ROLE

SOFTWARE

YEAR

2025

01 / OVERVIEW

A portable refracting telescope and tripod system designed to combine optical adjustability, mechanical stability, portability, and manufacturability.

The team developed a sliding optical tube assembly that adjusts lens spacing for focusing and zooming while maintaining structural stability during use.

The complete system included telescoping tripod legs, an adjustable central hinge, custom optical components, a curved eyepiece assembly, and a collapsible structure for transportation.

02 / MY CONTRIBUTIONS

Mechanical Design & Structural Analysis

As part of the design team, I focused on the mechanical and structural development of the telescope and tripod system.

  • Designed and modeled components of the telescope and load-bearing tripod system in SolidWorks.
  • Developed CAD assemblies and engineering drawings while considering fit, tolerances, assembly, and manufacturability.
  • Performed analytical load calculations for the tripod under normal operating, peak-load, and uneven-ground conditions.
  • Evaluated tripod load distribution, compression forces, and buckling requirements using a structural factor of safety of 2.0.
  • Supported development of the 65-lbf load-bearing tripod design and evaluated structural stability under off-axis loading.
  • Performed SolidWorks finite element analysis on critical structural components, including the central hinge and telescope body.
  • Evaluated material options based on stiffness, weight, manufacturability, friction behavior, and structural performance.
  • Helped refine the final assembly for portability, stability, structural performance, and realistic manufacturing.

The complete telescope system was developed collaboratively by the project team. This section highlights my individual mechanical-design and structural-analysis contributions.

03 / SYSTEM DESIGN

The final system integrated optical, mechanical, structural, and ergonomic requirements into one assembly.

01 Optical Tube

Sliding tube sections allow controlled adjustment of lens spacing for focusing and zooming.

02 Hinge Assembly

Connects the tripod legs to the central support and provides angular adjustment.

03 Telescoping Legs

Adjustable leg sections provide height control, stability, and portability.

04 Eyepiece System

Curved lens housing redirects the optical path for more comfortable viewing.

04 / CAD DEVELOPMENT

SolidWorks was used to model the telescope components and verify that the parts integrated correctly within the final assembly.

CAD SolidWorks
ASSEMBLY 15 Parts
SUPPORT 3 Legs
LEG LENGTH 48 in

CAD development helped refine leg geometry, hinge placement, optical tube dimensions, and component interfaces while confirming that the system could collapse for transportation.

05 / MATERIAL SELECTION

Material selections balanced strength, weight, friction, durability, precision, and manufacturability.

ALUMINUM 6061-T6 Structural Components

Used for the optical tube, tripod legs, and structural elements because of its stiffness-to-weight ratio, machinability, and corrosion resistance.

BRASS Precision Interfaces

Used for lens-holder and threaded eyepiece components to provide precise threading and maintain optical alignment.

PTFE Low-Friction Surfaces

Used at sliding and pivot interfaces to reduce friction and improve controlled motion.

RUBBER Grip & Damping

Used at the tripod feet to improve traction and reduce vibration during use.

06 / STRUCTURAL ANALYSIS

Structural calculations were used to verify tripod stability under multiple loading conditions.

Concentrated near fixed screw

The central hinge showed its largest strain near the tripod-leg connection locations, while the telescope-body analysis showed the highest stress near the fixed screw.

08 / ENGINEERING TAKEAWAY

The project combined CAD, materials, structural mechanics, and optical considerations into one integrated mechanical system.

Analytical calculations and FEA helped validate structural performance while CAD modeling supported assembly, portability, and manufacturability.
