Solution Overview

Problem

Industrial settings such as warehouses often face potential collision hazards between pedestrians and vehicles, particularly at intersections, due to the lack of dynamic and context-aware traffic control systems.

Innovation Solution

The development of dynamically configurable traffic controllers that provide different warning levels based on detected danger and potential collision hazards. These controllers use sensors to detect approaching vehicles and pedestrians and adjust warning signals accordingly, projecting warnings onto the floor or other objects if necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional fixed warning signals are used at intersections, then the system is simple and reliable, but it cannot adapt to different traffic conditions and provides insufficient context-aware warnings

Engineering Contradiction:
Improveadaptability to different traffic conditionsVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The traffic control system dynamically adjusts warning signals based on real-time detection of approaching vehicles and pedestrians. Sensors continuously monitor traffic conditions and the controller modifies signal intensity, color, and type (flashing vs. steady) according to detected hazards, transforming a static system into an adaptive one that responds to changing conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates sensor feedback loops that detect approaching traffic and pedestrians, then feed this information back to the controller which adjusts warning signals accordingly. This closed-loop feedback mechanism enables the system to adapt to different traffic conditions by continuously monitoring and responding to environmental changes.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If uniform warning signals are provided in all directions, then the system is simple to implement, but it cannot provide differentiated warning levels for different hazard directions

Engineering Contradiction:
Improvedifferentiated warning capabilityVSAvoidsignal configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system applies different warning signal characteristics to different directions based on local hazard conditions. Each direction can receive customized signals (color, intensity, flashing pattern) tailored to the specific traffic and pedestrian detection in that direction, rather than applying a uniform warning pattern to all directions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The warning signal system is segmented into multiple independent signal outputs facing different directions. Each signal can be independently controlled based on local detection, allowing the system to provide differentiated warnings for each direction while maintaining overall system coordination through the central controller.

Inventive Principle:
Principle #1Segmentation

3Use of energy by moving object

If warning signals are provided only when traffic is detected, then energy consumption is reduced, but warning continuity and alertness may be compromised

Engineering Contradiction:
Improveenergy consumptionVSAvoidwarning reliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system uses periodic or intermittent warning signals activated only when hazards are detected, rather than continuous signaling. This periodic action reduces energy consumption while maintaining reliability by activating warnings only when necessary, based on real-time detection of approaching vehicles or pedestrians.

Inventive Principle:
Principle #19Periodic action
