Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If deck slab brackets are interconnected by longitudinal struts and transverse struts to prevent folding or pivoting, then the stability and reliability of the supporting device is improved, but the device complexity and ease of operation deteriorate due to the complex scaffolding tube assembly that requires considerable mounting and removal effort
Solution Approach 1:
The patent extracts the essential stabilization function from the complex scaffolding tube assembly. Instead of using multiple interconnected struts forming a rigid framework, the invention employs a single rotation-reducing element that performs the critical function of preventing bracket rotation while eliminating the need for complex assembly and disassembly operations.
Solution Approach 2:
The patent segments the stabilization function into a separate, dedicated component (the rotation-reducing element) that can be independently attached to the deck slab bracket. This element works in conjunction with the lowering device to prevent rotation, allowing the main bracket structure to remain simple while achieving the required stability.
2Reliability
If scaffolding tube assemblies are used to stabilize deck slab brackets, then the reliability is improved, but the productivity and ease of operation worsen due to considerable operating time and costs for mounting and removing
Solution Approach 1:
The invention extracts the essential stabilization function from the complex scaffolding tube assembly. Instead of using multiple interconnected struts forming a rigid framework, the invention employs a single rotation-reducing element that performs the critical function of preventing bracket rotation while eliminating the need for complex assembly and disassembly operations.
Solution Approach 2:
The rotation-reducing element is designed to be pre-assembled with the lowering device or easily attached thereto before being mounted on the deck slab bracket. This preliminary preparation allows for rapid installation without requiring time-consuming on-site assembly of complex scaffolding structures, thereby improving productivity while maintaining reliability.
3Reliability
If a rotation-reducing element is added to the supporting device, then the reliability is improved by counteracting torque, but the device complexity increases
Solution Approach 1:
The patent merges the rotation-reducing element with the lowering device by attaching the rotation-reducing element to the lowering device. This integration combines two functional components into a unified assembly that reduces overall device complexity while maintaining the torque counteracting function. The merged structure eliminates the need for separate mounting operations and simplifies the overall supporting device architecture.
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 solution effectively reduces the effort and cost of mounting/removing scaffolding, prevents folding or pivoting of the supporting device, and accelerates the construction process without compromising stability, as the rotation-reducing element counteracts torque efficiently.
Implementation Method 1
a movement force component acts on the deck slab bracket in the movement direction of the slab formwork as a result of friction between the slab formwork and the deck slab bracket
Implementation Method 2
This torque can cause the deck slab bracket to rotate relative to the side wall

AI summary
A supporting device for the construction industry. Said device has a fixing element which rests against a side wall and is fixed at a fixing point of the side wall. Said device also has a cantilever which is connected to the fixing element and, when the fixing element is in the fixed state, projects from the side wall such that a load element can rest against a bearing point of a bearing element of the cantilever. The load element can now be displaced in a displacement direction substantially parallel to the side wall relative to the cantilever and, when the load element rests against the bearing element of the cantilever, the cantilever is coupled to the load element such that a displacement force component acts on the cantilever in the displacement direction when the load element is displaced, said displacement force component resulting in a torque on the cantilever.
