Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual mail sortation systems face challenges in efficiently processing thick letters, flats, and small parcels due to mechanical or optical issues, and existing automated systems require significant investment or modification, making them impractical for many environments.
Innovation Solution
An augmented reality system using a headset with a high-resolution camera and transparent display that captures images of mailpieces to determine their destination bins, providing visual overlays to guide operators without requiring extensive training or equipment modification, and can learn from experienced operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated sorting equipment is used, then sorting productivity is improved, but device complexity and investment cost increase significantly
Solution Approach 1:
The patent introduces an augmented reality headset as an intermediary between the operator and the sorting task. The headset captures images of mailpieces, processes them through OCR, and provides visual guidance overlays, serving as a mediator that enhances human capability without requiring complex automated sorting machinery. This resolves the contradiction by achieving improved productivity through a lightweight technological intermediary rather than heavy automated equipment.
2Measurement precision
If optical character recognition is implemented, then sorting accuracy is improved, but reliability deteriorates due to light reflection and positioning issues
Solution Approach 1:
The system performs preliminary actions by capturing multiple images of the mailpiece from different angles and positions before final recognition. The augmented reality headset continuously captures images as the operator moves the mailpiece, allowing the system to pre-process and select the best image quality for OCR, thereby improving reliability before the critical recognition moment.
Solution Approach 2:
The system implements feedback by providing real-time visual overlays through the augmented reality headset that guide the operator on how to position and illuminate the mailpiece for optimal recognition. The system analyzes image quality metrics and provides feedback to the operator to adjust positioning, lighting, or angle, thereby improving recognition reliability in challenging conditions.
3Adaptability or versatility
If manual sortation is used, then adaptability to various mail types is maintained, but productivity decreases
Solution Approach 1:
The augmented reality system enables self-service by automatically capturing images, performing OCR, determining destination bins, and providing visual guidance without requiring external assistance or complex equipment. The operator independently completes the sorting task with enhanced capabilities, maintaining adaptability to various mail types while improving productivity through automated information processing.
4Ease of operation
If voice recognition systems are deployed, then ease of operation is improved, but reliability worsens due to noisy environments and pronunciation variations
Solution Approach 1:
The patent replaces the acoustic/voice-based system with an optical/image-based system. Instead of relying on voice recognition that is sensitive to noise and pronunciation, the system uses the camera to capture images of the mailpiece address and performs OCR. This substitution of the recognition mechanism eliminates the reliability issues associated with voice recognition while maintaining ease of operation.
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
Facilitates efficient sorting of various mail types with minimal disruption to existing processes, reducing training needs and allowing easy adaptation to different environments, while maintaining accuracy and reducing errors.
Implementation Method 1
The reasons can be purely mechanical or optical, for instance the address cannot be captured properly due to reflection of light
Implementation Method 2
a transparent display for signalling to the operator the relevant destination bin where the article is to be placed by highlighting or overlaying a visual artifact on a view of the sorting station
