Parametric Adjustable Gym Bench
A personal multi-CAD product-design study exploring the mechanical arrangement of an adjustable gym bench. The assembly coordinates the welded frame, backrest and seat supports, pivot locations, adjustment brackets, locking positions, padding envelopes, foot support, and handling features as a coherent browser-ready model.

Project Overview
The project was used to practise parametric assembly planning around repeated adjustment positions and shared pivot geometry. The public case study focuses on product architecture, fit, motion clearances, and fabrication-aware component breakdown rather than claiming a tested or certified production design.
Project Category
Adjustable exercise equipment
Design Focus
Parametric adjustment, pivots, fit, and assembly architecture
Main Components
Steel frame, adjustable backrest, seat support, brackets, locking features, pads, foot support
Engineering Context
Personal product-design and mechanism study; no public certification claim
Software Context
Multi-CAD experience across SolidWorks, Siemens NX, Creo, CATIA, and Fusion 360; public GLB exported from SolidWorks
Web Output
High-resolution render and Draco-compressed GLB
Status
Personal public portfolio case study
Engineering Challenge
The main challenge was maintaining stable clearances and useful support positions while the backrest and seat moved through their adjustment range. Pivot locations, bracket thicknesses, frame spacing, pad envelopes, and locking geometry needed to remain coordinated without clashes.
Design Solution
The design uses a structured steel base, separate padded support panels, pivoting brackets, indexed adjustment features, and modular hardware. Geometry was recreated, modified, or checked through a multi-CAD workflow, and the latest assembly was exported from SolidWorks as a Draco-compressed GLB.
