Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional footwear without electronic components is used, then the footwear maintains simplicity and low cost, but it lacks automated safety and navigation features

Engineering Contradiction:
Improveautomated safety and navigation featuresVSAvoidfootwear structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent embeds electronic components (detection tags, processors, communication modules) within the footwear structure, nesting them in the sole and upper portions. This allows the complex electronic system to be integrated into the footwear without significantly increasing external dimensions or visual complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The footwear system performs multiple functions: navigation guidance, collision avoidance, fall detection, and communication with external devices. The same electronic platform supports various safety and navigation features, making the complex system versatile rather than specialized for a single function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If detection tags and communication modules are added to footwear, then collision avoidance and navigation assistance are enabled, but energy consumption increases

Engineering Contradiction:
Improvecollision avoidance capabilityVSAvoidfootwear power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The detection tags and sensors operate periodically rather than continuously, activating at specific intervals or upon detecting specific conditions (such as approach to intersections or detection of potential hazards). This reduces overall energy consumption while maintaining reliable collision avoidance capability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses passive detection tags that can be energized by incoming signals from infrastructure, reducing the need for high-power active transmission. The footwear system serves itself by utilizing external infrastructure signals for detection and confirmation, minimizing its own energy expenditure.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If automated feedback systems are integrated into footwear, then navigation assistance is improved, but the footwear becomes more difficult to manufacture

Engineering Contradiction:
Improvenavigation assistanceVSAvoidfootwear production
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The footwear system is divided into separate modular components: detection tags, processing units, communication modules, and feedback mechanisms. This segmentation allows each component to be manufactured and tested independently, then assembled into the final footwear product, simplifying the overall manufacturing process despite the system's complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs intermediate processing layers and communication protocols that standardize the interaction between different components. This intermediary approach facilitates manufacturing by providing clear interfaces and communication standards between modules, reducing integration complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Presented are intelligent electronic footwear and apparel with controller-automated features, methods for making/operating such footwear and apparel, and control systems for executing automated features of such footwear and apparel. A method for operating an intelligent electronic shoe (IES) includes receiving, e.g., via a controller through a wireless communications device from a GPS satellite service, location data of a user. The controller also receives, e.g., from a backend server-class computer or other remote computing node, location data for a target object or site, such as a virtual shoe hidden at a virtual spot. The controller retrieves or predicts path plan data including a derived route for traversing from the user's location to the target's location within a geographic area. The controller then transmits command signals to a navigation alert system mounted to the IES's shoe structure to output visual, audio, and/or tactile cues that guide the user along the derived route.
