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

VSEngineering 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

Engineering Contradiction:

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.
