Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods and devices for peeling beans are laborious, time-consuming, and not suitable for domestic or home use due to their bulky nature, leading to inefficiencies in processing time, water usage, and bean wastage.
Innovation Solution
A compact device with a driving motor and a bowl that abrasively impacts beans in water with a rough disc, using a barrier to retain beans and allow hulls to pass to a separate compartment, where a special filter collects the hulls, enabling simultaneous peeling and separation without soaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual peeling by rubbing soaked beans between palms is used, then peeling can be performed, but the process is time consuming and laborious
Solution Approach 1:
The patent replaces manual mechanical rubbing between palms with an automated mechanical system consisting of a rotating drum with abrasive surface and a feed mechanism. The drum rotates to abrasive the bean surface while the feed mechanism continuously supplies beans, automating the peeling process and eliminating manual labor while reducing time consumption.
Solution Approach 2:
The patent changes the physical state and surface properties of beans through controlled abrasive impact. By adjusting drum rotation speed, abrasive grain size, and impact force, the peeling process is optimized to remove hulls efficiently while maintaining bean integrity, thereby reducing both labor and time requirements compared to manual methods.
2Productivity
If blending devices are used for peeling beans, then peeling can be attempted, but beans are risk of being blended and multiple decanting is required
Solution Approach 1:
The patent applies localized abrasive action only on the bean surface through a rotating drum with controlled contact. The abrasive surface is confined to a specific region where beans are gently impacted, ensuring hull removal without affecting the inner bean structure. This localized treatment prevents over-processing and bean damage that occurs with blending devices.
Solution Approach 2:
The patent extracts and removes only the hull portion of the bean through controlled abrasive impact, leaving the edible bean intact. The separation mechanism selectively removes the outer layer while preserving the inner bean, eliminating the need for multiple decanting operations and preventing bean wastage associated with blending methods.
3Productivity
If known peeling devices are used, then peeling can be performed, but the devices are bulky and not suitable for domestic use
Solution Approach 1:
The patent employs a nested structure where the rotating drum is positioned within a compact housing, and the feed mechanism is integrated into the same space. The separation chamber is arranged concentrically around the drum, and the collection receptacle nests within the overall device structure. This nesting arrangement achieves functional capability while minimizing device volume for domestic use.
Solution Approach 2:
The patent integrates multiple functions into a single compact device: the rotating drum performs both peeling and initial separation, the housing provides structural support and collection, and the integrated mechanism handles feeding, processing, and output. This multi-functionality reduces the need for separate components, thereby reducing overall device size while maintaining peeling capability.
