Solution Overview

Problem

Existing systems require runners to perform short-distance runs to calculate recommended paces for long-distance races, which is inconvenient and does not accurately reflect their intrinsic abilities.

Innovation Solution

A system that calculates recommended running paces based on correlations between running distances and fastest paces of unspecified runners, correcting actual running paces of a runner to align with their intrinsic ability, using a correction function derived from these correlations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a runner performs a short-distance run (5 km or 10 km) to calculate recommended running pace for long-distance running, then the recommended running pace can be calculated, but it requires the runner to actually run at full speed for a distance shorter than the long-distance running which is inconvenient

Engineering Contradiction:
Improveaccuracy of recommended running paceVSAvoidconvenience for runner
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent uses GPS technology to acquire and store running pace data from the runner's actual long-distance run, creating a digital copy of the performance data. This eliminates the need for additional short-distance test runs while preserving the accuracy of pace measurement, as the system processes real running data captured during the actual long-distance event

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces a server as an intermediary that stores running pace data and performs the calculations. The server acts as a mediator between the runner's mobile device and the pace calculation algorithm, enabling the system to process and analyze running data without requiring the runner to perform additional physical tests

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a runner runs at a constant pace commensurate with their ability, then they can make a better record, but runners often slow down from the middle stage into the latter half due to running the former half at a faster pace

Engineering Contradiction:
Improveperformance consistencyVSAvoidrunning pace
Core Design Contradiction:
ReliabilityVSSpeed

Solution Approach 1:

The patent calculates the runner's intrinsic ability based on their actual long-distance run data and provides feedback in the form of a recommended running pace. This feedback mechanism allows the runner to adjust their pace strategy, running at a constant, ability-commensurate speed throughout the race rather than starting too fast and slowing down later

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent performs preliminary analysis of the runner's long-distance run data to calculate their intrinsic ability and recommended pace before the actual race. This advance preparation enables the runner to plan and execute a optimal constant pace strategy from the start, preventing the common mistake of running the first half too fast

Inventive Principle:
Principle #10Preliminary action
