Running Watch Pace Change Goal Time Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional running devices fail to accurately display the estimated goal time when a runner changes pace during a marathon race, as they do not account for variations in speed, leading to uncertainty about reaching the goal point.
Innovation Solution
A running watch system that derives the pace between a start and goal point based on exercise data, calculates faster- and slower-pace estimated goal times, and displays these on a user interface, allowing runners to understand their time to the goal regardless of pace changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional running devices display estimated goal time based on initial pace, then the display is simple and easy to understand, but the accuracy deteriorates when the runner changes pace during the race
Solution Approach 1:
The system dynamically updates the estimated goal time calculation by detecting pace changes during running and recalculating based on the new pace. Instead of using a fixed initial pace, the system adapts the calculation in real-time, switching between different pace scenarios (faster, current, slower) to provide accurate estimates regardless of pace variations.
Solution Approach 2:
The system changes the pace parameter based on detected running conditions. When a pace change is detected, the system adjusts the pace value used in the estimated goal time calculation, providing multiple scenarios (faster-pace, current-pace, slower-pace) to account for different running states and improve accuracy.
2Loss of information
If the system provides multiple pace scenarios (faster, current, slower), then the information completeness improves, but the information overload increases making it harder to understand
Solution Approach 1:
The system segments the estimated goal time information into distinct pace scenarios (faster-pace, current-pace, slower-pace), each displayed separately with clear labels. This segmentation allows users to understand different possible outcomes without being overwhelmed by a single complex calculation, as each scenario represents a specific pace condition.
Solution Approach 2:
The display dynamically highlights or emphasizes the most relevant pace scenario based on current running conditions. When a pace change is detected, the system adjusts which scenario is prominently displayed or updates the scenarios in real-time, helping users focus on the most pertinent information while still having access to alternative scenarios.
Data Source
AI summary
An estimated goal time display system includes at least one processor; and at least one memory. The at least one processor is configured to perform the following according to a program stored in the at least one memory: first deriving that derives a pace that a user runs a distance set in advance based on exercise data obtained when the user is running; second deriving that derives an estimated goal time that the user will reach a preset goal point, a faster-pace estimated goal time that the user will reach the goal point if the user makes the pace a predetermined amount of time faster, and a slower-pace estimated goal time that the user will reach the goal point if the user makes the pace a predetermined amount of time slower; and display controlling that displays on a display the estimated goal time, the faster-pace estimated goal time and the slower-pace estimated goal time.
