This thesis explores the computational process of generating and constructing interlocking frames. Its outcome delivers a sophisticated software tool that creates a three dimensional interlocking pattern, analyzes the intersecting conditions between members, and immediately provides instruction of its assembly sequence in animated visualization. An interlocking frame is a system that consists of short members spanning on a large surface where members lock each other at their mid-spans by simple notches. Such a system should be designed with consideration of its assembly sequence, as a static interlocking form may be described but impossible to assemble in any sequence. Given a three dimensional digital model of an interlocking frame, the feasibility of the disassembly sequence can be assessed by analyzing the geometric contact constraints between each member. The assembly sequence can then be obtained by reversing the disassembly sequence, and helps a designer to evaluate different options in the earlier stage of design. The proposed tool uses the genetic algorithm and graph searching algorithms to find optimized notching configurations that guarantee an assembly sequence. It can analyze various types of assemblies defined by planar surface contact constraints, and has a potential for further development into a versatile, automated 4D simulation tool.
