Solution Overview

Problem

Existing soil cultivation devices that move automatically often rely on acoustic signals to indicate errors, which can be disruptive, difficult to locate, and inaccessible to hard of hearing or deaf individuals, making it challenging to identify and address error conditions effectively.

Innovation Solution

The implementation of an optical signal output device that projects a directional light projection onto a nearby surface, allowing users to easily locate the device when an error occurs, with the option for automatic emission or user-requested signaling, and the use of a control and evaluation device to select an optimal projection location and signal output device for clear directional indication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If acoustic signals (tone sequences) are used to indicate error conditions, then the user can be alerted to the error status, but the signals can have a disruptive effect on users and/or other people in the vicinity

Engineering Contradiction:
Improveerror indication reliabilityVSAvoidacoustic disruption
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the acoustic signal system with an optical signal system. Specifically, a light source (LED or laser) projects visual signals onto surfaces in the environment, substituting sound-based error indication with light-based indication. This eliminates the disruptive acoustic effect while maintaining reliable error notification through visual projections that can be seen from a distance.

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

2Loss of information

If acoustic signals are emitted regularly to locate the soil cultivation device, then the user can identify the device location, but it becomes difficult to locate the device if tones are emitted in regular but relatively far apart periods

Engineering Contradiction:
Improvedevice location informationVSAvoidtime to locate device
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The optical signal is projected continuously or near-continuously onto environmental surfaces before the user needs to locate the device. The light projection persists on walls, floors, or furniture, creating a persistent visual marker that the user can follow at any time, eliminating the need to wait for periodic signal emissions and reducing location time.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If acoustic signals are used to indicate error status, then the user can be notified of errors, but people who are hard of hearing or even deaf cannot take notice of the information signal

Engineering Contradiction:
Improveerror notification reliabilityVSAvoidaccessibility to different user groups
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The optical signal projection system serves multiple functions: it provides error notification, directional guidance to the device location, and continuous visual feedback. This universal visual interface is accessible to all users regardless of hearing ability, making the error notification system universally applicable to diverse user groups including those with hearing impairments.

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

4Ease of operation

If an optical signal output device is implemented to project directional light projections, then users can easily locate the device when an error occurs, but energy is consumed during signal projection

Engineering Contradiction:
Improvedevice location easeVSAvoidenergy consumption for signaling
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The optical signal projection operates periodically or on-demand rather than continuously. The control device activates the light source only when error conditions are detected or when signaling is actually needed, reducing energy consumption while maintaining ease of device location during critical moments.

Inventive Principle:
Principle #19Periodic action
