Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product presentation devices with multiple moving sensors become complex and expensive due to uncoordinated sensor movements, leading to poor scalability and increased complexity in detecting inventory across shelves.
Innovation Solution
A product presentation device with sensors positioned at the rear edge, featuring a sensor movement system or individually positioned sensors, and a product guidance structure that allows for direct detection of objects, enabling efficient inventory monitoring with reduced sensor equipment and adaptable detection angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple moving sensors are used to detect inventory across shelves, then detection coverage is improved, but device complexity and cost increase significantly
Solution Approach 1:
Multiple sensors are merged into a single sensor housing that moves together as one unit along the shelf. The sensor housing contains multiple sensors (e.g., ultrasonic, optical, infrared) that detect objects simultaneously, combining their detection capabilities while sharing a common movement mechanism, thereby reducing overall system complexity while maintaining comprehensive inventory detection coverage
Solution Approach 2:
The sensor housing is designed as a multi-functional device that performs multiple detection functions (ultrasonic detection, optical detection, infrared detection) simultaneously. This single multi-functional unit replaces what would otherwise require multiple separate sensing devices, each with its own movement mechanism, thus improving inventory detection coverage without proportionally increasing system complexity
2Measurement precision
If multiple moving sensors are deployed across shelves, then inventory detection capability is improved, but the number of components and costs increase linearly
Solution Approach 1:
Multiple sensors are combined within a single sensor housing that is moved along the shelf by one movement mechanism. This merging approach maintains comprehensive inventory detection capability while significantly reducing the total number of components compared to having separate moving sensors for each detection point
Solution Approach 2:
The sensor housing acts as an intermediary structure that carries multiple sensors and positions them along the shelf. This single intermediary housing replaces what would otherwise require multiple separate sensor mounting structures and movement mechanisms, reducing component quantity while preserving detection capability
3Measurement precision
If sensors are positioned at the rear edge with movement systems, then detection accuracy is improved, but ease of manufacture decreases
Solution Approach 1:
The sensor housing is designed to move automatically along the shelf using a simple movement mechanism (such as a roller or slider that follows the shelf edge). This self-service approach allows the sensor positioning system to be easily manufactured and installed without complex mounting structures, maintaining detection accuracy while improving ease of manufacture
