Patent number: 11390019Abstract: An additive manufacturing method and an object manufactured thereby are disclosed. The object includes a first component and a second component pivotally connected to each other through a rotation shaft. A first engaging element of the first component and a second engaging element of the second component spatially correspond to each other. When the object is manufactured in a manufacturing space, the first component is close to the second component, and the first engaging element and the second engaging element are disengaged with each other. After the object is manufactured, the first component is rotated relative to the second component at an adjustment angle around the rotation shaft. The first engaging element and the second engaging element are engaged with each other and locked, to form a use space of the object larger than the manufacturing space. It is beneficial to achieve the purpose of reducing the required manufacturing space.Type: GrantFiled: December 20, 2019Date of Patent: July 19, 2022Assignee: TECO IMAGE SYSTEMS CO., LTD.Inventors: Ming-Chieh Chung, Ting-Chun Chen

Patent number: 10257378Abstract: The disclosure is related to a positioning module and a handheld scanner using the same. The positioning module includes a base, a rotation support member, a shaft body, a wheel, a first sensor, and a second sensor. The rotation support member is pivoted to the base and rotates relative to the base about the first axis. The shaft body and the wheel are pivotally contacted to the main body and in constant contact with each other. When the wheel is rotated about a second axis due to a frictional force, the main body displace linearly and the shaft body is driven to rotate. Since the second axis is offset by the first axis, the rotation support member is driven to rotate at an angular displacement synchronously. The first and second sensors detect the shaft body and the main body to obtain the linear and angular displacements for positioning.Type: GrantFiled: December 15, 2017Date of Patent: April 9, 2019Assignee: TECO IMAGE SYSTEMS CO., LTD.Inventor: Ming-Chieh Chung
