Creating operating session of a commercial laundry appliance utilizing lighting sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In commercial laundry settings, users face challenges in initiating a laundry session without direct interaction with the appliance's control panel, particularly due to hygiene concerns and the burden of using separate devices for commissioning and control.
Innovation Solution
A method utilizing a remote server to communicate with a laundry appliance through a network, where a target illumination sequence is sent to the appliance's lighting system, and the user records and compares this sequence using a remote device, allowing the appliance to initiate an operating cycle if the sequences match.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly interact with the control panel to commission the appliance, then the commissioning process is simple and direct, but hygiene concerns arise due to high-traffic contact areas
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the control panel. The user commissions the appliance through a mobile application that communicates with the control panel wirelessly, eliminating the need for direct physical contact with high-traffic surfaces while maintaining the commissioning functionality
Solution Approach 2:
The patent replaces the mechanical interaction (physical buttons and switches on the control panel) with an optical/electromagnetic system. The mobile device uses wireless communication (Bluetooth, Wi-Fi, or other protocols) to transmit commissioning commands to the control panel, substituting mechanical contact with contactless electronic communication
2Object-affected harmful factors
If users use a mobile phone to commission the appliance, then hygiene is improved by avoiding contact with control panels, but the process becomes more complex and requires separate devices
Solution Approach 1:
The patent merges the commissioning functionality with the mobile device application that users already employ for payment and account management. By integrating the commissioning feature into the existing mobile application ecosystem, the system eliminates the need for separate devices or complex multi-step processes, reducing overall system complexity while maintaining contactless operation
3Reliability
If users must physically press the start button, then safety is ensured by confirming user presence, but the process is cumbersome and requires direct control panel interaction
Solution Approach 1:
The patent implements a feedback mechanism where the control panel emits a distinctive audio signal (chime or tone sequence) that serves as confirmation of appliance readiness. The mobile device captures this audio feedback and uses it to verify that the correct appliance is selected and ready for commissioning, thereby confirming user presence and intent without requiring physical button presses

AI summary
A method using a remote server and a remote user device to operate a laundry appliance includes using the remote user device to communicate an appliance identifier to the remote server. The remote server communicates, to the laundry appliance, a target illumination sequence to be generated by a lighting system of the laundry appliance. The remote user device records and transmits a recorded illumination sequence generated by the lighting system of the laundry appliance and the remote server sends a command to the laundry appliance to initiate an operating cycle if the target illumination sequence matches the recorded illumination sequence.
