Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional anchor devices are used for shoring walls, then the structure provides sufficient strength and stability, but the device requires two-handed operation and can jam gloves, reducing ease of operation
Solution Approach 1:
The patent combines the closing part, locking part, and connecting part into a single integrated slider component that moves along guide surfaces within the body. This merging of multiple functions into one component enables one-handed operation while maintaining structural strength, as the slider simultaneously performs closing, locking, and connecting functions through its movement along the guide surfaces.
Solution Approach 2:
The patent introduces guide surfaces as intermediary elements that constrain the movement of the slider. These guide surfaces act as mediators between the slider and the body, ensuring controlled motion and preventing glove jamming by directing the slider along predetermined paths. This intermediary mechanism enables easy one-handed operation while maintaining device integrity.
2Ease of operation
If traditional anchor devices are used, then the device can be securely attached to shoring walls, but significant force is required to open and close the device, increasing operational difficulty
Solution Approach 1:
The patent replaces traditional complex mechanical locking systems with a sliding mechanism that utilizes guide surfaces and spring-loaded locking parts. The slider moves along guide surfaces to engage or disengage locking parts, which are biased by springs. This substitution reduces the force required for operation while maintaining secure attachment through the interplay of mechanical guidance and spring forces.
Solution Approach 2:
The patent introduces dynamic elements including springs that bias the locking parts and a movable slider that transitions between locked and unlocked positions. The spring-loaded locking parts automatically engage when the slider moves to the closed position, providing secure attachment without requiring significant closing force. The dynamic nature of the system allows easy opening by overcoming the spring bias.
3Ease of operation
If the device uses a sliding mechanism with multiple parts, then one-handed operation is enabled, but the device complexity increases with more components
Solution Approach 1:
The patent merges the closing part, locking part, and connecting part into a single integrated slider component. This consolidation reduces the number of separate components while enabling thumb-operable functionality. The slider's movement along guide surfaces simultaneously achieves closing, locking, and connecting actions, thereby simplifying the overall device structure despite the sophisticated operation mechanism.
4Ease of operation
If the closing part is made movable to enable operation, then ease of operation is improved, but the risk of uncontrolled opening increases
Solution Approach 1:
The patent replaces uncontrolled movable closing mechanisms with a guided sliding system. The slider is constrained to move along predetermined guide surfaces, ensuring controlled motion. Spring-loaded locking parts automatically engage when the slider reaches the closed position, preventing uncontrolled opening. This mechanical substitution maintains movability for operation while ensuring reliability through guided control and automatic locking.
Solution Approach 2:
The patent implements a feedback mechanism where the position of the slider along the guide surfaces automatically triggers the engagement or disengagement of locking parts. When the slider moves to the closed position, the spring-loaded locking parts automatically engage, providing feedback-based control that prevents uncontrolled opening. This feedback system ensures that movability is maintained while reliability is enhanced through automatic position-dependent locking.

AI summary
The anchoring device for shuttering walls includes a body containing an arm with a top tab, a fastening part for at least one connector, a moving closing part mounted in the body and pressed to the closed position at rest, and a locking part. The closing part is a sliding part with an indentation on one of its lateral surfaces which is matched with the slider lock in the open position of the device, and with pass-through pockets and a bottom tab, forming, together with the arm and the upper tab of the body, a tong closure assembly. The device has a set of springs, of which one pushing spring is located inside the body directly above the slider lock and is secured from above by a pressure screw. The three compression springs are located inside the body in the pass-through pockets of the slide.
