Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses for wireless sensor networks, when implanted in animals, cause stress due to the integration of sensor and radio communication units with batteries, leading to increased weight density and difficulty in acquiring natural behavior and state data effectively.
Innovation Solution
The electronic apparatus is designed with a case having separate capacity parts for the module unit and battery, with the module unit accommodated in one part and the battery in another, and a wiring coupling them, allowing for load decentralization and volume dispersion, reducing the stress on the animal and improving data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the sensor and radio communication unit are integrated with the battery in a single compact structure, then the device size is reduced, but the weight density increases and causes stress to the animal body
Solution Approach 1:
The device is divided into two separate capacity parts: a first capacity part accommodating the module unit (sensor and radio communication unit) and a second capacity part accommodating the battery. This segmentation distributes the weight throughout the device structure rather than concentrating it in one location, reducing the weight density at any single point while maintaining overall compactness.
2Volume of moving object
If the module unit and battery are integrated closely, then the device becomes more compact, but the local concentration of load increases causing stress to the animal
Solution Approach 1:
The internal structure is segmented into distinct capacity parts that are spatially separated. The first capacity part for the module unit and the second capacity part for the battery are positioned at different locations within the device housing, which distributes the load concentration and prevents excessive stress at any single implantation site.
Solution Approach 2:
Different regions of the device are designed with different functional qualities: the first capacity part is optimized for housing the module unit with its electronic components, while the second capacity part is optimized for housing the battery. This local differentiation allows each region to be optimized for its specific function while collectively achieving weight distribution.
3Duration of action of moving object
If the battery capacity is increased to extend monitoring duration, then the operation time is prolonged, but the device weight and volume increase
Solution Approach 1:
By segmenting the device into separate capacity parts, the battery can be optimized for maximum energy density in its dedicated space, while the overall device volume is managed through efficient spatial arrangement. This allows extended operation time without a proportional increase in total device volume.
Solution Approach 2:
The device utilizes three-dimensional spatial arrangement of capacity parts to accommodate the battery efficiently. By arranging components in multiple dimensions rather than simple linear expansion, the device can house larger capacity batteries without a direct linear increase in overall device volume.

AI summary
An electronic apparatus is provided which, even when the electronic apparatus configuring a node is implanted in the body of an object animal, makes the object animal hard to feel stress and can acquire effective data about the natural behavior and state of the object animal. As shown in FIG. 12, a module unit and a battery are arranged separated from each other. That is, an electronic apparatus according to the present embodiment 1 adopts a case including a first capacity part and a second capacity part both arranged separated from each other to thereby accommodate the module unit in an internal space of the first capacity part and accommodate the battery in an internal space of the second capacity part.
