LiDAR Scanner Locking Assembly for Grain Bin Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurate measurement of grain volume in grain bins is challenging due to the cone-shaped filling and funnel-shaped distribution, which complicates traditional methods like visual observation and weight-based measurements, leading to errors that propagate through the supply chain.
Innovation Solution
An image scanning system utilizing LiDAR technology, coupled with a locking mechanism, is employed to generate precise point clouds of the grain area, allowing for accurate volume determination by rotating the image scanning head and base housing to capture distance information from any angle, while the locking system secures the system in place within the bin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional visual observation and weight-based measurements are used to measure grain volume, then the measurement process is simple, but the measurement precision is poor due to cone-shaped filling and funnel-shaped distribution
Solution Approach 1:
The patent replaces traditional mechanical measurement methods (visual observation and weight-based measurements) with LiDAR-based optical scanning technology. The LiDAR device emits laser beams to capture distance information and generate point clouds, enabling precise volumetric measurement of grain without mechanical contact, thereby resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent transforms the measurement approach by changing from direct physical measurement parameters (weight, visual estimation) to optical distance parameters. By measuring distance points from multiple angles and generating three-dimensional point clouds, the system achieves precise volume calculation through parameter transformation, overcoming the limitations of traditional methods.
2Measurement precision
If the image scanning system is installed without proper alignment, then the installation process is quick, but the measurement accuracy deteriorates due to incorrect positioning
Solution Approach 1:
The patent implements preliminary alignment actions during installation by using the locking system to secure the image scanning system at predetermined positions on the grain bin. The locking mechanism with curved edges and balls pre-configures the system geometry, ensuring correct alignment before measurement operations begin, thus maintaining both measurement precision and installation ease.
3Measurement precision
If the locking system uses rigid fixation without alignment features, then the securing strength is high, but the alignment precision is poor
Solution Approach 1:
The patent applies local quality by differentiating the functions of different components in the locking system. The locking plates provide rigid fixation for strength, while the curved edges and balls provide alignment functionality. This local differentiation allows each component to optimize its specific function, achieving both alignment precision and locking strength simultaneously.

AI summary
A locking system securing an image scanning device to a container includes a compressible material. The compressible material is disposed between a first securing plate and a second securing plate. A rotational element is disposed within curved edges of the first and second securing plates, where the curved edges each curve away from the compressible material. A shaft extends from the rotational element to the image scanning device. A fastener is secured through the first and second securing plates, and into the securing surface to lock the rotational element, and subsequently the shaft and image scanning device, in place. The locking system can be secured to a pitched surface to naturally position the image scanning device perpendicular to level ground.
