1Ease of operation

If screen golf systems ignore terrain hardness, then the system complexity is reduced and easier to operate, but the realism and immersion of the golf simulation deteriorates

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent introduces terrain hardness as a variable parameter that affects ball movement simulation. By incorporating hardness values for different terrain types (fairway, rough, bunker, green) and using them to calculate bounce and rolling distances, the system dynamically adjusts simulation parameters to match real-world golf conditions, thereby enhancing realism without requiring complex hardware modifications

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a virtual copy of real golf course terrain characteristics by storing hardness values that represent different surface conditions. This virtual terrain model allows the simulation to replicate actual golf ball behavior on various surfaces, providing realistic feedback to players while maintaining system simplicity through software-based modeling rather than physical replication

Inventive Principle:
Principle #26Copying

2Reliability

If screen golf systems incorporate terrain hardness values and simulate ball movement accurately, then the realism of the golf simulation is improved, but the device complexity increases

Engineering Contradiction:
Improverealism of simulationVSAvoiddevice complexity
Core Design Contradiction:

Solution Approach 1:

The patent replaces complex mechanical or physical simulation systems with computational algorithms. Instead of using physical mechanisms to simulate ball bounce and roll, the system uses mathematical calculations based on terrain hardness values to determine ball trajectory and stopping points, achieving realistic simulation through software rather than hardware complexity

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

Solution Approach 2:

The patent manages complexity by using a simplified parameter-based approach. Rather than implementing full physics engines with multiple variables, the system uses terrain hardness as a key parameter that directly influences ball movement calculations. This parameter-driven approach achieves realistic simulation while keeping the computational model manageable and the system architecture simple

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If the ball movement simulation considers terrain hardness, then the accuracy of movement trajectory prediction is improved, but the computational requirements and processing time increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements a balanced simulation approach by considering terrain hardness for specific critical phases of ball movement (bounce and roll) rather than attempting to simulate every aspect of ball physics. This partial action approach provides sufficient accuracy for gameplay purposes while avoiding the computational overhead of exhaustive physics simulation

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent uses terrain hardness as a pre-defined parameter that simplifies computational requirements. By storing hardness values for different terrain types and using these to directly calculate ball movement, the system achieves accurate trajectory prediction without requiring real-time complex calculations, thus minimizing processing time while maintaining precision

Inventive Principle:
Principle #35Parameter changes
