Chaotic Window Coding for Manual Picking Error Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual picking processes using window technology face challenges such as incorrect assignment of piece goods to windows, increased error rates due to continuous window movement, and difficulty in accurately identifying target windows, leading to inefficiencies and corrective actions.
Innovation Solution
Implementing a chaotic coding system for window identification, combined with a pick-by-voice or pick-by-light control system, where order pickers can freely choose a free window seat and confirm placement acoustically or visually, reducing errors and the need for corrective actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous window movement is used to maintain high productivity, then picking speed is improved, but error rate in window assignment increases
Solution Approach 1:
The system uses optical sensors to detect the position of pickers and automatically identifies which window is in front of each picker. This feedback mechanism replaces manual window identification, eliminating errors caused by continuous window movement while maintaining high picking speed. The sensor data is transmitted to the control system to automatically update the assigned window for each order line.
Solution Approach 2:
The patent replaces the mechanical/manual system of window identification (where pickers visually track and identify windows) with an optical sensing system. Cameras or optical sensors automatically detect window positions and picker locations, substituting human visual tracking with automated optical detection to maintain accuracy during continuous conveyor operation.
2Device complexity
If manual window identification is used to simplify the system, then device complexity is reduced, but picking precision deteriorates
Solution Approach 1:
The patent introduces an intermediary control system that acts as a bridge between the simple mechanical conveyor and the picking operation. This intermediary layer includes sensors and control logic that automatically match pickers with their assigned windows, adding minimal complexity while dramatically improving assignment accuracy without requiring complex mechanical window positioning mechanisms.
Solution Approach 2:
The system enables automatic self-identification of windows through optical sensors that detect window positions and picker locations without human intervention. The control system automatically performs the matching function, allowing the system to self-regulate window assignments without requiring complex manual identification procedures or intricate mechanical positioning systems.
3Reliability
If chaotic coding is used for window identification to prevent errors, then reliability is improved, but ease of operation worsens
Solution Approach 1:
The patent replaces the need for pickers to mentally process chaotic window codes with automated optical detection. Sensors automatically identify window positions and the control system handles the complex matching logic, freeing pickers from the cognitive burden of tracking chaotic codes while maintaining the error-prevention benefits of non-sequential window identification.
Solution Approach 2:
The control system serves as an intermediary that translates chaotic window codes into actionable information for pickers. Rather than requiring pickers to directly interpret complex coding patterns, the system automatically processes the chaotic codes and presents simplified guidance (such as visual indicators or audio cues) to guide pickers to the correct windows, maintaining reliability while improving ease of operation.

AI summary
The invention relates to a work place (10) for manual and ticketless stationary picking of piece goods (12) by a picking person (14) according to a picking order (80), said work place having: a window conveyor (14) which has a conveyor means (20) with a plurality of window areas (24) that can be optically distinguished from one another, each window area (24) comprising a rigidly defined region of said conveyor means (20), said region being suitable for receiving at least one piece good (12) and the window conveyor (16) running through a picking zone (26) allocated to the picking person (14); a supply region (28) where different types of piece goods (12) are supplied on a plurality of access areas (30), said supply region (28) being arranged relative to the window conveyor (16) such that the picking person (14) is able to grasp piece goods (12) manually from each access area (30) and place them on the window conveyor (16); a picking control system (50) which controls a warehouse management system and an order processing system (52, 64) and which conveys information (90) to the picking person (14) with regard to an access area (88) and an amount for removal (86) according to a line (82) of the picking order (80); and a device (40) for allocating a free, unoccupied window area (24) to the order line (82) by means of a selection and input of the picking person (14) once said picking person (14) has received the order line (82), with the free window area (24) being occupied following this allocation.
