Fruit pit removal device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fruit pit removal devices damage the exterior shape and shell of fruits with soft exteriors, such as premium dates, as they lack comprehensive protection during the removal process.
Innovation Solution
A fruit pit removal device with opposing top and bottom parts that accommodate the fruit, forming a closed position to cover it from all directions, using a shaft to eject the pit without applying force, and allowing manual or machine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pressure is applied on the fruit exterior side during pit removal, then the pit can be effectively removed, but the exterior shape and shell of soft fruits are damaged
Solution Approach 1:
The device divides the fruit into two halves by positioning the shaft to eject the pit through the center, while the top and bottom parts separately support and protect different portions of the fruit during the process
Solution Approach 2:
The shaft acts as an intermediary tool that removes the pit through the interior of the fruit rather than applying external pressure on the shell, thus protecting the exterior while achieving pit removal
2Stability of the object's composition
If the fruit is held firmly during pit removal, then the fruit remains stable, but the shell may be damaged
Solution Approach 1:
The device provides localized support at specific points (top and bottom surfaces) rather than constraining the entire fruit shell, allowing the fruit to remain stable during pit ejection while avoiding damage to the shell structure
Solution Approach 2:
The top and bottom parts are positioned to cradle the fruit before the pit ejection process begins, providing protective support that prevents shell damage during the subsequent pit removal action

AI summary
A fruit pit removal device (10) for removing a pit (50) from a fruit (48) has a shaft (64) to eject the pit from the fruit; opposing top (12) and bottom (14) parts, of which each includes top and bottom surfaces (16, 18, 22, 24) and a peripheral surface (20, 26) extending therebetween; the peripheral surface has front and rear surfaces (28, 30, 36, 38) and at least two opposing side surfaces (32, 34, 40, 42) extending therebetween; wherein the fruit pit removal device can be in an open or closed position; and when the fruit pit removal device is in a closed position, the bottom surface and the side surfaces of the top part and the top surface and the side surfaces of the bottom part cover the fruit peripheral surface (56).
