Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Traditional navigation methods, relying on maps and auditory commands, are distracting and fail to allow unimpeded sight and hearing, particularly in situations requiring full attention, such as driving or riding a motorcycle.

Innovation Solution

A system that provides haptic directions using haptic output units, such as vibrations in handlebars, glasses, or smartwatches, to communicate navigation instructions without visual or auditory distractions, allowing users to focus on their surroundings while receiving directional cues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional navigation methods use maps and auditory commands, then navigation information is provided to users, but user attention is diverted from the surrounding environment

Engineering Contradiction:

Improvenavigation information deliveryVSAvoiddistraction from environment

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces auditory and visual navigation systems with a haptic feedback system that uses tactile sensations through the steering wheel. The mechanical vibration and tactile cues provide directional guidance without requiring the driver to listen to auditory commands or look at visual maps, thus eliminating the distraction problem while maintaining effective navigation information delivery.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If auditory commands are used for navigation, then hands-free operation is enabled, but the capacity to hear in an unimpeded capacity is reduced

Engineering Contradiction:

Improvehands-free operationVSAvoidimpeded hearing

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes auditory commands with haptic feedback through the steering wheel. The tactile vibrations and tactile cues provide navigation information through the sense of touch, enabling hands-free operation while preserving the driver's auditory capacity for hearing ambient sounds and traffic noises.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Loss of information

If visual maps are used for navigation, then detailed directional information is provided, but the capacity to see the environment is blocked

Engineering Contradiction:

Improvedirectional information deliveryVSAvoidblocked sight

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces visual map display with haptic feedback through the steering wheel. The tactile system communicates directional information through vibration patterns and tactile cues that the driver can perceive without looking away from the road, maintaining full visual awareness of the surrounding environment while delivering detailed navigation guidance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Loss of information

If the user looks at the map while traveling, then navigation directions are visible, but arrival time is delayed due to stopping

Engineering Contradiction:

Improvenavigation visibilityVSAvoidarrival time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent replaces visual map consultation with continuous haptic feedback through the steering wheel. The tactile system provides ongoing directional guidance that the driver can perceive without stopping or diverting attention, enabling continuous travel while maintaining access to navigation information and thus reducing arrival time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Systems, methods, and computer-readable storage devices for providing directions haptically such that sight and hearing can continue unimpeded. In one exemplary embodiment, a wearable device (such as earphones, ear rings, gloves, glasses, or other wearable objects) configured as disclosed herein receives directions to an intended destination for a user, the directions comprising a movement action and a distance to the movement action. The wearable device has multiple haptic output units and generates, through one of those units, a haptic output based on the directions. This allows the user to receive the directions through touch rather than looking at their mobile device or from audio.
