Vehicle Cargo Wing Tag Reading Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to differentiate between items carried into a cargo bed and those that have not, due to electromagnetic waves from reading devices being emitted outside the cargo bed when the wings are open.
Innovation Solution
A reading control device that identifies when the cargo bed wings are open and controls the reading devices to emit electromagnetic waves only from the opened wing, reducing unnecessary tag reading outside the cargo bed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reading devices are provided on both wings to read tags inside the cargo bed, then reading coverage is improved, but electromagnetic waves are emitted outside the cargo bed causing false reading of tags around the cargo bed
Solution Approach 1:
The system segments the wing operation into individual states (left wing open, right wing open, both closed) and controls reading devices on each wing independently based on the specific open state, preventing electromagnetic wave interference while maintaining reading coverage
Solution Approach 2:
The reading device control is made dynamic by continuously monitoring wing open/closed states and adjusting which reading devices emit electromagnetic waves in real-time, ensuring waves are only emitted when the corresponding wing is closed or when necessary for items being carried in
2Loss of information
If reading devices emit electromagnetic waves when wings are open to read tags of items being carried in, then item tracking is improved, but distinction between items inside and outside cargo bed is lost
Solution Approach 1:
The system uses feedback from wing state detection to control reading device operation, where the open/closed state of wings provides information that determines whether reading devices should emit electromagnetic waves, enabling distinction between items inside and outside the cargo bed
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
This solution effectively reduces the reading of tags outside the cargo compartment by ensuring electromagnetic waves are only emitted downward from the opened wing, improving the accuracy of item tracking within the cargo bed.
Implementation Method 1
a reading device attached to an opened wing in the pair of wings to emit an electromagnetic wave for reading a tag

AI summary
A reading control device that controls reading of tags by reading devices provided at positions that are on a pair of wings attached to sides of a cargo bed of a vehicle, and face a cargo compartment includes: an identifying section that identifies that either one of the pair of wings is opened; and a reading control section that causes a reading device attached to an opened wing in the pair of wings to emit an electromagnetic wave for reading a tag, and does not cause a reading device attached to an unopened wing to emit the electromagnetic wave in a case where the identifying section identifies that either one of the pair of wings is opened.
