2. Checklist for embodiment design
Embodiment design ischaracterised by repeateddeliberation and verification Though individual factors may be closely
interrelated, designers can derive importantchecklist headings from the general objectives &constraints wich, moreover, provide them with auseful procedural order & a systematics check oneach step. The checklist thus not only provides astrong mental impetus, but also ensures thatnothing essential is forgotten in embodimentphase.

3. Basic rules of embodiment design
Fulfilment of the technical function
Economic feasibility
Individual & environmental safety
The basic rules ofclarity, simplicity,
& safety arederived from the
general objectives

ClarityIn what follows we shallbe applying the basicrule of clarity to thevarious headings of the
checklist
SimplicityFor technicalapplication the word“simple” means “not
complex”, easilyunderstood” and “easily
done”
3. Basic rules of embodiment design
SafetySafety consideration
affect both the reliablefulfillment of technicalfunction & also theprotection of humans &the environment. Directsafety method achievesafety through systemsor components actively
involved in theperformance particulartask. Indirect safetymethod involve the useof special protectivesystems & protectiveequipment.

Flowlines of force & theprinciple of uniform strength The problem solved in mechanical engineering
generally involve forces and/or motions and theirconnection, change, variation or channelling, andinvolve the conversion of energy, material &signals. The generally applicable function “channelforce” includes the application of load to, the
transfer of force between, and the transmission offorces through components and devices.

Principle of direct & short forcetransmission pathIn agreement we consider the following princile of
great importance : If a force or moment is to be transmitted from one
place to another with the minimum possibledeformation, then the shortest and most directforce transmission path is the best
This principle, which leads to the minimum numberof loaded areas, ensures :
Minimum use of materials (volume, weight)
Minimum deformation

Principle of matcheddeformationThe principles of mathced deformations state that
related components must be designed in such away that, under load, they will deform in the samesense and if possible, by the same amount.

Principle of balanced forceThose forces and moment that serve the function
directly, such as the driving torque, the tangentialtooth force and the load torque in a gearbox, can,
accordance with the definition of a main function,be described as functionally determined mainforces.
