AFTER PANDEMIC

The gap between us and our world

The covid19 epidemic has created an unfamiliar divide between people, objects, and the environment in the last two years. In addition, forced confinement to their homes has led to feelings of stress and depression. Now that the epidemic is slowing down, people are trying to regain a thriving vitality. Rebirth after an epidemic is not only a reawakening from the silence and uncertainty of the epidemic but also a reconnection with the fading emotions of human beings and objects. We always believe that a speed machine full of vitality can awaken the human heart and restore the dynamics of life.

Inspired by The Singing Ringing Tree

When I struggled to think of a way to develop my concept from the above, I came across the Singing Ringing Tree, a metal statue in Burnley, England. The tree is made of layers of steel tubes. Some of these have holes cut in them and act like flutes – when the wind blows it will produce a sound. This sculpture inspired me to think that if the wind in the environment resonates with the object, it seems to give life to the electric motorbike, giving a soulful resonance to an emotionless motor.

Insight

The most impressive performance of an electric vehicle is its quiet acceleration. As a result, speed can be converted into a low-frequency resonant sound that connects emotions and elicits an epidemic of renewal in the man-car relationship. As the Singing Ringing Tree has inspired me, what would an electric motorbike look like if it could employ this idea to make the sound for electric bikes?

The Concept

Resonant metal tubes of different lengths are installed on the body of the bike to create different frequencies of harmonic resonance with the speed of the ride, thus giving life to the electric motorbike. The metal resonance tubes are integrated into the motorcycle's exterior design and flow with the shape of the EUTERPE.

Sound Plan - Resonant Tubes Matrix

The EUTERPE has nine resonant tubes around the body, covering five primary ranges and three advanced ranges. When riding, the side wind blows at a near-vertical angle across the metal tube opening, causing the tube to resonate with it at the same frequency as the sound. As a result, the sound frequency not only increases and decreases with speed; the difference in wind pressure between the two sides of the bike as it leans around a bend also makes a difference to the sound.

Visual Plan

The metal resonance tubes, which are the core function of the EUTERPE, are exposed and neatly arranged on the sides of the vehicle and integrated into the body line. The internal combustion mechanism gives this heritage of visual memory to the user by the internal combustion mechanism. At the same time, the change in the structure of the electric vehicle has eliminated much of the space above the battery, allowing for a curved fold above the body to create a sense of suspension, giving it a light, penetrating, and futuristic feel through visual extension and linearity.

Variable Valve System

When the user rides the EUTERPE, the resonance tube will resonate in a Closed-pipe Standing Waves. However, when the user rides at speeds above 80km/h, the valve in the resonance tube will open, turning the tube into an Opened-pipe Standing Waves tube, which will also extend the resonance length and give life to the sound from the resonance tube.
