Self-Checkout Settlement Device with Visual Packing Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In self-service checkout systems, customers find it difficult to easily check the light emission of the light emitting unit due to its location, often near display units or reading units, requiring them to turn their gaze away from packing to verify the light.
Innovation Solution
A settlement device with a light emitting unit positioned within the visual field of the operator near the packing unit, using a measuring unit to determine if a commodity is packed based on weight, and controlling light emission to indicate packing status with different colors or flashing patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the light emitting unit is provided near the display unit or reading unit, then the device structure is compact, but the customer cannot easily check the light emission without diverting gaze from packing
Solution Approach 1:
The patent applies dimensionality change by moving the light emitting unit from a horizontal arrangement (near display/reading units) to a vertical arrangement (above the packing area). This spatial repositioning in the vertical dimension allows customers to view the light emission status while maintaining their gaze on the packing area, resolving the contradiction between compact structure and ease of checking.
2Ease of operation
If the light emitting unit is positioned near the display unit, then space utilization is efficient, but the customer must turn gaze to check light emission status
Solution Approach 1:
The patent implements feedback by providing real-time visual information through the light emitting unit positioned above the packing area. The light emission status (indicating whether packing is complete or incorrect) is immediately visible to the customer without requiring them to shift attention, creating continuous feedback during the packing operation and eliminating information loss.
3Device complexity
If the light emitting unit is located near the reading unit, then the system integration is tight, but the customer cannot verify packing status without moving eyes
Solution Approach 1:
The patent maintains tight system integration while improving verification convenience by repositioning the light emitting unit in the vertical dimension above the packing area. This preserves the functional integration of the system components while changing the spatial arrangement to enable continuous gaze during packing verification, resolving the contradiction between integration and operational ease.

AI summary
A settlement device includes a packing unit located near a reading unit to pack a commodity, a symbol of which is read by a reading unit, a measuring unit to measure the packed commodity, a light emitting unit, determining means for determining, using data of weight measured, whether the commodity, the symbol of which is read, is packed, and light-emission controller for, if determining that the commodity, the symbol of which is read, is packed, causing the light emitting unit to emit light in a first form and, if determining that the commodity, the symbol of which is read, is not packed, causing the light emitting unit to emit light in a second form.
