Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If camera-based systems are used to track customers, then customer tracking capability is achieved, but privacy concerns arise and the system becomes susceptible to lighting conditions and interference

Engineering Contradiction:
Improvetracking reliabilityVSAvoidprivacy concerns and susceptibility to interference
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces optical/mechanical camera-based tracking with pressure-sensitive sensor technology. The sensor flooring uses piezoelectric or strain gauge elements that convert mechanical pressure from footsteps into electrical signals, eliminating dependence on lighting conditions and privacy-sensitive visual capture while maintaining reliable customer presence detection

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the detection parameter from optical field characteristics (camera-based) to mechanical pressure characteristics (sensor-based). By measuring force and pressure applied to flooring tiles, the system achieves reliable tracking that is independent of lighting conditions, camera calibration, and privacy concerns associated with visual monitoring

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If optical imaging techniques are used for customer tracking, then motion detection is achieved, but the system becomes difficult to calibrate and maintain

Engineering Contradiction:
Improvemotion detection accuracyVSAvoidcalibration and maintenance difficulty
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The sensor flooring system is designed to be self-calibrating and maintenance-free. The pressure sensors automatically adapt to different pressure levels and foot patterns without requiring manual calibration, and the modular tile design allows for easy replacement rather than maintenance, significantly reducing operational complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The flooring system is divided into modular sensor tiles that can be independently installed and replaced. Each tile contains its own pressure sensing elements, allowing for localized replacement without affecting the entire system, thereby simplifying maintenance and reducing operational difficulty

Inventive Principle:
Principle #1Segmentation

3Reliability

If camera-based tracking systems are deployed, then customer presence is monitored, but the systems are cumbersome to install and susceptible to outside interference

Engineering Contradiction:
Improvecustomer presence monitoringVSAvoidinstallation complexity and susceptibility to interference
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex optical camera systems with simple pressure-sensitive sensor tiles that detect footsteps through mechanical force. This substitution eliminates susceptibility to vacuum cleaner interference and other environmental factors that affect camera-based systems, while simplifying installation to basic tile placement

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sensor tiles are designed as inexpensive, modular units that can be easily replaced if needed. The low cost of individual tiles allows for simple installation and replacement without requiring complex system-level interventions, reducing both installation complexity and maintenance burden

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
