Under the context of building a "pet-friendly society", this design focuses on pet-accompanied travel scenarios. Addressing core pain points in public transportation such as pet stress reactions, noise/odor control, and safety supervision, it innovatively proposes a "Mobile Safety Pod" concept. Through systematic technology integration, an intelligent transportation system is established to achieve breakthrough improvements in pet transportation safety and comfort, effectively resolving human-pet travel conflicts. The intelligent environmental control system integrates high-speed motor fans and ion deodorization devices, combined with replaceable botanical aroma modules, achieving 30-second air circulation cycles to effectively purify ammonia from pet waste. The life support system features spill-proof bowls, specialized trays, and crystal ice cooling devices, with emergency ventilation switches ensuring basic survival needs. The smart monitoring system enables GPS tracking and real-time camera surveillance via APP. This design incorporates diamond-shaped elements to create a robust appearance, with a simulation-optimized case structure that achieves a compressive strength of 800 N. The case features a snap-fit design, enabling multiple units to be securely stacked vertically without slippage.Under the trend where pets are regarded as family members, smart pet carriers with physical isolation designs ensure both the travel rights of pet-owning households and prevent disturbances to other passengers from pet hair, odors, and vocalizations. This design philosophy conveys respect for life while demonstrating a balance of public space rights. It drives the demand for emotionally considerate services and promotes the evolution of social values.The environmental monitoring module monitors temperature, humidity, and oxygen levels in real-time, automatically triggering an alarm upon detecting abnormalities. The independent electronically-controlled battery module supports up to 15 hours of continuous operation, meeting the demands of long-distance travel. Modular design reduces maintenance costs, while consumables such as plant-based aromatherapy materials are 100% biodegradable.
