Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combat gaming systems using infrared for radio-controlled vehicles or drones face interference issues when transmitting data, lack multi-directional communication capabilities, and do not effectively simulate damage or control manipulation during combat, limiting the user experience.
Innovation Solution
A combat system incorporating both a transmitter and receiver encoded to avoid interference, with a processing unit that manipulates vehicle controls and provides audio-visual feedback, using pulsed infrared signals and a microcontroller to simulate damage and manage communication, allowing for multiple gameplay modes and user-adjustable settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the infrared transmitter and receiver are always active for communication, then multi-directional communication capability is improved, but self-interference occurs when the vehicle fires
Solution Approach 1:
The patent implements periodic switching between transmission and reception modes. The infrared transmitter and receiver are alternately activated in time-synchronized cycles, allowing the vehicle to both send and receive signals without simultaneous operation. This periodic action eliminates self-interference while maintaining bidirectional communication capability across multiple vehicles.
Solution Approach 2:
The system dynamically adjusts the operational state of the infrared transmitter and receiver based on real-time combat conditions. The microcontroller monitors whether the vehicle is firing or being targeted and switches the infrared components between active and inactive states accordingly, optimizing communication while preventing self-interference during gunfire bursts.
2Object-generated harmful factors
If the infrared receiver is shut down during firing to avoid self-interference, then self-interference is prevented, but communication with other vehicles is interrupted
Solution Approach 1:
The system employs periodic time-multiplexed operation where the infrared receiver is temporarily disabled only during the brief firing interval and automatically reactivated immediately afterward. This allows the vehicle to prevent self-interference during gunfire while maintaining continuous communication capability with other vehicles during non-firing periods.
Solution Approach 2:
The microcontroller pre-coordinates the infrared transmission and reception schedules among all vehicles in the combat system. Before any vehicle initiates firing, the system has already established time slots where receivers are appropriately disabled, preventing self-interference while ensuring communication channels remain available during designated reception windows.
3Adaptability or versatility
If the control system manipulates vehicle controls to simulate damage, then combat realism is improved, but control responsiveness may be affected
Solution Approach 1:
The control manipulation is applied selectively to specific vehicle functions rather than all controls. When damage is detected, the system modifies only certain control parameters (such as motor throttle response or steering sensitivity) to simulate damage effects, while leaving other controls fully responsive. This maintains combat realism without compromising overall vehicle controllability.
Solution Approach 2:
The degree of control manipulation dynamically adjusts based on the severity and location of detected damage. The microcontroller calculates appropriate control modifications in real-time, applying subtle changes for minor damage and more pronounced effects for severe damage, while always maintaining sufficient responsiveness for the player to retain control of the vehicle.

AI summary
Provided are examples of a radio controlled vehicle infrared combat system and methods of gameplay for radio controlled vehicles. In one aspect, the system is comprised of a 38 KHz IR transmitter, 38 KHz IR filtered receiver, an audio/visual display, and a processing unit. The system accepts signals from both the IR receiver and the vehicles control receiver and manipulates the control output to the vehicle to simulate damage. When firing, the IR transmitter is enabled and disabled. The processing unit disables the IR receiver when the IR transmitter is engaged to avoid hitting its own receiver. The processing unit has user-adjustable settings to allow for use in various types of RC vehicles including land vehicles, RC aircraft, and drones.
