Solution Overview
Problem
Existing tortilla makers lack the ability to produce tortillas of varying thicknesses, leading to inconsistent results and potential cracking or breaking of the handle and pressing plate during use.
Innovation Solution
An adjustable tortilla maker featuring a rotary shaft assembly with a movable rotary shaft seat, adjusting members, and a pressing shaft with a buffering mechanism, allowing for adjustable thickness settings and even material distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pressing plate is pressed directly without adjustment mechanism, then the structure is simple, but the tortilla thickness cannot be adjusted and material distribution is uneven
Solution Approach 1:
The pressing plate is made adjustable through a rotary shaft assembly that allows dynamic repositioning. The rotary shaft seat can rotate along the mounting post, enabling the pressing plate to be positioned at different heights to achieve varying tortilla thicknesses, transforming a static structure into a dynamic, adaptable one.
Solution Approach 2:
The pressing mechanism is divided into separable components: the pressing plate, rotary shaft assembly, mounting post, and locking portion. This segmentation allows independent adjustment of the pressing plate position while maintaining the overall structural integrity, enabling thickness adjustment without redesigning the entire device.
2Manufacturing precision
If excessive force is applied to press large materials, then the pressing effect is improved, but the handle and pressing plate crack or break
Solution Approach 1:
A pressing shaft is introduced as an intermediary component between the handle and pressing plate. The pressing shaft rotates during pressing, converting direct linear force into rotational motion, which distributes the pressing force more evenly across the material and reduces peak stresses that could cause cracking.
Solution Approach 2:
The pressing shaft is designed to rotate during the pressing operation, transforming static force application into dynamic rotational motion. This dynamic action allows the force to be distributed more uniformly over time and area, preventing concentration of stress at single points that would lead to cracking.
3Adaptability or versatility
If the pressing plate is fixed in position, then the structure is stable, but different thicknesses of tortillas cannot be produced
Solution Approach 1:
The rotary shaft seat is pre-equipped with a locking portion that can engage with the mounting post at predetermined positions. Before pressing, the user can adjust the pressing plate to the desired height and lock it in place, ensuring stable positioning during the pressing operation while maintaining the ability to reposition for different thicknesses.
Solution Approach 2:
The system transitions from a completely fixed structure to a dynamically adjustable one. The rotary shaft assembly allows the pressing plate to be moved to different positions along the mounting post, and the locking mechanism provides temporary stability at each position, enabling both adjustability and operational stability.
4Force
If the pressing plate contacts the base plate directly, then the pressing force is maximized, but the material distribution becomes uneven and tortillas of consistent thickness cannot be achieved
Solution Approach 1:
The pressing plate is decoupled from direct contact with the base plate through the adjustable rotary shaft assembly. This allows the pressing plate to be positioned at optimal heights above the base plate, enabling even material distribution before pressing, while still achieving sufficient pressing force through the lever action of the handle.

AI summary
An adjustable tortilla maker comprises a base plate comprising a lower forming surface and a pressing plate comprising an upper forming surface. When the pressing plate is in a pressing state, the lower forming surface is opposite to the upper forming surface. A rotary shaft assembly comprises a pressing plate pin shaft mounted on a rotary shaft seat, and the pressing plate is rotatably connected to the rotary shaft seat through the pressing plate pin shaft. A mounting post is connected to the base plate, and the mounting post extends along a thickness direction of the base plate. The mounting post protrudes from the lower forming surface of the base plate, and the rotary shaft seat is configured to be movably mounted on the mounting post. A locking portion is configured to lock the rotary shaft seat to the mounting post at a predefined position.
