Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing currency sorting technologies do not effectively assist vision-impaired individuals in identifying and sorting currency notes by denomination, leading to difficulties in organizing and managing different denominations.
Innovation Solution
A currency sorter device equipped with an intake mechanism, identification mechanism using IR LEDs and sensors, and a distributor mechanism, which sorts currency notes into braille-lined wallet slots, providing audio and haptic feedback to aid users in identifying and organizing denominations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing currency sorting technologies are used, then currency notes can be sorted by denomination, but vision-impaired individuals cannot effectively identify and sort the currency notes
Solution Approach 1:
The patent introduces audio output as an intermediary between the currency note identification system and the vision-impaired user. The system captures images of currency notes, identifies denominations through image processing, and converts this visual information into audio feedback that vision-impaired individuals can perceive. This intermediary translation layer enables access to denomination information without requiring visual capability.
Solution Approach 2:
The patent replaces the traditional visual-mechanical interaction (looking at currency notes to identify denomination) with an optical-digital-audio system. Instead of relying on visual inspection of physical currency characteristics, the system uses image capture, digital image processing, and audio output to identify and communicate denomination information, substituting the visual-mechanical pathway with a technological pathway accessible to vision-impaired users.
2Ease of operation
If currency notes are sorted into wallet slots, then organization by denomination is achieved, but jamming occurs when slots overflow
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors the fill status of wallet slots and provides audio notifications to the user when slots are approaching capacity or have overflowed. This feedback loop allows users to及时了解 slot status and remove currency notes before jamming occurs, maintaining reliable operation of the sorting mechanism.
Solution Approach 2:
The system performs preliminary detection of slot capacity before overflow occurs. By monitoring and alerting users in advance when wallet slots are nearing their capacity, the system enables proactive user intervention to remove currency notes, preventing the jamming condition from developing in the first place rather than reacting after the problem occurs.
3Device complexity
If manual sorting by vision-impaired individuals is attempted, then no additional equipment is needed, but sorting efficiency and accuracy are severely limited
Solution Approach 1:
The patent enables the currency sorting system to perform the identification and classification work autonomously without requiring vision-impaired users to manually examine and sort each note. The system captures images, processes them through image recognition algorithms, identifies denominations, and directs notes to appropriate wallet slots automatically, allowing users to simply feed notes into the system and retrieve sorted results.
