Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a contactless measuring member is used, then measurement capability is improved, but the device becomes bulkier and harder to handle
Solution Approach 1:
The measuring device is divided into separate components: the interface body that attaches to the articulated arm, and interchangeable grip members that can be selected based on measurement needs. This segmentation allows the bulkier contactless measuring member to be separated from the handling portion, improving ease of operation while maintaining measurement capability.
Solution Approach 2:
A tubular coupling part with a locking mechanism serves as an intermediary between the interface body and the grip member. This coupling mechanism provides a secure connection point that allows precise positioning of the measuring member while enabling easy attachment and detachment of different grip types, thus resolving the contradiction between measurement precision and handling ease.
2Reliability
If a secure attachment mechanism is implemented, then reliability of connection is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is designed to automatically lock the grip member to the interface body through a tab that engages with the tubular coupling part when the grip member is inserted. This self-locking feature provides reliable connection security without requiring additional manual locking steps or complex control systems, thus maintaining simplicity while ensuring reliability.
3Adaptability or versatility
If interchangeable grip members are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The interface body with the standardized tubular coupling part serves as a universal mounting platform that can accommodate different types of grip members (contactless measuring members, contact measuring members, or other accessories). This universal interface design provides adaptability for multiple measurement functions while keeping the base interface body simple and unchanged, thus managing system complexity effectively.
