Solution Overview

Problem

Smart watches and similar devices face challenges in presenting useful information to users during activities like jogging or cycling due to limited screen size, and existing user interfaces are not optimized for safety and efficiency in outdoor activities, failing to provide tailored routes based on user preferences and environmental factors.

Innovation Solution

A device system that uses a thematic map database to determine and suggest routes based on user settings, past activity sessions, and environmental data, allowing users to approve and follow suggested routes, which can be adjusted in real-time based on location changes, and includes features for safety considerations like avoiding high-traffic or crime areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a smart watch presents detailed route information and activity data, then the user receives sufficient information for safe and efficient activities, but the limited screen size makes it difficult to display useful information in a readable format

Engineering Contradiction:
Improveinformation presentation qualityVSAvoidscreen size
Core Design Contradiction:
Loss of informationVSArea of stationary object

Solution Approach 1:

The patent transitions from two-dimensional screen display to three-dimensional haptic feedback through tactile patterns. The haptic interface encoder generates distinct tactile patterns that convey route information, activity status, and safety alerts without requiring visual display, effectively adding a sensory dimension for information delivery.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent replaces the traditional visual/mechanical display system with a haptic feedback system using an haptic interface encoder. This mechanical-to-haptic substitution allows information to be transmitted through tactile sensations rather than visual display, overcoming the screen size limitation.

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

2Reliability

If the user interface presents comprehensive safety information and route details, then user safety is improved, but the user becomes overloaded with unnecessary information that complicates the interface

Engineering Contradiction:
Improveuser safetyVSAvoidinterface complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies different haptic patterns to different zones or aspects of the interface, providing localized tactile feedback for specific information types. Different tactile patterns encode different meanings (route confirmation, safety warnings, activity status), allowing comprehensive information delivery without overwhelming the user with a single complex display.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses variations in haptic characteristics (intensity, frequency, pattern duration) analogous to color changes in visual interfaces. Different haptic patterns serve as distinct 'sensory colors' that convey different information states, enabling the user to distinguish between multiple types of feedback without visual complexity.

Inventive Principle:
Principle #32Color changes

3Productivity

If the device provides real-time route adjustments and environmental data processing, then route optimization and safety are improved, but the device complexity and energy consumption increase

Engineering Contradiction:
Improveroute optimization efficiencyVSAvoidprocessing system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent pre-calculates multiple route options and potential haptic feedback patterns before they are needed. The system prepares route alternatives and corresponding tactile encodings in advance, allowing real-time route adjustments without complex on-the-fly processing during critical moments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The haptic interface encoder autonomously translates route data and environmental information into appropriate tactile patterns without requiring complex intermediary processing. The system self-manages the conversion of multiple data inputs into intuitive haptic feedback, reducing the burden on central processing resources.

Inventive Principle:
Principle #25Self-service
