Route Search Apparatus Automatic Start Point Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation devices for cycling require cumbersome operations for users to search for a return route to their starting point, as they need to separately perform measurement start and point registration operations, which can be inconvenient and time-consuming.
Innovation Solution
A route search apparatus with a measuring unit, position information acquiring unit, start point registering unit, and route searching unit that automatically registers the start point when measurement begins and allows users to easily search for a return route by detecting the operation of returning to the start point, thereby simplifying the process of finding a route back to the starting point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the navigation device requires separate point registration and measurement start operations, then the device can accurately track and measure cycling data, but the device complexity and ease of operation are compromised due to multiple required steps
Solution Approach 1:
The patent combines the point registration function and measurement start function into a single integrated operation. When the user presses the measurement start button, the system automatically registers the current position as the start point and begins measurement simultaneously, eliminating the need for separate registration and start operations while maintaining measurement accuracy
Solution Approach 2:
The system performs preliminary automatic registration of the start point before measurement begins. By pre-registering the current position as the start point when measurement is initiated, the system prepares the necessary data in advance, allowing measurement to start immediately without requiring separate user actions for both registration and starting measurement
2Reliability
If the user must manually register the start point separately, then the position data can be accurately stored, but the time required to set up measurement increases
Solution Approach 1:
The system merges the position registration process with the measurement start process into a single atomic operation. The current position is automatically captured and stored as the start point at the moment measurement begins, ensuring reliable position data storage while eliminating the time required for separate manual registration
Solution Approach 2:
The system performs automatic self-registration of the start point without requiring user intervention. When measurement is started, the system automatically captures the current position, stores it as the start point, and begins measurement, thereby eliminating the time users would otherwise spend on manual registration while ensuring accurate position data storage
3Adaptability or versatility
If the navigation device integrates both measurement and navigation functions, then the device versatility improves, but the device complexity increases due to multiple functions
Solution Approach 1:
The patent implements a unified navigation device that serves multiple functions: it acts as both a cycle computer for measuring cycling distance and time, and as a navigation device for route guidance and return route search. The system integrates these functions so that the same device can perform measurement, position tracking, and navigation without requiring separate dedicated devices
Solution Approach 2:
The system combines the measurement function and navigation function into a single integrated system. The measurement unit tracks cycling data while the position information acquiring unit and route searching unit provide navigation capabilities, allowing both functions to operate together in one device with shared resources and coordinated operation

AI summary
There is provided a route search apparatus including a measuring unit configured to measure a traveling distance or a traveling time, a position information acquiring unit configured to acquire position information of a current point, a start point registering unit configured to register the position information, which is acquired by the position information acquiring unit when the measuring unit starts the measurement, as position information of a start point, and a route searching unit configured to, if an operation of returning to the start point is detected, search a return route between the current point designated as a departure point when the operation of returning to the start point is detected and the start point designated as a destination.
