Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional clamp is used to connect ledger to shoring post, then the connection is secure, but the assembly and disassembly process is time-consuming and inefficient
Solution Approach 1:
The clamp incorporates a rotatable member that can rotate between a first position (for assembly) and a second position (for locking). This dynamic element allows the clamp to transition between different functional states, enabling quick assembly by simply rotating the member without requiring complex manipulation of multiple components.
Solution Approach 2:
The wedge is extracted as a separate, removable component from the clamp body. This allows the wedge to be easily inserted and removed to engage or disengage the locking mechanism, significantly reducing the time required for assembly and disassembly operations while maintaining secure connection when locked.
2Ease of operation
If the clamp design is simplified for easy assembly, then the assembly efficiency improves, but the connection strength and stability may be compromised
Solution Approach 1:
The clamp is divided into distinct functional segments: a base member for structural support, a rotatable member for operation, and a wedge for locking. This segmentation allows each component to be optimized for its specific function while working together to provide both ease of assembly and strong connection.
Solution Approach 2:
The rotatable member features a curved surface that interfaces with the wedge, allowing smooth rotational motion. The curved geometry enables the operator to easily rotate the member through a limited arc to engage or disengage the clamp, reducing operational effort while maintaining secure locking when engaged.
3Adaptability or versatility
If the clamp accommodates various shoring post sizes, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The clamp base member is designed with a universal geometry that can accommodate multiple shoring post diameters. The opening and closing mechanism works effectively across a range of sizes without requiring adjustment or different clamp models, providing multi-functionality in a single device design.
Solution Approach 2:
The clamp utilizes parameter changes in the form of the wedge angle and rotatable member curvature to maintain adaptability across different post sizes. By optimizing these geometric parameters, the clamp can effectively engage various diameters while keeping the overall structure relatively simple.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clamp provides a strong and stable connection between ledgers and shoring posts, enhancing the stability of shoring decks and facilitating safer and more efficient construction processes by allowing easy installation and removal of ledgers without disturbing the existing shoring posts.
Implementation Method 1
a wedge including a bottom end and a top end. The bottom end of the wedge is configured to be inserted into the slot of the base member. When the wedge is inserted into the slot of the base member at a first engage position, the wedge registers the rotatable member in a first lock position. When the wedge is inserted further into the slot of the base member at a second engage position, the wedge registers the rotatable member in a second lock position.
Implementation Method 2
The first end of the rotatable member is configured to be inserted into the base member and be rotatable and slidable in the base member along a longitudinal axis of the rotatable member.
Implementation Method 3
a slot in the rotatable member that engages with a pin in base member and automatically forces the rotation of the rotatable member along its longitudinal axis

AI summary
The disclosure is directed to a clamp for connecting a ledger to a shoring post. The clamp includes a base member, a ledger-connecting member, and a first jaw, which are fixed connected to each other. The clamp includes a rotatable member inserted into the base member, which is rotatable and slidable in the base member along a longitudinal axis. A portion of the rotatable member is accessible via the slot of the base member. The clamp includes a second jaw fixedly connected to the rotatable member. The clamp further includes a wedge, and when the wedge is inserted into the slot of the base member to engage the rotatable member in a lock position, the first and second jaws are locked to capture two sides of a shoring post.
