Ring Battery for Animal Ear Tag Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal ear tags with batteries become large and cumbersome due to the placement of batteries, leading to instability and increased risk of getting caught or bitten when the animal moves, as the center of gravity is not optimally positioned.
Innovation Solution
Designing the battery in the shape of a circular ring, allowing for a wider and flatter configuration that encircles circuit elements and fastening components, with the center of gravity aligned with the spike axis for stability and reduced size.

Engineering Contradiction Analysis
1Use of energy by moving object
If a battery is used to supply energy to active ear tags with electronics, then the ear tag can perform functions such as measuring conditions and radio transmission, but the ear tag becomes large and cumbersome, leading to instability and increased risk of getting caught or bitten
Solution Approach 1:
The battery is positioned to encircle the electronic circuit elements, with the circuit board arranged coaxially within the battery structure. This nested arrangement allows the battery to serve as both a power source and a protective housing for the electronics, eliminating the need for separate compartments and reducing overall ear tag volume.
Solution Approach 2:
The battery is designed in a ring shape rather than a conventional cylindrical or rectangular form, allowing it to wrap around the circuit board in a three-dimensional configuration. This dimensional change enables more efficient space utilization and creates a compact coaxial arrangement that reduces the ear tag's external dimensions.
2Duration of action of moving object
If the battery is positioned to provide sufficient energy storage, then the ear tag achieves long battery life, but the center of gravity becomes misaligned, causing the ear tag to oscillate and become unstable
Solution Approach 1:
The battery is designed with an asymmetric ring structure where the circuit board is positioned offset from the geometric center of the battery ring. By strategically placing the circuit board and adjusting the battery's ring geometry, the center of gravity is shifted to align with the spike axis, achieving balance and stability while maintaining sufficient energy storage capacity.
Solution Approach 2:
The battery ring structure acts as a counterbalancing element, with its mass distributed to offset the weight of the electronic components and housing. This creates a balanced center of gravity that aligns with the spike axis, preventing oscillation and ensuring stable wear on the animal's ear.
3Quantity of substance
If the ear tag is made larger to accommodate the battery, then sufficient energy storage is achieved, but the ear tag gets caught on objects or bitten by other animals more easily
Solution Approach 1:
The electronic circuit board is nested within the battery ring structure, with both components arranged coaxially. This integrated nested design eliminates the need for additional external housing space, allowing sufficient energy storage capacity to be achieved while maintaining a compact overall ear tag size that is less prone to getting caught or bitten.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Achieves a compact, balanced, and reliable animal ear tag design that minimizes size and weight while ensuring long battery life without the need for frequent replacements, enhancing stability and reducing the risk of interference or damage.
Implementation Method 1
A battery is also used in active ear tags for animals. Active ear tags in this sense are those which, within the scope of an included electronic circuit, have functions, such as, for example, measuring of conditions and radio transmission of the results, which require so much energy that a dedicated energy accumulator is required for this purpose.
