Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical barrier gate is used, then the barrier gate can physically block vehicles and pedestrians, but it is prone to mechanical failures and can cause accidents by smashing vehicles or harming pedestrians
Solution Approach 1:
The patent replaces the mechanical barrier gate system with an air holographic projection system. Instead of using physical mechanical components that can fail and cause harm, the invention uses optical fields to create a virtual barrier gate that provides visual guidance without physical contact, thereby eliminating mechanical failures and accident risks while maintaining the barrier function.
Solution Approach 2:
The patent creates a virtual copy of the barrier gate using air holographic projection. The holographic image replicates the appearance and function of a physical barrier gate without requiring actual physical components, allowing the barrier function to be achieved through optical information rather than physical material.
2Reliability
If a mechanical barrier gate is used, then the barrier gate can control access, but it requires constant monitoring by a specialized guardian
Solution Approach 1:
The patent implements a self-service system where the air holographic projection automatically controls access based on detected vehicle or pedestrian attributes. The system independently identifies targets, determines access permissions, and adjusts the holographic barrier without requiring human guardians, achieving full automation while maintaining reliable access control.
Solution Approach 2:
The patent incorporates a feedback mechanism where the system continuously detects attributes of approaching vehicles or pedestrians, processes this information, and automatically adjusts the holographic barrier state accordingly. This closed-loop control eliminates the need for human monitoring while ensuring reliable access control through real-time adaptive responses.
3Stability of the object's composition
If a physical barrier gate is used, then the barrier gate structure is fixed, but advertisements are difficult to switch or change
Solution Approach 1:
The patent applies dynamics by making the barrier gate advertisement content changeable while maintaining the structural stability of the holographic projection system. The air holographic projection can dynamically display different advertisement images and text without any physical modification, allowing flexible content updates while the projection apparatus remains stable and fixed in position.
Solution Approach 2:
The patent changes the optical parameters of the holographic projection to display different advertisement content. By modifying the projected light patterns, images, and text within the holographic barrier gate, the system achieves versatile advertisement display capabilities while the physical projection apparatus maintains its stable, fixed structure.
4Ease of repair
If components of the mechanical barrier gate fail or are damaged, then the barrier gate function is compromised, but the components are not easy to replace
Solution Approach 1:
The patent replaces mechanical components with an air holographic projection system that has no moving parts or fragile mechanical elements. The projection system uses optical components that are solid-state and have no wear, eliminating the need for component replacement while maintaining high reliability and continuous functionality.
Solution Approach 2:
The patent adopts a system where the holographic projection content can be easily updated or replaced without replacing physical components. The virtual barrier gate images and advertisements are digital information that can be changed instantaneously, equivalent to replacing disposable content rather than durable mechanical parts, achieving ease of replacement while maintaining system reliability.
