Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shelling machines face challenges in adjusting the stroke of their jaws to accommodate almonds of varying sizes and orientations, leading to potential damage and requiring manual intervention that stops production and poses safety risks.
Innovation Solution
A sheller with a motorized eccentric element and adjustable lever system allows for automatic variation of the jaw stroke during operation, eliminating the need for manual adjustments and ensuring safe processing without production halts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of the stroke is performed by interrupting machine operation, then the stroke can be adjusted for different almond sizes and shell types, but production stops and operator safety is compromised
Solution Approach 1:
The patent implements dynamic adjustment of the stroke by allowing operators to modify the position of the movable jaw during operation through a control console. The stroke can be varied continuously without stopping the machine, transforming a static adjustment mechanism into a dynamic one that adapts to different almond sizes and shell types while maintaining production flow.
Solution Approach 2:
The patent replaces the manual mechanical adjustment system (requiring operators to physically access and adjust components during operation) with an automated control console system. This substitution eliminates the need for operators to intervene mechanically, thereby maintaining productivity while enabling stroke adjustment.
2Adaptability or versatility
If manual adjustment of the stroke is performed by interrupting machine operation, then the stroke can be adjusted for different almond sizes and shell types, but operator safety is compromised
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated control console that electronically controls the stroke variation. This eliminates operator exposure to moving parts during adjustment, thereby maintaining safety while preserving adaptability.
Solution Approach 2:
The system enables self-adjustment through the control console, where the machine automatically modifies its own stroke parameters without requiring operator intervention. This self-service capability maintains adaptability while eliminating safety risks associated with manual adjustment.
3Adaptability or versatility
If complex manual adjustment procedures are used with multiple connecting rods and cams, then the stroke can be varied, but the adjustment procedure becomes complex and time-consuming
Solution Approach 1:
The patent extracts the complex mechanical adjustment mechanism (multiple connecting rods, cams, and manual operations) and replaces it with a simplified control console system. This extraction eliminates unnecessary complexity while preserving the essential function of stroke variation.
Solution Approach 2:
The control console serves as a universal interface that can adjust the stroke for all connecting rods simultaneously through a single operational system, replacing the need for individual manual adjustment of each cam and connecting rod.
4Device complexity
If the jaw stroke is fixed, then the machine structure is simpler, but it cannot accommodate different almond sizes and shell types
Solution Approach 1:
The patent transforms the fixed jaw stroke into a dynamic parameter that can be varied during operation through the control console. This allows the simple machine structure to gain adaptability by enabling real-time stroke adjustment without complicating the overall mechanical design.
