Design for Disassembly Fundamentals

The primary goal of Design for Disassembly is to minimize the product's service life.

A modular design is recommended to reduce the number of assembly operations.

The use of laminates requires separation prior to reuse, making it a preferred material for disassembly.

Minimizing the use of different materials in an assembly reduces disassembly time.

Hidden joints are recommended in Design for Disassembly to reduce disassembly time.

Products with fragile parts are preferred for disassembly.

Product disassembly is an insignificant phase of the product lifecycle from an environmental and economic perspective.

Standardization of component assembly materials is unnecessary for disassembly.

Design for Disassembly only considers economic factors.

Optimizing component standardization reduces the need for specialized disassembly procedures.

Design for Disassembly (DfD)

DfD is a design strategy that considers the future need to disassemble a product for repair, refurbish, or recycle.
It optimizes a product's end-of-life system, enabling users to make products more serviceable, maintainable, and repeatable.

Benefits of Design for Disassembly

Enables rapid and economical disassembly
Reduces the number of assembly operations
Ensures product service life is appropriate
Allows for modular product design, enabling modules to be disassembled for service or reuse
Reduces the number of parts used in an assembly
Enables standardization of component assembly material priority
Reduces the number of different types of material in an assembly

Design for Disassembly Factors

Product Structure

Create a modular design
Minimize component count
Optimize component standardization
Minimize product variants

Materials

Minimize the use of different materials
Use recyclable materials
Eliminate toxic or hazardous materials

Fasteners, Joints, and Connections

Minimize the number of joints and connections
Make joints visible and accessible
Eliminate hidden joints
Use joints that are easy to disassemble
Mark non-obvious joints
Use fasteners rather than adhesives

Characteristics of Components for Disassembly

Good accessibility
Low weight
Robust, minimize fragile parts
Non-hazardous
Preferably unpainted

Disassembly Conditions

Design for automated disassembly
Eliminate the need for specialized disassembly procedures
Use simple and standard tools for disassembly

Importance of Product Disassembly

Product disassembly is becoming an important phase of the product lifecycle
It considers environmental and economic points of view
