Solution Approach 1:

The patent replaces wired mechanical connections with wireless communication technology. The activity tracking device transfers data to the display device wirelessly using radio frequency communication, eliminating the need for physical connectors and complex wired syncing procedures while maintaining data transfer reliability through protocol-level error handling and authentication mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system implements automatic data synchronization where the activity tracking device and display device autonomously establish connections and transfer data without requiring manual intervention. The devices automatically pair, authenticate, and sync activity data in the background, eliminating complex user-operated syncing schemes while ensuring reliable data transfer.

Inventive Principle:

Principle #25Self-service

2Productivity

If data transfer rate is increased for real-time display, then productivity is improved, but use of energy deteriorates

Engineering Contradiction:

Improvedata transfer rateVSAvoidenergy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic adjustment of connection intervals based on activity conditions. During high-intensity activities where real-time feedback is critical, the system increases data transfer frequency. During low-intensity or stationary periods, it reduces transfer frequency to conserve energy. This dynamic adaptation allows the system to optimize between productivity and energy consumption based on actual usage conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the connection interval parameter dynamically based on activity state. When real-time display is required, the connection interval is shortened to increase data transfer rate. When energy conservation is prioritized, the interval is extended. This parameter adjustment enables the system to achieve real-time data transfer only when necessary, balancing productivity improvements with energy consumption management.

Inventive Principle:

Principle #35Parameter changes

3Speed

If connection interval is scaled up for real-time updates, then speed of data transfer is improved, but loss of energy deteriorates

Engineering Contradiction:

Improvedata transfer speedVSAvoidenergy loss

Core Design Contradiction:

SpeedVSLoss of energy

Solution Approach 1:

The patent implements dynamic scaling of connection intervals based on real-time activity conditions and update requirements. The system monitors activity intensity and display update needs, adjusting the connection interval accordingly. During periods requiring real-time updates, the interval is scaled up to increase transfer speed. During periods where energy conservation is more important, the interval is scaled down, allowing the system to adaptively balance speed and energy loss.

Inventive Principle:

Principle #15Dynamics
