Auxiliary tool
Brain Maier Azhou used a walking aid on the campus on the 9th. The screw of the joint of the appliance suddenly broke, causing his center of gravity to fall to the ground. The teacher on the side was scared and the mother reflected to the manufacturer. The other party was sloppy and said: "I want to send you a few screws!" The mother of Azhou pointed out that the company called the manufacturer the next day, only asked for a few screws, and did not care whether the child was injured or not, but did not pay attention to the safety of the product itself; For a child with limited mobility, the safety is on the walker, and the manufacturer does not care if the screw is broken. "The attitude is too sloppy!"
According to the reporter's inquiry, the senior commissioner of the manufacturer said that the screw fracture condition does not occur often. Because the screw belongs to a large number of products, when the original purchase is made to the manufacturer, the other party does not dare to guarantee that there will never be a problem; the actual situation will be found and the problem will be identified. Reasons, including problems with angle of use, load-bearing pressure points, or materials.
The Yilan County Auxiliary Resource Center believes that there is a problem with the design of this product. The manufacturer is required to pay special attention to the selection of parts. The foreign products use 8 mm diameter screws. The screws in this case are 6 mm, and the screw turning is also different. The screw is the whole car screw, and the rigidity is not as good as the screw with the nut only. The auxiliary equipment resource center emphasizes that the screw break is difficult to prevent, and it can not be seen from the appearance. However, the management of domestic medical equipment is loose, and the manufacturer is not forced to test the product, which causes the manufacturer to pay no attention to the safety of product design. It is considered that the screw is broken and the normal state is caused. The safety of the auxiliary equipment is insufficient, which is the main cause of the accident.
