Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable spectroscopic measurement devices for cereals and oleaginous products face challenges in maintaining mechanical stability and achieving consistent measurements due to vibrations, which cause sample compaction and misalignment of light beams, making it difficult to handle size diversity and ensure homogeneity during transport.
Innovation Solution
A selective adjustment mechanism for the light beam in vertical and horizontal planes, combined with a rotary obturation device that forms a tilted ramp for grain flow and oscillates to improve homogeneity, along with adjustable plates for precise light source positioning, ensures parallel rays and consistent sample flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device is made movable for transport, then mobility is improved, but mechanical stability and measurement consistency deteriorate due to vibrations causing sample compaction and light beam misalignment
Solution Approach 1:
The patent implements adjustable and oscillating mechanisms that can adapt their configuration based on operational conditions. The light source positioning system includes adjustable plates and mechanisms that can be reconfigured during operation to compensate for vibration-induced misalignment, transforming a static system into a dynamically adaptable one that maintains measurement consistency despite mobility-related disturbances
Solution Approach 2:
The patent changes physical parameters of the system during operation, including the angle of the obturation device ramp and the position of light source components. By adjusting these parameters in response to detected misalignment or compaction issues, the system compensates for vibration effects and maintains reliable measurements while mobile
2Device complexity
If the light source position is fixed, then device simplicity is improved, but alignment accuracy deteriorates during vibrations causing measurement errors
Solution Approach 1:
The light source positioning system transitions from a fixed configuration to a dynamically adjustable one. Adjustable plates with multiple positioning holes and oscillating mechanisms allow the light source to be repositioned during operation to maintain proper alignment with the readout chamber and detector, compensating for vibration-induced misalignment without requiring complete realignment procedures
Solution Approach 2:
The system incorporates preliminary adjustment mechanisms that allow alignment to be established before operation begins, and preliminary compensation features such as pre-positioned adjustment holes and pre-configured oscillation amplitudes that prepare the system for vibration compensation before measurements start
3Productivity
If the sample flow is continuous, then productivity is improved, but sample homogeneity deteriorates due to grain compaction and entanglement during transport
Solution Approach 1:
The obturation device implements periodic opening and closing cycles that create controlled interruptions in the sample flow. This periodic action prevents continuous compaction by allowing grains to settle and redistribute between cycles, maintaining homogeneity while still achieving sufficient measurement throughput through repeated sampling cycles
Solution Approach 2:
The obturation device angle is made adjustable and can be oscillated during operation. By dynamically changing the ramp angle, the system optimizes grain flow characteristics to prevent compaction while maintaining continuous or near-continuous operation, balancing productivity with sample homogeneity
4Device complexity
If a single mechanical system handles all grain sizes, then device complexity is reduced, but handling effectiveness deteriorates for diverse cereal varieties with different diameters
Solution Approach 1:
The adjustable ramp angle mechanism serves multiple functions: it optimizes flow for different grain sizes, prevents compaction across various cereal types, and maintains homogeneity for diverse sample compositions. This single adjustable parameter provides universal adaptability to handle the full range of cereal varieties without requiring multiple specialized mechanisms
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 solution maintains mechanical stability and ensures consistent, accurate measurements by maintaining sample homogeneity and light beam alignment, even during vibrations, effectively addressing the challenges of size diversity and compaction in cereal and oleaginous samples.
Implementation Method 1
the grains which make up the sample are lightweight and different by their sizes. During its transport in a complex mechanism not adapted to the constraints of vibrations, the sample tends to be compacted, to no longer obey the laws of gravity
