Citylite Interlocking bicycle lights by Lars Beck

Home > Winners > #26401


DESIGN DETAILS
DESIGN NAME:
Citylite

PRIMARY FUNCTION:
Interlocking bicycle lights

INSPIRATION:
A personal need for a better bike light for my daily commuting around the city. I call it "Asian Inspiration".

UNIQUE PROPERTIES / PROJECT DESCRIPTION:
The Citylite bicycle light combines a simple and elegant design with easy handling and outstanding efficiency. It is powered by two lithium coin cells that are connected in parallel - a technical detail that simply doubles the batteries life span. The light angle is 220° so that the cyclist is visible even from the sides, a feature that secures a particularly safe ride. Moreover, it can swiftly be glided on and off the bicycle without tools. Form and function are united in Citylite in an exemplary manner through a straightforward design that is well-thought-out down to the last detail. Citylite is the worlds most compact set of bicycle lights,

OPERATION / FLOW / INTERACTION:
One unit separates into a front and a rear bicycle light that swiftly glides onto the handle bar and saddelstem. When the unit is separated each light automatically switch on and when assembled automatically switches off. Moreover, each light remembers the user’s preferred switch mode i.e. constant or flashing setting, minimizing the workflow/interaction to the absolute minimum, creating ultimate functionality through intelligent product design.

PROJECT DURATION AND LOCATION:
The idea for the product was born in 1993. However, the idea for the present configuration of the concept came in 2005 and production began in October 2011. The idea was born in Copenhagen in 1993 and project members involved have come from many different countries i.e. Denmark, Ireland, Belgium, Holland, China, Germany and the UK

PRODUCTION / REALIZATION TECHNOLOGY:
Lighthousing: Plastic injection molded POM. Lenses: Plastic injection molded PC Button: Plastic injection molded SEBS Electronics: PCBA

SPECIFICATIONS / TECHNICAL PROPERTIES:
Dimensions: 65,3x26x34mm

TAGS:
Bicycle lights, simplicity, elegance, design, efficiency and safety

RESEARCH ABSTRACT:
-

CHALLENGE:
Problem It’s not only bicycles that get stolen, but bicycle lights too. When arriving at your destination, to avoid theft usually meant lugging around two bulky lights in your pocket. The overall product design challenge was therefore to make a front and a rear bicycle light so small and compact that they could easily and conveniently be carried around in a pocket but without compromising standard safety features from a traditional bicycle light. Primary Technical Challenge To achieve rotational equilibrium around the handle bar tubular element in order for the front lamp to be able to remain positioned horizontally pointing forward without rotating around the handlebar and to get the patented Dura-Loc™ plastic molded snap-fit mechanism that keeps the two lamps interlocked when assembled into a single unit after use and which also functions as a snap-fit mechanism for mounting the two lights to the bicycle, to continue "snapping" repeatedly without losing its memory over time. Solution In order to prevent the material losing its memory overtime the design has been incorporated with a second snap fit mechanism that when activated latches the two snap fits under force after use. This allows the material to return to its original shape ready to exert the same clamping force over and over because the bending radius remains as specified every time. By combining the clamping force from the snap fit with the friction between the surfaces of the two parts and ultimately positioning the heaviest mass as close to the center of gravity as possible, it has been possible to balance out the moments around the handle bar and achieve rotational equilibrium. Other than the obvious challenges described above, then the absolute hardest part of the whole project was to convince the world around me that it could be done.
