Innovation Solution

The proposed solution involves an electronic device with a communication module, processor, and display module, which receives sensor data from a wearable device. The wearable device includes a support frame, sensor module, driving module, and communication module, allowing it to transmit motion information to the electronic device for estimating the user's exercise ability based on exercise programs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a wearable device is used to collect motion data during exercise, then measurement precision of exercise ability is improved, but device complexity increases due to multiple sensors and processing components

Engineering Contradiction:

Improveexercise ability assessment accuracyVSAvoidwearable device structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system is divided into two separate devices: a wearable device that collects sensor data during exercise, and a separate electronic device that processes the data and provides feedback. This segmentation allows the wearable device to remain simple while the electronic device handles the complex processing tasks.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wearable device acts as an intermediary that collects raw sensor data and transmits it to the electronic device. This intermediary role allows the system to achieve high measurement precision without requiring the wearable device itself to be complex, as the heavy processing is offloaded to the electronic device.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If multiple sensors are integrated in the wearable device to capture comprehensive motion information, then measurement precision is improved, but weight of the wearable device increases

Engineering Contradiction:

Improvemotion data accuracyVSAvoidwearable device weight

Core Design Contradiction:

Measurement precisionVSWeight of moving object

Solution Approach 1:

The system separates the sensing function from the processing function. The wearable device contains only the necessary sensors and transmission components, while the electronic device handles the complex processing. This segmentation minimizes the weight of the wearable device while maintaining comprehensive motion capture capabilities.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If real-time feedback is provided during exercise through the electronic device, then ease of operation is improved, but loss of time in data processing and transmission increases

Engineering Contradiction:

Improveexercise guidance availabilityVSAvoiddata processing time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary data collection during exercise using the wearable device, storing the motion data for subsequent processing. This allows the actual analysis and feedback generation to occur after exercise completion, eliminating real-time processing delays while still providing comprehensive feedback.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The wearable device continuously collects motion data throughout the exercise session without interruption. This continuous data collection ensures no useful information is lost, while the processing can occur continuously or batched after exercise, maintaining ease of operation without significant time loss.

Inventive Principle:

Principle #20Continuity of useful action
