Solution Overview

Problem

Laundry appliances, particularly commercial ones, often require unlocking via identifying markers like barcodes that can become unreadable or outdated, necessitating more reliable and updatable methods for user-specific session creation.

Innovation Solution

Utilizing acoustic waves modulated to carry an indicium of the laundry appliance, which are projected and received by a remote user interface device for demodulation, enabling session creation and appliance activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a printed identifying marker (barcode) is used to unlock the laundry appliance, then the appliance can be identified and unlocked, but the marker may become unrecognizable (partially or completely erased) or defunct due to information changes

Engineering Contradiction:
Improvereliability of identifying markerVSAvoidstability of printed marker
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent replaces the mechanical/optical identification system (printed barcode) with an acoustic identification system. The laundry appliance projects acoustic waves that carry identifying information, which are received and demodulated by a remote device. This substitution eliminates the need for physical markers that can deteriorate, as acoustic waves are generated electronically and can be updated without physical changes to the appliance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If an identifying marker is printed on the laundry appliance, then the appliance can be unlocked, but the marker requires physical updates when information changes

Engineering Contradiction:
Improveability to update identifying informationVSAvoidease of updating marker
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent implements a dynamic identification system where the identifying information is stored in memory and can be updated electronically. The acoustic waves are modulated with this information in real-time, allowing the appliance to adapt to information changes (such as appliance moves or reassignments) without requiring physical marker replacement. This makes the system highly adaptable while maintaining ease of manufacture since no physical updating process is needed.

Inventive Principle:
Principle #15Dynamics

3Reliability

If acoustic waves are projected to carry appliance indicium, then reliable identification without physical markers is achieved, but additional components (acoustic projector, receiver) are required

Engineering Contradiction:
Improvereliability of identification methodVSAvoidcomplexity of acoustic system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent leverages the universality of acoustic technology, which is already present in most smartphones and portable devices as speakers and microphones. The remote device uses its existing acoustic components to receive and process the identifying waves, rather than requiring specialized hardware. This approach maintains high reliability while minimizing additional complexity, as the system utilizes widely available technology rather than requiring proprietary components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
