Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading systems inaccurately calculate the amount of objects loaded onto transporters, leading to potential overloading or underloading, which can result in inefficiencies and damage.
Innovation Solution
A loading system that includes a load-amount measuring unit, a difference computing unit, a storage unit, and a correcting unit to measure and correct the load amount based on measured differences, ensuring accurate load calculations and notifications to operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication between transporter and loader is implemented to send loading prohibition commands, then overload prevention capability is improved, but measurement precision of load amount deteriorates
Solution Approach 1:
The system implements feedback by measuring the load amount at two different stages (during loading and after loading), computing the difference between these measurements, and using this difference information to correct the load amount calculation. This feedback mechanism allows the system to identify and compensate for measurement errors, thereby improving measurement precision while maintaining the communication-based overload prevention capability
Solution Approach 2:
The patent replaces the purely communication-based overload prevention system with a hybrid approach that incorporates physical measurement correction. By introducing load-amount measuring units on both the transporter and loader, and using the difference between their measurements to correct the final load amount, the system substitutes the insufficient communication-only method with a more accurate measurement-correction mechanism
2Device complexity
If load amount is measured only during loading process, then measurement simplicity is improved, but measurement precision deteriorates due to not accounting for dynamic changes
Solution Approach 1:
The system performs a preliminary measurement of the load amount during the loading process, then performs a second measurement after loading is complete. By comparing these two measurements and computing their difference, the system identifies errors that occurred during the loading process and corrects the final load amount calculation, thereby improving measurement precision without significantly increasing system complexity

AI summary
A loading system that includes a transporter and a loader or a transporter is provided. It includes a load-amount measuring unit installed on the transporter that measures a load amount of an object loaded on the transporter; a difference computing unit computing a difference between the load amount measured by the load-amount measuring unit when the object is loaded, and a load amount measured by the load-amount measuring unit after a measurement when the object is loaded and at a time of traveling; a storage unit storing a difference value data indicating the difference computed by the difference computing unit; a correcting unit correcting the load amount measured by the load-amount measuring unit when the object is loaded, based on a correction rule calculated based on the difference value data stored in the storage unit; and a display unit displaying a corrected load amount obtained by correcting the load amount.
