Bicycle Design Race: 2D vs. 3D

  1. 1. START QUALITY COSTS 2DDESIGNED 3DDESIGNED WE ARE PEDALING MORE SLOWLY THIS PRODUCT? FULL SPEED AHEAD Engineers save time and have a more productive conversation thanks to tools that represent complex principles in 3D. Everyone understands the concepts. ROLLING RIGHT ALONG With 3D, engineers get the design right before their eyes. Interferences, collisions and hole misalignments are detected. Engineers design to cost targets with built-in bill of materials creation, cost estimation capabilities and manufacturability checks. TESTING, TESTING 1,2,3 DAYS EARLY 3D is used to visualize and share designs, helping to understand the parts in motion. Photographic-quality images and animations in full color allow clients to preview how the design will look and react. Physical models can be made quickly and inexpensively using a 3D printer so they can hold actual parts. TIRED? HARDLY, WITH ALL OF THESE TIME SAVINGS! Changes are made faster and with 100% accuracy. Files are automatically updated whenever a design change is made—from parts to assemblies to drawings—because all downstream engineering, manufacturing and marketing deliverables are linked to the 3D design models. Colleagues can start working on their materials before the design is finalized. THE FINISH LINE IS IN SIGHT All departments have worked concurrently, reducing the time needed to complete the project. 3D models are used to create User Guides, and websites and advertising are ready with images and animations weeks before the first bike rolls off the assembly line. ENGINEERING, MANUFACTURING AND MARKETING ARE PEDDLING ALONG PROJECT IS ON SCHEDULE FOR NOW Extra time and effort are needed to demonstrate a product concept in 2D. Getting engineers and their clients on the same page might appear easy, but complex concepts are difficult to illustrate and interpret. With 2D, costly prototypes are required to test designs. Changes require more prototypes to verify the new design. Additional delays result as design problems are found and parts are reworked to make them fit. PROJECT IS FALLING TO THE BACK OF THE PELOTON It’s hard to relay complicated design points to clients because many drawings are required. The delays created by the complexity of designing in 2D mean there is more pressure and tighter deadlines, as a result more design problems surface. ALMOST OUT OF THE RACE PROJECT LIMPS BEHIND AT A SINGLE-SPEED PACE PROJECT IS 20 DAYS LATE When a bicycle company creates a new product, several factors are key: attention to detail, product safety and timely delivery. The two scenarios below show how each project develops. On the left is a bicycle designed using 2D software, and on the right is a bicycle designed in 3D. Notice the challenges that arise in 2D manufacturing and find out why 3D helps expedite the project’s timeline. HOW 3D HELPS A BICYCLE COMPANY WIN The project falls further behind because changes to a single design element require making changes across dozens, possibly hundreds, of design files. Additional testing and careful proofing is required. In manufacturing, more interferences, collisions and hole misalignments are uncovered, further delaying launch. Assembly documentation is just now being created, and 2D drawings have to be updated again. Overrun costs for extra engineering time are piling up. More distressing, the cost to produce the design is almost twice what was targeted – meaning profitability is now in question. The entire project is completed by the deadline. Just as important, the project is on budget, and the manufacturing costs hit the targets set at the beginning of the project. Computer simulations allowed optimization of the bicycle’s aerodynamics, ensured proper function and reliability, and cut down on the cost of building multiple physical prototypes. Complex technical documentation was created quickly and easily before parts were finished, helping the client’s marketing and sales colleagues do their jobs and sell product in advance. And the winner is … 3D! That’s because it allows designers to identify and correct design flaws early, test components to verify they will function properly and explain to clients how parts work together. Engineers have time to add innovations such as stylized ergonomic parts that increase sales by making the final product look sleeker and ride faster. Happy clients and happy designers say it best: Choosing 3D really is that easy, no training wheels required. WINNING DESIGN CROSSES THE FINISH LINE ON TIME! PRODUCT LAUNCH HAPPENS 60 DAYS LATE – WITH ZERO FANFARE The project wraps up after nearly one month of delays. The product is adequate, but design problems are still possible because of the rush to complete the project. RIDE TO SUCCESS It’s easy to ensure the design functions as it should without physical prototypes. 3D simulation determines if a design is structurally sound, can survive dynamic forces and vibrations and validate aerodynamics to eliminate over-designed elements that might add weight and cost.

This increases the time required to make all views accurate, scaled and up-to-date. Identifying interferences, detecting collisions and estimating cost is difficult. Engineers hope they are on budget but have no real data to monitor costs.
