Key Findings

01Non-value-added activities in regular component changeovers were reduced by up to 41%, with an elimination of time by 41.6%.
02Non-value-added activities in new item changeovers were reduced by 36.6%, with an elimination of time by 53.3%.

Application

Design takeaway

How to apply

Analyze your own production or assembly processes to identify bottlenecks related to searching for tools or components. Consider using TRIZ principles to brainstorm innovative solutions for organizing equipment and materials, and implement 5S principles to maintain an orderly workspace.

Project actions

01When identifying a problem, clearly define the 'changeover' activity and what constitutes 'non-value-added' time within it.
02Document the 'before' state thoroughly, including photos and time studies, to provide a strong baseline for comparison.

Method & Evidence

AimHow can a TRIZ-method-informed equipment rack design, combined with 5S principles, reduce searching and transportation time during changeover activities in a furniture assembly plant?

MethodCase Study

ProcedureThe study involved analyzing the root causes of increased work-in-process due to component shortages, identifying the router section as a constraint. A messy workspace and misplaced devices were found to cause non-value-added activities. A new equipment rack was designed using the TRIZ method, and the 5S methodology was implemented. The impact on changeover times for regular and new components was measured before and after the intervention.

ContextFurniture assembly manufacturing plant

Variables

IVImplementation of TRIZ-designed rack and 5S methodology

DVTime spent on non-value-added activities during changeover (searching, transportation)

CVType of components being changed over, general workflow of the assembly section, tools and machinery used.

Strengths & Limitations

Strengths

+Clear identification of a specific problem (increased changeover time) and its root causes.
+Application of a systematic innovation tool (TRIZ) for design.
+Quantifiable results demonstrating the impact of the design intervention.

Limitations

The effectiveness of TRIZ depends on the user's understanding and application of its principles. The 5S implementation also requires ongoing commitment from the workforce.

Reliability & validity

The study's reliability could be enhanced by repeating the measurements over a longer period to account for learning effects or variations in workflow. Validity is supported by the clear definition of non-value-added activities and the quantitative measurement of time savings.

Think critically

To what extent are the observed time savings attributable to the TRIZ-designed rack versus the implementation of the 5S methodology, and could similar results be achieved with a simpler organizational approach?

Design Principles

"Optimize physical layout and accessibility to minimize non-value-added search and transportation time in production processes."

This research demonstrates a practical application of systematic innovation tools to address a common manufacturing bottleneck: inefficient changeover times. By optimizing the physical arrangement and accessibility of tools and components, design interventions can directly impact operational efficiency and reduce waste.

What This Means for Your Design

Using a structured method called TRIZ to design a better rack for tools and parts helped a furniture factory save a lot of time when switching between making different products.

How to use in your project
