Study Notes
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
