing chamber part is made large to improve milklike liquid yield, then the yield is improved, but the crushing efficiency and uniformity deteriorate
Solution Approach 1:
The processing chamber part is divided into upper cavity portion and lower cavity portion that can be detachably connected. This segmentation allows the chamber to be large enough for high yield while maintaining effective crushing dimensions, as the upper portion can provide volume without compromising the lower portion's crushing performance.
Solution Approach 2:
The connecting section protrudes into the processing chamber part to guide water flow directionally. This dimensional feature creates a water flow guide structure that directs cleaning water along the inner side wall, improving cleaning coverage in the vertical dimension while maintaining horizontal crushing efficiency.
2Ease of operation
If the cup lid is made detachable for user convenience, then the ease of operation is improved, but the safety and operational reliability deteriorate
Solution Approach 1:
The safety locking mechanism is activated in advance when the cup lid is detached, preventing accidental operations before they can occur. The control module detects lid detachment and preemptively prevents machine operation, eliminating safety risks before they manifest.
Solution Approach 2:
The control module continuously monitors the state of the cup lid through feedback signals from the safety locking mechanism. When detachment is detected, the system provides immediate feedback by preventing operation, ensuring safety while maintaining user convenience for legitimate detaching needs.
3Productivity
If the water flow speed is increased to improve cleaning effect, then the cleaning efficiency is improved, but the noise level and energy consumption worsen
Solution Approach 1:
The connecting section is designed with a curved inner side wall that guides water flow smoothly. This curved structure directs water flow to rotate upward along the inner wall, improving cleaning coverage through directional guidance rather than increasing flow speed, thereby reducing noise and energy consumption.
Solution Approach 2:
The connecting section acts as an intermediary structure that redirects water flow from the crushing blade. Instead of directly increasing blade speed to improve cleaning, the connecting section mediates by guiding the existing water flow to cover harder-to-reach areas, achieving better cleaning without additional noise or energy.
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
Enhances cleaning efficiency, achieves uniform milklike liquid production, and ensures user safety by preventing unintended operation interruptions and liquid splashes.
Implementation Method 1
the connecting section is arranged to at least partially protrude toward an interior of the processing chamber part relative to the lower cavity portion... the connecting section is arranged to guide a water flow to change a direction of the water flow
Implementation Method 2
when the crushing blade drives the water flow to self-clean the processing chamber part
Implementation Method 3
the connecting section includes an annular seal... which seals the joint between the upper cavity portion and the lower cavity portion
