How To Design Parts That Can Be Easily Picked Up

During assembly, operators frequently complained that some parts were difficult to pick up, either because they were too small or too heavy, resulting in reduced assembly efficiency. How can designers improve this to make parts easier for operators to handle? Here is some advice:

1.  Parts shall not be either too small or too heavy, too slippery or too viscious

Parts should be designed with appropriate dimensions so that operators or robotic arms can easily grasp and assemble them. If parts are not too small or too heavy, the assembly process will be smoother and more efficient. Otherwise, special auxiliary tools may be required to assist in picking up the parts, which can significantly reduce assembly efficiency.

2.  Design a special trait for easy catch

If parts are difficult to pick up due to their dimensions, additional features such as edgefolds can be incorporated into the design. In the graphic below, the parts were too thin to be easily grasped and assembled in the original design. In the improved design, an edgefold was added, making the parts much easier to pick up and assemble.

3.  Parts shall have no sharp edges or angles

Special attention should be given to the following issues. First, parts should not have sharp edges or angles, as they can harm operators or consumers. Additionally, sharp edges or angles can damage the appearance or crucial components of other products. Therefore, designers should modify sharp edges or angles to be rounded in their designs.
