Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional measuring devices face challenges in efficiently attaching and detaching measuring members, handling flexibility, and user interface usability, particularly when dealing with bulky or heavy measuring members.
Innovation Solution
A three-dimensional measuring device with an articulated arm structure featuring a fastener mechanism controlled by a lever, allowing the measuring member to be selectively snap-fastened, locked, or released, along with a tubular handle design for improved grip and interchangeable handles, and a locking mechanism for secure attachment and easy removal of measuring members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional fastening mechanism is used to attach the measuring member to the interface body, then the connection is secure, but the attachment and detachment process becomes time-consuming and complex
Solution Approach 1:
The fastening mechanism is divided into separate functional components: a fastener element on the measuring member and a corresponding receptacle on the interface body. This segmentation allows the measuring member to be quickly attached by simply engaging these separate elements, and quickly detached by releasing them, without requiring complex multi-step fastening procedures.
Solution Approach 2:
The fastening mechanism incorporates a movable fastener element that can transition between engaged and disengaged states. This dynamic design allows the measuring member to be rapidly attached and detached through simple linear movement of the fastener, eliminating the need for time-consuming manual fastening operations while maintaining secure connection during measurement.
2Adaptability or versatility
If the measuring member is permanently fixed to the interface body, then the connection is stable, but the flexibility to interchange different measuring members is lost
Solution Approach 1:
The fastening mechanism uses a movable fastener element that can be easily engaged and disengaged, enabling quick interchange of different measuring members while ensuring stable connection during use. The dynamic nature of the fastener allows it to transition between attached and detached states without compromising connection reliability when engaged.
Solution Approach 2:
The interface body is designed with a universal receptacle that can accommodate different types of measuring members through standardized fastening interfaces. This universality allows various measuring members to be interchanged on the same interface body, providing flexibility and adaptability while maintaining reliable connections through the consistent fastening mechanism.
3Adaptability or versatility
If a simple attachment mechanism is used, then the interchangeability is improved, but the security and stability of the connection during measurement is compromised
Solution Approach 1:
The attachment mechanism is segmented into distinct fastener and receptacle elements that work together to provide both ease of interchange and strong connection. The simple geometric forms of these segmented components enable quick engagement and disengagement, while their precise fit and interlocking features ensure strong, stable connection during measurement operations.
Solution Approach 2:
The dynamic fastener element provides a simple yet effective attachment mechanism that balances ease of interchange with connection strength. The fastener can be quickly engaged and disengaged for easy interchangeability, while its design ensures sufficient connection strength and stability during measurement through proper geometric configuration and material selection.
4Adaptability or versatility
If the handle is fixed to the interface body, then the structural integrity is maintained, but the ability to replace handles for different applications is limited
Solution Approach 1:
The handle is segmented as a separate, interchangeable component with its own fastening mechanism involving a fastener element and receptacle. This segmentation allows handles to be easily replaced for different applications without compromising the structural integrity of the main interface body, while keeping the attachment mechanism relatively simple through standardized fastening interfaces.
Solution Approach 2:
The interface body incorporates a universal receptacle design that can accommodate different handle types through standardized fastening interfaces. This universality enables handle interchangeability for different applications while maintaining structural integrity, and the consistent fastening mechanism keeps the overall device complexity manageable despite the added versatility.

AI summary
A three-dimensional measuring device, comprising an arm having a free end provided with an interface body carrying a measuring member and a grip member enabling an operator to point the measuring member at a zone of the object that is to be measured. The measuring member includes a connector to be electrically connected to a corresponding connector of the interface body by a fastener mechanism that is controllable by a lever and that is arranged in such a manner that the lever controls the fastener mechanism to occupy selectively a snap-fastening state in which the measuring member is held on the interface body while the connectors are disengaged from each other, a locking state in which the measuring member is fastened to the interface body and the connectors are engaged with each other, or a release state in which the measuring member can be separated from the interface body.
