Designing an interlocking workbench

Project Info


Our Company was requested to make a portable, interlocking manufacturing bench concept into a design. The client was a manufacturing company with a lot of workbenches in the main working area of the company. They had the problem of daily cleaning of this area which was full of working tables that were obstacles to the cleaning operation. Therefore, they came up with the idea of making a design for a movable interlocking table that could be easily moved during the cleaning operation, and returned to its initial location and locked with the other tables.

The design was intended to be later discussed with a potential investor who was willing to make an investment in its production.


The main requirements for the project included the followings:

  1. The table was to be easily movable
  2. The design had to implement a locking mechanism so that tables could be locked together during the work.
  3. The size of the larger fixed table was to be 39″ x 72″ (99cm x 182 cm)
  4. A moveable utility peg table was to be installed in the middle of the large table with the size of 15” x 24” (38cm x 61cm)
  5. The width of the larger workbench structure was to be 8″ (20.3cm) on the left side (which would accommodate the computer holder) 42″ (106.7cm) in the middle (to accommodate the smaller table) and 22″ (55.9cm) on the right side to accommodate shallow depth tool drawers and a deeper equipment drawer.
  6. Also, a video clip of the table showing its main features was requested.


The design team took the idea and worked on the draft design. Since the design involved working with a few people remotely to understand the requirements and creating the initial drawing in order to refine the concept, a lot of communication was made before all the requirements were clearly realized.

Having worked out a detailed memorandum of understanding with the client on every aspect of the work, the design team initiated making a draft design and submitting to the client. After some modifications on the initial design, the final design was made. Some of the main features of the design included the following:

  1. A frame material was instead of the tubing as it could better accommodate shelves, parts bin holders, power strips, etc.
  2. Due to the locking feature or the tables, the four wheels of the bigger table were selected to be ordinary wheels, whereas, the wheels for the smaller table were chosen to be lockable to fix it during the work.
  3. A movable light holder cover was added to the top of the design for fixing the needed light for each table.
  4. Finally, a video clip was made containing all features of the design. The video clip was to be later delivered to the investor of the product.

The final design took about 3 weeks to get completed. Due to the client’s request for some modifications on the size and shape of the cabinet, it took more time compared to the initial schedule as some details had to be worked out. At the end of the project, an animation of the project was made and the final package was delivered to the client. The client was quite satisfied as all his requirements were met, and he made the following feedback:
“Thank you again for the excellent work… Both Mike and I are very pleased with the animation”
