Luggage Dimension Check Device with Perpendicular Light Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for checking luggage dimensions are often complex, heavy, and inflexible, requiring multiple mounting frames to meet varying airline requirements for dimensions and weight, and lack simplicity and adaptability.
Innovation Solution
A device with a display system of equidistantly arranged multicolored light sources in three perpendicular directions to indicate compliance with dimensions and weight requirements, allowing easy adaptation to different airline standards via barcode scanning or manual input, and including a scale for weight measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mounting frames are used to meet varying airline requirements, then the device can accommodate different dimension and weight specifications, but the device complexity and portability deteriorate
Solution Approach 1:
The patent implements a single mounting frame equipped with adjustable lighting means that can be reconfigured to meet different airline requirements. The lighting means includes multiple light sources arranged in three perpendicular directions that can be independently adjusted to indicate different dimension limits, allowing one frame to serve multiple airline specifications rather than requiring separate frames for each airline.
Solution Approach 2:
The lighting means are made adjustable and reconfigurable through electronic control, allowing the dimension indicators to be dynamically changed based on the airline being served. The light sources can be positioned at different locations and activated in different patterns to reflect varying size and weight requirements, transforming a static frame into a dynamically adaptable measurement system.
2Extent of automation
If a large and heavy device with complex structure is used to automatically determine weight and dimensions, then measurement accuracy and automation improve, but portability and simplicity deteriorate
Solution Approach 1:
The patent extracts the essential measurement function from complex automated systems and implements it through a simple scale integrated into the mounting frame. Rather than using heavy sensors and computer terminals to automatically determine dimensions and weight, the invention uses the frame structure itself as the measurement reference with lighting means to indicate compliance, removing unnecessary complexity while maintaining automated indication.
Solution Approach 2:
The patent replaces complex electronic measurement and display systems with a mechanical/optical indication system. Instead of using computers, displays, and printed outputs to show compliance, the invention uses strategically positioned light sources that visually indicate whether luggage meets requirements, substituting mechanical and optical elements for heavy electronic systems.
3Loss of information
If displays or printed outputs are used to show compliance information, then information precision improves, but device complexity and portability deteriorate
Solution Approach 1:
The patent uses color-coded light sources (typically green for compliance, red for non-compliance) to convey dimension and weight compliance information. The lighting means are arranged to illuminate in specific patterns that immediately communicate whether luggage meets airline requirements, providing clear visual feedback without requiring text displays or printed information.
Solution Approach 2:
The patent substitutes electronic displays and printing mechanisms with an optical indication system using light sources. The lighting means directly indicate compliance status through their illumination patterns and positions, eliminating the need for screens, printers, or other complex information display devices while maintaining effective communication of measurement results.
