Introduction

• CEAD (Conceptual Engineering and Analysis based
  Design) uses a smarter approach called
  Constraint Driven Engineering Design Synthesis
  methodology to be used in the initial stages of
  product design cycle.

Product Development Has Never Been More
Challenging

• Businesses seek to develop product portfolios
  faster, cheaper, with fewer design iterations at
  higher quality.
• Product development processes manage conceptual
  design, engineering calculations, CAD, CAE and
  physical prototype phases linearly.
•  With each successive phase requiring more time
  stretching the time to market. 
•  The core challenge is in how to meet these
  expectations in the shortest possible time.
• while maintaining quality, predictability and
  engineering integrity.

Product Development Has Never Been More
Challenging

• One approach is in helping engineers see far and
  deep into the product performance at the
  conceptual design phase. 
• This ensures maximum engineering predictability
  and positively impacts overall timeline design
  quality, while reducing iterations and costs.  
• However, different and complex software tools
  make this iterative evaluation either time
  consuming or seriously sub-optimal.
• Even if done, some components of product
  performance remain outside the ambit of design
  evaluation as these tools lack seamless
  integration.

CEAD Product Development Process

•  Constraint Driven Engineering Design Synthesis
  A Smarter Product Development Process.
• A smarter approach is Constraint Driven
  Engineering Design Synthesis.
• This methodology innovates on the traditional
  bottom up product development by applying
  engineering constraints at the conceptual design
  stage.
• Whereby, shape, form, fit are a consequence of
  functional constraints and not the other way
  round.
•  This integrates mathematical equations with 2D
  conceptual geometry creation capability resulting
  in a qualitatively superior solution.

 Two Key Benefits of CEAD Product Development
Process
1. The solution is robust as it has already taken
into account all the use-case scenarios that the
mechanism is meant to fulfill and which an
engineer can describe as mathematical
constraints. 2. The solution is Pareto optimal
since engineers can impose any rational
quantitative measure from engineering,
manufacturing, functional or performance as a
mathematical objective constraint function that
is solved simultaneously.

Conceptual Engineering and Analysis Based Design
(CEAD)

•  Keeping in mind limitations of current tools,
  CADVision Engineers developing a new solution to
  support the Constraint Driven Engineering Design
  Synthesis methodology.
• The New Tool is CEAD, an integrated product
  design environment enabling preliminary hand
  sketches to conceptual CAE.
• That provides a rational design foundation for a
  more time-intensive CAD and CAE later in the
  product development cycle.

Conceptual Engineering and Analysis based
Design(CEAD)

• CEAD is the first level computer aided software
  tool.
• Engineer would use CEAD in creating sketches of
  concepts, progressing to synthesizing geometry.
• Finally analyzing the integrity of design to
  quickly assess practicality of a design
  concept.

The key Features of CEAD

• 1) With geometry and math concurrently described
  on the design canvas.
• CEAD enables engineers to intertwine any set of
  mathematically consistent engineering constraints
  to the design, even if they belong to different
  domains of physics.
• 2) CEAD has advanced optimization tools to
  perform multi-objective optimization.
• 3) CEAD enables first cut analysis of forces,
  torque stresses, etc using vector mechanics.
• 4) Simulation functionality in CEAD enables
  engineers to see deep into the product
  development cycle, be it in manufacturing or
  machine performance.

• In the design cycle, CEAD is the first bare-bones
  tool that an engineer would use to simulate and
  capture the mechanics of motion, play of forces
  or plot trends
•  Iterative arrive at an optimal design that truly
  reflects the integrated reality of imposed
  constraints.
