Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional motion picture viewing is used, then the viewing experience is simple and easy to implement, but the user engagement and immersion are insufficient
Solution Approach 1:
The patent combines multiple haptic feedback mechanisms (vibration motors, actuators, tactile elements) with the motion picture viewing system to create a multi-sensory experience. The handgrip section with vibration motors and the recoil section with actuators work together with the visual content to enhance user engagement while maintaining ease of use through automated synchronization.
Solution Approach 2:
The controller serves as an intermediary that receives signals from the motion picture system and translates them into appropriate haptic feedback responses. It coordinates the activation of vibration motors, actuators, and tactile elements based on the timing and intensity of events in the motion picture, bridging the gap between visual stimulation and tactile response.
2Productivity
If tactile simulation devices are added to enhance immersion, then user engagement improves, but device complexity increases
Solution Approach 1:
The tactile simulation system is divided into distinct modular sections: a handgrip section containing vibration motors, and a separate recoil section with actuators and tactile elements. This segmentation allows each component to perform its specific function independently while being controlled by a central controller, managing complexity through modularity.
Solution Approach 2:
The controller serves multiple functions by managing both the vibration motors in the handgrip section and the actuators in the recoil section. It processes signals from the motion picture system and coordinates multiple haptic feedback mechanisms, reducing overall system complexity through a centralized control architecture.
3Manufacturing precision
If recoil simulation mechanism is implemented, then realism of weapon firing sensation improves, but manufacturing complexity increases
Solution Approach 1:
The patent replaces complex mechanical recoil mechanisms with electromagnetic actuators that can be controlled electronically. This substitution allows for precise control of recoil timing and intensity through electrical signals from the controller, achieving high manufacturing precision while simplifying the mechanical assembly compared to traditional spring-loaded or weight-based recoil systems.
