Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-mounted object detection systems in closed environments, such as warehouses, struggle to effectively detect and avoid objects and pedestrians due to reduced visibility, leading to a need for improved object detection and avoidance capabilities.
Innovation Solution
Integration of a wireless communication system, such as UWB or Bluetooth, with object proximity devices like LiDAR, RADAR, or camera systems to detect and avoid objects and pedestrians by creating control, deceleration, and proximity alert zones based on vehicle speed and location, automatically adjusting speed and providing user alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vision-based sensors are used to improve object detection, then detection capability is improved, but the system cannot detect and avoid many objects that the vehicle encounters in the environment
Solution Approach 1:
The patent combines multiple detection systems (vision-based sensors, wireless communication transmitters, and proximity devices) into an integrated object detection system. This merging allows the system to leverage the strengths of each individual system while compensating for their weaknesses, thereby improving both detection precision and reliability simultaneously
Solution Approach 2:
The detection system is designed to handle multiple types of objects and scenarios through a unified multi-functional approach. The system can detect stationary objects, moving objects, and pedestrians using the same integrated system, making it universally applicable to various detection needs in warehouse environments
2Ease of operation
If the vehicle operates in tight spaces with reduced visibility, then maneuverability is improved, but the user's ability to identify objects is reduced
Solution Approach 1:
The system introduces wireless communication transmitters and proximity devices as intermediary elements between the user and the environment. These intermediaries provide additional information channels that compensate for reduced visual capability, allowing the user to maintain ease of operation in tight spaces while overcoming the difficulty of object detection
Solution Approach 2:
The patent replaces reliance on human visual detection (mechanical/optical system) with electronic detection systems including wireless communication and proximity sensing. This substitution allows the vehicle to operate in tight spaces with reduced visibility while maintaining object identification capability through non-visual sensing modalities
3Reliability
If the vehicle reduces speed to avoid objects, then safety is improved, but productivity is reduced
Solution Approach 1:
The system performs preliminary detection and classification of objects using multiple sensing modalities before the vehicle reaches them. By identifying potential hazards in advance and pre-planning avoidance maneuvers, the system can maintain higher speeds while still ensuring safety, thus resolving the contradiction between safety and productivity
Solution Approach 2:
The vehicle's speed and detection parameters are dynamically adjusted based on real-time environmental conditions and object characteristics. The system operates at higher speeds when the environment is clear and reduces speed only when necessary, optimizing the balance between safety and productivity through dynamic adaptation rather than static speed limitation
