Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional biometric monitoring ear tags for livestock are costly, time-consuming to assemble, and suffer from poor waterproof, dustproof, and shockproof performance due to assembly gaps between the upper and lower shells, increasing the risk of damage to internal electronic components.
Innovation Solution
An injection molded biometric monitoring ear tag with a one-piece design that integrates a heat-conducting element and electronic components within an injection molded shell, eliminating assembly gaps and enhancing waterproof, dustproof, and shockproof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-piece female tag design is used, then assembly flexibility is improved, but manufacturing cost increases and assembly time extends
Solution Approach 1:
The patent merges the upper shell and lower shell into a single integrated shell structure that encompasses all electronic components. This one-piece design eliminates the need for separate assembly of multiple shell parts, thereby reducing manufacturing cost and assembly time while maintaining the protective function.
2Ease of operation
If a two-piece female tag design is used, then assembly flexibility is improved, but waterproof and dustproof performance deteriorates
Solution Approach 1:
The integrated shell design eliminates the assembly gap between upper and lower shells, creating a continuous protective barrier that prevents water and dust infiltration, thereby improving waterproof and dustproof performance to IP68 standard.
3Ease of operation
If a two-piece female tag design is used, then assembly flexibility is improved, but shockproof performance deteriorates
Solution Approach 1:
The one-piece shell structure eliminates weak assembly joints between multiple parts, creating a unified protective enclosure that provides superior shock resistance and mechanical strength, thereby improving shockproof performance.
4Ease of operation
If a two-piece female tag design is used, then assembly flexibility is improved, but component protection reliability deteriorates
Solution Approach 1:
The integrated shell provides a continuous protective enclosure around all electronic components without assembly gaps or joints, eliminating potential entry points for environmental contaminants and physical damage, thereby maximizing component protection reliability.
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
The one-piece design reduces production costs by up to 50%, shortens assembly time by nearly 80%, and improves performance to IP68, ensuring the reliability and longevity of internal components.
Implementation Method 1
The heat-conducting element is fixed to one side of the fixing bracket facing the ear and used to closely abut the ear to conduct an ear heat energy of the ear

AI summary
An injection molded type biometric monitoring ear tag (100) for attaching to an ear (201) of an animal (200) to be monitored, comprising a male tag (1) and a female tag (2, 2a). The male tag (1) is disposed on a first side (202) of the ear (201) and includes a base (11) and a protrusion (12) extending from the base (11). The female tag (2, 2a) is disposed on a second side (203) of the ear (201) and includes a fixing bracket (21), a heat-conducting element (22, 22a, 22b, 22c), an electronic component (23), and an injection molded shell (24, 24a). The heat-conducting element (22, 22a, 22b, 22c) is fixed to the fixing bracket (21) and closely abuts the ear (201). The electronic component (23) is fixed to the fixing bracket (21) and coupled to the heat-conducting element (22, 22a, 22b, 22c) to sense an ear temperature value. The injection molded shell (24, 24a) encapsulates the fixed fixing bracket (21), the heat-conducting element (22, 22a, 22b, 22c), and the electronic component (23), so that the heat-conducting element (22, 22a, 22b, 22c) is exposed from the injection molded shell (24, 24a). Therefore, it forms a plug-in fixing channel (C3, C3a), thereby fixing the male tag (1) and the female tag (2, 2a) relative to each other.
