About Guardian Clogad Rothaíochta
Is clogad sábháilteachta é Guardian atá deartha do rothaithe atá bodhar agus balbh. Cuireann an clogad foláirimh chraitheacha agus léirscáileán ceann-in-airde in ionad foláirimh atá bunaithe ar fhuaim. Braitheann braiteoirí agus ceamaraí feithiclí atá ag druidim ó chúl, agus creathnaíonn an clogad go séimh chun rabhadh a thabhairt don rothaí. Splancann modúil dé-óid astaithe solais chun treo casta a thaispeáint. Tar éis tionóisce, cuirtear glao éigeandála ar bun go huathoibríoch, agus le tapaigh éadrom seolann sé teachtaireacht réamhshocraithe. Tá an sliogán déanta as aicrilónítríl búitaidiéin styirín éadrom, le líneáil cúr cuimhne agus cnaipe le haghaidh feistiú cothrom.

- Unique Properties
- Due to their inability to communicate effectively through speech and sound, deaf-mute individuals may face significant dangers when traveling, lacking essential information about road conditions. The deaf-mute safety helmet robustly protects cyclists with smart technology, sensors, and an advanced HUD system. It alerts them to traffic conditions through precise vibrations, sustaining alertness. The helmet significantly bolsters safety while cycling, lowering accident risks.

- Production Technology
- The design was developed through user-centered research, focusing on the travel challenges faced by deaf-mute individuals. Prototyping involved computer-aided design modeling and iterative testing with simulated vibration and head-up display feedback. The helmet is envisioned using lightweight acrylonitrile butadiene styrene for the shell, memory foam for comfort, and integrates sensors, cameras, and light-emitting diode modules to ensure safety and usability.
- Design Challenge
- The hardest part was designing a system that replaces sound-based warnings with intuitive, non-auditory feedback. Socially, deaf-mute cyclists are often overlooked, with few products considering their needs. Technologically, integrating sensors, HUD, and vibration modules into a compact, wearable form was complex. Limited reference cases and data made user research crucial. Overcoming these challenges required empathy, iteration, and creative use of existing tech in new ways.
- Research
- Amid honks and sirens, sound protects most but leaves deaf-mute cyclists exposed. We conducted user-centered design research aiming to improve their travel safety. Through interviews, observations, and journey mapping, we gathered insights from deaf-mute individuals and cyclists. Results revealed key dangers like missed warnings and lack of emergency help. This led to features like vibration alerts and auto-alarm, promoting inclusive design and raising awareness in both society and mobility products.
- Inspiration
- This project was inspired by the overlooked risks faced by deaf-mute cyclists in sound-dominated traffic environments. Motivated by a desire to create inclusive safety solutions, I explored how smart technology could bridge the sensory gap. Grounded in user-centered research and assistive tech studies, the design aims to challenge auditory bias in urban mobility and offer a more equitable, responsive riding experience for all.
- Project Duration
- The project started in June 2023 in China and finished in October 2024 in China.
- Operation Flow
- The helmet is easy to use—just wear it and ride as usual. It gently vibrates to warn you if something gets too close from behind, and flashes lights to keep you alert. When it's time to turn, it shows directions and flashes the right signal. If an accident happens, it automatically calls for help. With just a light tap, you can also send a preset message. It fits snugly with a twist of the knob, making cycling safer and more reassuring.
