Solution Overview

Problem

Existing exercise mats and entertainment devices provide limited options for user interaction and fail to adapt to varying surface configurations, leading to restricted exercise programs and safety concerns.

Innovation Solution

An exercise mat with embedded LEDs and pressure sensors that communicates with an entertainment device via video input, allowing the device to detect the mat's position, orientation, and configuration, enabling dynamic adjustment of exercise programs and safety protocols based on the surface it is placed on.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the exercise mat uses a flexible body with embedded electronics, then the mat can detect surface configurations and provide adaptive exercise options, but the mat complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveadaptive exercise optionsVSAvoidmat complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mat is divided into multiple pressure sensing zones that independently detect surface configurations. Each zone can provide localized feedback, allowing the system to identify different surface types (soft, hard, inclined) without requiring a single complex sensing mechanism across the entire mat.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flexible mat body serves multiple functions: it provides the exercise surface, contains embedded pressure sensors for detection, and integrates lighting elements for feedback. This multi-functionality reduces the need for separate devices while maintaining adaptability across different surface configurations.

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

2Reliability

If the mat includes pressure sensors and lighting elements, then the mat can provide feedback and safety features, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvesafety featuresVSAvoidmanufacturing precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

Pressure sensors and lighting elements are positioned at specific locations on the mat where they are most needed for detection and feedback. This localized placement allows for standardized manufacturing of individual components while maintaining overall system reliability through strategic positioning rather than requiring high precision across the entire mat.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the entertainment device detects mat configuration using video input, then the system can adapt to different surfaces, but the system complexity increases

Engineering Contradiction:
Improvesurface adaptationVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The video camera acts as an intermediary between the physical mat configuration and the entertainment device's processing system. Instead of requiring direct complex communication protocols between sensors and the control device, the visual representation of the mat and its lighting patterns provides a simplified interface for detection and interpretation of surface configurations.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If the mat uses absorbent natural fibres, then the mat is comfortable for users, but sweat absorption becomes difficult to wash out due to electronics presence

Engineering Contradiction:
Improveuser comfortVSAvoidcleanability
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

A waterproof or sacrificial top layer is applied over the flexible mat body, creating a protective barrier that prevents sweat and moisture from penetrating to the electronic components beneath. This thin film layer maintains user comfort by allowing surface-level moisture management while protecting the electronics from contamination and making the mat easier to clean.

Inventive Principle:
Principle #30Flexible shells and thin films
