Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GPS navigation devices require users to hold them in their hands, disrupting navigation in difficult terrain and causing visual adaptation issues, especially at night, leading to safety concerns and inefficiencies.
Innovation Solution
A tactile navigation system integrated into a belt with a compass sensor, processing unit, and tactile actuators that communicate direction through the user's sense of touch, allowing for hands-free navigation and improved safety in various conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS navigation device is held in hand for checking position, then navigation accuracy is improved, but hiking efficiency deteriorates due to constant hand usage and stopping in difficult terrain
Solution Approach 1:
The patent combines the GPS navigation device with a belt worn around the waist, merging the navigation function with a body-mounted accessory. This allows the device to be continuously worn without interfering with hand usage for hiking tasks, thereby maintaining navigation accuracy while improving hiking efficiency by eliminating the need to constantly hold or stop to check position.
Solution Approach 2:
The patent introduces a tactile feedback unit as an intermediary between the GPS device and the user. Instead of requiring visual contact with a display screen, the tactile unit provides directional guidance through touch sensations on the belt, allowing users to navigate accurately while keeping their hands free and maintaining situational awareness of their surroundings.
2Loss of information
If GPS navigator display is used for navigation, then position information is obtained, but visual adaptation is disrupted especially during night conditions
Solution Approach 1:
The patent replaces the visual display system with a tactile feedback system. Instead of using a light-emitting display screen that disrupts night vision, the invention uses tactile actuators embedded in the belt to provide directional navigation information through touch sensations. This substitution eliminates the harmful visual light emission while maintaining effective position information delivery through the sense of touch.
3Reliability
If GPS device is constantly held in hand, then continuous position monitoring is achieved, but user safety deteriorates due to reduced awareness of surroundings
Solution Approach 1:
The patent shifts the interaction dimension from visual (looking at a screen) to tactile (feeling vibrations on the belt). By providing navigation feedback through touch sensations on the waist area, the system maintains continuous position monitoring capability while allowing users to keep their hands free and their visual attention on the environment, thereby improving situational awareness without sacrificing monitoring reliability.
