Solution Overview

Problem

Existing user interaction terminals in public places face inaccuracies in data collection due to random or repetitive selections by children, insistent users, and faulty button malfunctions, which are difficult to detect and correct in real-time.

Innovation Solution

A method that involves detecting selection times and filtering out distortive selections by analyzing the duration between consecutive selections and associating them with the state of the display page, allowing only valid and intentional selections to be recorded, thereby improving the precision of collected information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If selection buttons are made easily accessible in public terminals, then user interaction ease is improved, but data accuracy deteriorates due to random selections by children and repetitive presses by insistent users

Engineering Contradiction:
Improveuser interaction easeVSAvoiddata accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by recording the timing of each button press and storing it in memory before final data processing. This allows the system to later analyze the time intervals between presses and filter out invalid selections made by children or insistent users, thus preserving data accuracy while maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by analyzing the time intervals between consecutive button presses and using this information to determine whether a selection is valid. The server receives timing data, calculates intervals, and filters selections based on predetermined thresholds, providing a mechanism to distinguish intentional user selections from random or repetitive presses.

Inventive Principle:
Principle #23Feedback

2Quantity of substance

If the terminal collects all button presses without filtering, then data collection completeness is improved, but data reliability deteriorates due to inclusion of false selections from faulty buttons or random presses

Engineering Contradiction:
Improvedata collection completenessVSAvoiddata reliability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The system uses feedback by continuously monitoring the time intervals between button presses and comparing them against predetermined thresholds. This feedback mechanism allows the system to identify and filter out unreliable selections while maintaining comprehensive data collection, thus improving data reliability without sacrificing completeness.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system introduces an intermediary filtering mechanism that operates between data collection and final data processing. The server acts as an intermediary, receiving all button press data, analyzing timing patterns, and selectively accepting or rejecting selections based on temporal characteristics, thereby separating valid data from false selections.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If the system filters selections based on time intervals, then data accuracy is improved, but processing complexity increases due to additional time analysis and filtering steps

Engineering Contradiction:
Improvedata accuracyVSAvoidprocessing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system implements self-service by automatically recording timing data and performing filtering operations without requiring manual intervention. The terminal itself captures time stamps, and the server automatically calculates intervals and applies filtering logic, eliminating the need for additional manual processing steps while maintaining data accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses parameter changes by transforming the raw button press data into time interval parameters. By changing the representation from simple press counts to temporal intervals, the system enables automatic filtering based on predetermined threshold values, improving data accuracy through a relatively simple parameter transformation and comparison process.

Inventive Principle:
Principle #35Parameter changes
