Object Detection Cab Audio Control for Operator Awareness

Solution Overview

Problem

Operators of work vehicles face challenges in maintaining awareness of surrounding environment features and changes while concentrating on vehicle operation, leading to difficulties in balancing task performance and environmental awareness.

Innovation Solution

An object intelligence detection system that uses sensors to detect objects outside the work vehicle and adjusts sound levels within the operator cab to provide notifications, thereby redirecting the operator's attention to the environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the operator concentrates on controlling the work vehicle to perform tasks, then task performance efficiency is improved, but awareness of surrounding environment and objects deteriorates

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent introduces an intermediary system consisting of sensors, processors, and sound emission devices that mediate between the external environment and the operator. The sensors detect objects and conditions outside the cab, the processor analyzes this information, and the sound emission device communicates relevant environmental information to the operator through audible alerts, thereby restoring environmental awareness without requiring the operator's direct attention

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the operator maintains awareness of surrounding objects and environment, then environmental awareness is improved, but concentration on task performance deteriorates

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

The system implements a feedback mechanism where sensors continuously monitor the environment, the processor evaluates detected objects against predefined criteria, and sound emission devices provide selective auditory feedback to the operator. This feedback loop delivers only critical environmental information that requires operator attention, filtering out non-essential data to prevent distraction while maintaining situational awareness

Inventive Principle:
Principle #23Feedback

3Loss of information

If sound levels within the operator cab are reduced to alert the operator, then environmental awareness is improved, but operator comfort and communication quality deteriorates

Engineering Contradiction:
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system applies local quality by providing sound alerts at specific locations and times within the operator cab environment. Rather than uniformly reducing or increasing all sound levels, the system selectively emits auditory alerts only when specific objects or conditions are detected, and only in the specific context where operator attention is needed, while maintaining normal ambient sound levels for comfort and communication

Inventive Principle:
Principle #3Local quality

AI summary

An object intelligence detection system can selectively adjust the operation of one or more sound emission devices of a work vehicle to reduce a sound level within an associated operator cab. The reduction of the sound level within the operator cab can be triggered in response to different types of information, including information captured by one or more sensor systems regarding detected objects positioned outside of the work vehicle. Such captured information can also provide details used to determine whether detected object has a protected status, is performing a particular action or movement, or is located at a particular position relative to the work vehicle that qualifies for the reduction in the sound level within the operator cab. The reduction in sound level can also be triggered by the type of task being performed by the work vehicle, or the location of the work vehicle relative to a work zone.
