3D printing aids motorcycle safety

Screeching tires let electrical engineer and Vectolabs, LLC CEO, Faizal Ali know he almost became a National Highway Traffic Safety Administration (NHTSA) statistic. Ali had downshifted his motorcycle upon exiting a freeway, decelerating without activating the OEM brake light. Rapid deceleration through downshifting or coasting without brake light activation is common to motorcycles. The motorist behind Ali, however, had no indication of his deceleration until it was almost too late. An emergency stop prevented a rear-end collision, the type of accident that the NHTSA claims represents nearly one-third of all vehicle collisions.

“Immediately you think, ‘What an idiot; he almost hit me,’” Ali recounted. “But then I realized the driver didn’t know I was decelerating.”

Treating the incident as a Corrective Action, Ali sought change by asking “why?” at several levels. This led to the creation of Vectolabs, its flagship product Vololights and a Kickstarter crowdfunding campaign. Vectolabs seeks $50,000 to further develop Vololights’ plastic mold and lens optics.

Vololights - Enhanced Motorcycle Visibility

The first Adaptive Perceptible Deceleration Indicator, Vololights supplements a motorcycle’s OEM brake light by indicating level of braking urgency, even if a motorcycle’s actual brake is not actuated. Vololights consists of a motorcycle license plate bracket flanked by two horizontal rows of LED lights. An accelerometer and microprocessor monitor deceleration. When a pre-programmed trigger point is crossed, the LEDs flash based on urgency (hard braking vs. engine braking through coasting or downshifting).

• Upon moderate deceleration at five m/s^2, the LED rows alternately flash at 2 Hz. This alerts motorists to slow down and draws attention to the motorcycle’s OEM brake light. It’s also crucial — motorcyclists typically decelerate by first releasing the throttle, then applying a brake lever.

• Under hard braking at six m/s^2, both LED rows flash at 5Hz, alerting following drivers. Vectolabs selected of 5 Hz for hard braking as NHTSA-sponsored studies indicate it’s the optimal frequency to attract inattentive eyes.

Vololights Circuitry

Two wires secured by WAGO LEVER-NUTS™ transmit deceleration signals and power from the motorcycle’s 12 V battery to Vololights.

Easier = Safer:

An avid rider, Ali knows motorcycles are vibration-prone. Drawing on experience engineering aircraft assemblies, he specified WAGO LEVER-NUTS™ with vibration-proof Spring Pressure Connection Technology.

“Vibration-resistance was 90% of it,” Ali recalled. “I specified WAGO because I knew their terminal blocks. At a past job, we had problems with techs not torqueing [other blocks] properly. I didn’t want to mess with that — everything must be Spring Pressure.”

Ali also appreciated the simplicity of LEVER-NUTS™ lever-actuated terminations. Vololights are a DIY product; errors during complex installation could cause improper operation. Ali added these connectors to eliminate crimping, which is important because many DIYers don’t have crimpers.

Vololights Quick Connector

“With LEVER-NUTS™, pull up the lever, insert the wire and push it back down,” he explained. “It has to be simple to use; Vololights are likely not going to be installed by a trained electrician.”

A Bright Future:

Vololights is U.S. production-ready. According to Ali, U.S-based material costs are competitive with China, enabling Vectolabs to scout production sites.

“Efforts were made to remove labor content from the product,” Ali said. “All parts on the PCB minimize human handling.”

Shepherding Vololights from concept to production planning and on to marketing campaign has been “eye-opening” for Ali, the electrical engineer turned inventor. Fortunately, rapidly maturing design and manufacturing technologies, such as Additive Manufacturing (3D printing) are smoothing the way.

“3D printing is awesome because it allows us to get a few iterations in before making the silicone mold and eventually the steel mold,” Ali stated. “We made our prototype by 3D printing to check fit and feel. Then, [a third party] made the silicon mold once we signed off on the model.”

The efficiencies provided by 3D printing may also help extend Vololights beyond U.S. motorcycles. Encouraged by enthusiastic responses from European and Asian motorcyclists, Vectolabs eventually plans to market Vololights internationally. This may require design modifications to accommodate differently sized license plates. Ali also envisions scaling Vololights up to serve taxis and other fleet vehicles.

“If a taxi driver sees somebody hailing them, they will slam on the brakes to pick them up,” he said. “Most cars don’t do that, but taxis do it all the time. They’d see the most benefit.”

Ali said beyond incorporating LEDs, OEM brake light functionality hasn’t improved much since the 1970s. Through enhancements, such as Vololights, he envisions motorcyclists worrying less about other drivers and enjoying the ride.
