„Interface analysis"= function analysis!

1. Objectives & Requirements "Interface analysis"


1. The functions for the systems and subsystems are shown in full diagram.

2. The specifications of the data sheet are included.


1. The system structure of the product has been developed.

2. Die Zielsetzung des FMEA ist definiert.


2. Procedure "Interface Analysis"

1. Identify all interfaces of the system to be viewed

These can, for example, be subdivided into:

a) mechanical interfaces

b) hydraulic interfaces

c) Pneumatic interfaces

d) electric / electronic interfaces

e) interfaces with the environment

f) optical / haptic interfaces

2. If possible, identify and number these interfaces on the object / or model

3. Describe the functions at the interfaces. Use a simple sentence structure, e.g. noun - verb

3. Examples "Identification Interfaces" Cassette (1) (Fig. 1)
* Carrying out the cassette  (1)
* Position the cassette  (1)
* Position the cassette in the system  (1)
* Stacking the cassette (1)
* Ensure tamper protection  (1)
* Allow unlocking (1)
* Connect the connector  (1)
* Protect content  (1)
* etc. (1) Drive train (1) (Fig. 2) 
* Transfer torque to the hydraulic system (1)
* Receiving loads of front loaders (1)
* Ensure mechanical and structual connection to the engine (1)
* Transfer power from the motor (1)
* Ensure mechanical connection of hydraulic pumps (1)
* Transfer torque to wheels (1)
* etc. (1)

4. Results of "Interface Analysis"

1. Complete and systematic description of the interface functions

2. Functional system understanding of the parties involved

3. Input for the description of functional relationships (function networks)
