Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional juicers pose safety risks due to small injection holes that can trap users' hands and require cutting fruits and vegetables into small pieces, and they can malfunction or break when using tools to insert materials.
Innovation Solution
A juice squeezing module with a side injection system featuring a hopper and guide protrusions to prevent hand insertion, a pressing rod for safe material insertion, and safety mechanisms to prevent accidental tool use and ensure proper coupling with the driving body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the injection hole is made small in conventional juicers, then safety is improved by preventing deep hand insertion, but the sectional area of the injection hole becomes small requiring materials to be cut into small pieces
Solution Approach 1:
The injection hole is repositioned from the top surface to the side surface of the cap, changing the spatial dimension of material injection. This allows the injection hole to have a larger cross-sectional area while the vertical depth remains limited, preventing deep hand insertion while facilitating easier material placement
Solution Approach 2:
Instead of making the injection hole small to prevent hand insertion, the invention inverts the approach by making the injection hole large but positioning it on the side where the depth constraint naturally prevents deep insertion. The hopper structure is also inverted from a top-down design to a side-mounted design
2Ease of operation
If tools are used to insert materials into the injection hole, then material insertion becomes easier, but the juicer may break or malfunction due to contact with the rotating screw
Solution Approach 1:
A pressing rod is introduced as an intermediary tool between the user and the material insertion process. The pressing rod is specifically designed to push materials into the injection hole without contacting the rotating screw, thereby maintaining ease of operation while preventing damage to the juicer components
Solution Approach 2:
The function of material insertion is extracted from the main juicing mechanism by providing a separate pressing rod that operates independently. This allows material insertion to be performed without involving the rotating screw, preventing potential damage while maintaining operational ease
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
The module allows for larger injection holes without deep hand insertion risks, facilitates easier material injection, and prevents accidents by ensuring only the pressing rod is used for material insertion, enhancing safety and usability.
