Recent
developments in technology have greatly influenced design techniques and opened
up new dimensions for the construction of kinetic structures. The dynamic
nature of the environment and the need for adaptive spaces led architects and
engineers to develop more innovative design solutions and structural systems
that can respond to variable environmental conditions and user needs. Those
systems allow not only transforming the structure into different geometric
shapes, but also transporting the structure from one place to another many
times. They may become self-standing structures as the conventional ones and be
used for different applications such as temporary protective covers for outdoor
activities, emergency shelters or bridges after natural disasters, exhibition
halls, pavilions, travelling theatres, concert halls and temporary buildings in
remote construction sites. Among the kinetic structures, deployable scissor
structures have great potentials for architectural applications thanks to their
extension and rotation properties.
This
research project addresses the study of kinematic design methodologies and fabrication
of deployable scissor-hinge structural mechanisms that can be used for novel
architectural applications. Mainly, the project is formulated as a continuation
of the EU-funded research project almost completed by an international team
including the coordinator and one of the researchers (Dr. Feray Maden) of this
project*. In the above-mentioned project, an existing geometric design methodology
for scissor-hinge structural mechanisms, so called “loop assembly method”
(developed by Chuck Hoberman), was improved and geometrically explained. The improved
method is a deductive approach, which allows users to define the structural
form of the deployable system and determine the geometry of the primary
scissor-hinge units according to the defined form and the number of the units
without using any optimization tools.
As
one of the results of this project, several different planar scissor-hinge
mechanisms were developed. However, until today spatial capabilities of these
developed mechanisms, their potential architectural applications and potential prototyping/
fabrication opportunities of these applications have not been investigated
sufficiently. This gap in the literature constitutes the main research problem
and the subject of the research project.
1.1. The Purpose
The
proposed research project mainly aims to investigate the opportunities to seek
new architectural applications for the mechanisms developed in the
above-mentioned project. Parallel to this aim, spatial capabilities of these
mechanisms will be investigated, too. Finally, and the most important
objective, fabrication opportunities of the selected architectural applications
will be investigated with scaled physical models that can work properly with
electronic control and necessary actuators.
1.2. The Scope
The
proposed research project deals with the architectural applications and fabrication
of the scissor-hinge structural mechanisms. Following topics will be covered
within the scope of the project: literature review and theoretical study on the
kinematic design of the selected mechanisms, geometric and kinematic analyses, revealing
the potential applications, enhancement of the mechanisms according to the architectural
need(s), overcoming the detailing problems with advanced digital fabrication
tools, arrangement of the motors and electronic control of the scaled models, and
construction of the selected mechanisms as scaled models.
