Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corner sensors are hardwired into the electrical system, then reliable power supply and signal transmission are achieved, but relocating the sensors becomes labor-intensive and time-consuming
Solution Approach 1:
The patent extracts the power supply function from the building's hardwired electrical system by incorporating an integrated power supply unit within the sensor assembly itself. This allows the sensor to operate independently without requiring connection to external electrical infrastructure, thereby enabling easy relocation without labor-intensive rewiring while maintaining continuous and reliable power supply.
Solution Approach 2:
The integrated power supply acts as an intermediary that eliminates the need for direct connection between the sensor and the building's electrical system. By including batteries or other power sources within the sensor housing, the system mediates the power delivery requirement, allowing the sensor to function reliably while remaining freely relocatable.
2Reliability
If motion sensors are used to detect oncoming traffic, then collision warnings can be provided, but the sensors require adjustment to change the field of view when relocated
Solution Approach 1:
The motion sensors are pre-adjusted during manufacturing to provide the optimal field of view for detecting oncoming traffic at intersections. This preliminary configuration eliminates the need for field adjustments when the sensor is relocated, allowing installers to simply mount the device and immediately achieve reliable collision warning functionality without requiring technical expertise for alignment.
Solution Approach 2:
The sensor assembly is designed with universal mounting capabilities and pre-configured sensors that can effectively monitor traffic patterns at various intersection locations without requiring location-specific adjustments. This universality allows the same device to be deployed at multiple different sites while maintaining consistent and reliable collision detection performance.
3Loss of information
If mirrors are placed at intersections, then pedestrians can see around corners, but the field of view is limited and collisions still occur
Solution Approach 1:
The patent replaces the passive mechanical mirror system with an active electronic motion detection system. Instead of relying on pedestrians to visually scan mirrors for oncoming traffic, the system uses motion sensors to automatically detect movement in adjacent pathways and provides active warnings through visual indicators, thereby overcoming the limited field of view and reliability issues of mirror-based systems.
Solution Approach 2:
The system implements feedback by using motion sensors to continuously monitor traffic patterns and providing real-time warnings to pedestrians through visual indicators when oncoming traffic is detected. This closed-loop feedback mechanism ensures that collision warnings are provided dynamically based on actual traffic conditions, unlike static mirrors that require active visual engagement and provide incomplete information.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easy relocation and setup of corner sensors, reducing the risk of collisions by providing a visible warning of oncoming traffic without the need for extensive reconfiguration, thus enhancing safety and efficiency in high-traffic areas.
Implementation Method 1
A first motion sensor is positioned within the housing and operatively connected to the power supply. The first motion sensor is oriented to sense motion within a first field of monitoring
Implementation Method 2
At least one visual indicator is operatively connected to the power supply, and the at least one visual indicator is changeable between an active state and an inactive state
