Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for connecting formwork beams, such as nailing and manual clamping, are laborious, deteriorate the beams, and lack consistent clamping pressure, making it difficult to quantify the strength of the joint and requiring significant manpower for assembly and disassembly.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If nailing is used to connect wooden I-beams, then the beams can be joined together, but the service life of the beams is shortened due to deterioration caused by nails and disassembly/removal processes
Solution Approach 1:
The invention extracts the harmful nails from the connection system and replaces them with a clamp-based mechanism. The clamp applies pressure to hold the beams together without penetrating or damaging the beam structure, thereby preserving the beams' service life while eliminating the deterioration caused by nail insertion and removal.
Solution Approach 2:
The clamp acts as an intermediary element between the two beams, providing a non-invasive connection method. Instead of directly fastening the beams with nails that cause damage, the clamp mediates the connection by applying external pressure, thus avoiding the harmful effects of nail-induced deterioration.
2Ease of manufacture
If manual clamping with threaded bolts and clamping nuts is used, then beams can be connected, but considerable manpower is required for assembly and disassembly
Solution Approach 1:
The clamp is designed with a self-service mechanism that allows automatic engagement and locking when placed over the beam intersection. The spring-loaded or elastic structure automatically adjusts to apply the necessary clamping force without requiring manual tightening of bolts or nuts, significantly reducing the manpower needed for assembly and disassembly while maintaining secure connections.
Solution Approach 2:
The clamp incorporates dynamic elements such as springs or elastic materials that automatically adjust the clamping force based on the beam dimensions and load conditions. This dynamic adjustment eliminates the need for manual calibration and tightening operations, reducing labor requirements while ensuring consistent connection quality.
3Reliability
If threaded bolts and clamping nuts are used for connection, then beams can be secured, but the clamping pressure varies due to manual operation discretion
Solution Approach 1:
The clamp incorporates a feedback mechanism through its spring-loaded or elastic structure that automatically senses and adjusts to the beam dimensions and load conditions. The spring force provides continuous feedback, automatically maintaining consistent clamping pressure regardless of variations in beam size or external loads, eliminating the pressure variability caused by manual tightening differences.
Solution Approach 2:
The clamp design utilizes parameter changes in the spring or elastic material to automatically adjust the clamping force. As the spring compresses or extends in response to beam dimensions and applied loads, it dynamically adjusts the clamping pressure to maintain optimal connection stability, ensuring consistent performance without manual intervention.
