Tupaia belangeri cognitive testing device with dynamic rolling door maze
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing testing devices for the cognitive ability of tupaia belangeri are inadequate as they scare the animals, leading to inaccurate determination of their learning cognitive ability due to reference formation and single-task limitations.
Innovation Solution
A testing device comprising a life cage, maze, rest bin, rolling door, camera module, control module, projection modules, touch module, and loudspeaker, which allows for multi-task cognitive ability testing by projecting graphic symbols, colors, and sounds, and recording the animal's behavior and responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional testing devices are used for cognitive ability testing of tupaia belangeri, then the testing structure is simple, but the animal is scared leading to inaccurate determination of learning cognitive ability
Solution Approach 1:
The testing device employs a rolling door that can dynamically open and close to control animal access to different maze sections. This dynamic control allows the system to guide the animal through the maze without sudden movements or scaring effects, thereby improving measurement precision of cognitive ability while reducing harmful factors
Solution Approach 2:
The rolling door acts as an intermediary mechanism between the control system and the animal. It smoothly controls the animal's progression through the maze without direct human intervention or scaring actions, enabling accurate cognitive assessment while minimizing stress and fear responses in the animal
2Measurement precision
If single-task testing is used, then the device structure is simple, but the cognitive ability assessment is limited and recognition accuracy is reduced
Solution Approach 1:
The testing device integrates multiple testing modalities including visual stimuli (projection modules displaying graphic symbols and colors), auditory stimuli (loudspeaker playing sounds), and tactile feedback (touch module). This multi-functional design enables comprehensive cognitive assessment across different sensory domains, improving recognition accuracy while maintaining device integration
Solution Approach 2:
The device combines projection modules, loudspeaker, touch module, and camera module into a single integrated testing system. These modules work together to present multi-sensory stimuli and record animal responses simultaneously, enabling comprehensive cognitive ability assessment without requiring multiple separate devices
3Adaptability or versatility
If multiple projection modules and sensors are added for multi-task testing, then the cognitive testing capability is improved, but the device complexity increases
Solution Approach 1:
Each module in the device is designed with multi-functionality: the projection module displays both graphic symbols and colors for visual testing, the loudspeaker provides auditory stimuli, the touch module delivers tactile feedback, and the camera module records both video and position data. This universal design reduces the need for separate specialized components, managing device complexity while maintaining versatile testing capability
