Problem Breakdown• The wood-based material of pipe was leaking and damage

after 1 month of operation.

• Caused by the transported material knocked and rubbed onto the inside of the pipe.

• The pipe system using water as medium of transportation.

• The pipe is 1 meter long.

1 meter

PART 2

Objective

To prevent the pipe damage caused by the transported material

To ensure the transported materials are not ruined

To ensure the operation goes smoothly

Benefits/Impact if the Problem Solved

• Could reduce the monthly cost for pipe replacement.

• The time consuming for the pipe replacement can be eliminated.

• Save the energy needs to replace the pipe.

• Reduce the possibilities for the transported material to be ruined from the knocking and rubbing.

Cause & Effect Chain Analysis

Pipe leaking and damage

Being knocked and rubbed by the transported material

The material has sharp-pointed edge

The pipe thickness is too thin

High speed of the water stream

TOOL 1: ENGINEERING CONTRADICTION

“If the sharp-pointed edge on the material is reduced and the thickness of the pipe is increased, then it will prevent the pipe from leaking and damage after 1 month of operation.”

Improving: #33 Ease of operation, #14 StrengthWorsening: #12 Shape

POTENTIAL SOLUTIONPrinciple 30: Flexible shells and thin films

• To isolate the material from being directly contact with the pipe• Use a thin layer of flexible shells made from rubber• Laminate the thin layer of rubber at the interior part of the

pipe.Pipe Interior

Rubber sheets

TOOL 2: SUFIELD MODEL• Harmful sufield between material and pipe• Add F(chemical) to reduce the F(mechanical) impact of knocking of material to the

pipe which increase bouyancy of material by air bubble formed by the inert chemical
