Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drop head support devices for formwork beams face challenges in achieving inclined planes without using wooden wedges, which are labor-intensive, costly, and limited by wood's strength and durability, and require multiple wedges for varying inclinations, leading to instability during assembly.
Innovation Solution
A drop head support device with mirror-symmetrical V-shaped recesses and a planar side wall for variable beam support, allowing for adjustable inclination without wedges, featuring a cylindrical pin for connecting plates and an engagement element for secure prop coupling, enabling stable and rapid beam positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wooden wedges are used to achieve inclined planes, then different inclinations can be obtained, but labor deployment increases and wood consumption increases
Solution Approach 1:
The recesses are designed with contoured side walls that allow the supporting beam to be positioned at various inclinations by sliding along the curved surface. This dynamic positioning capability eliminates the need for multiple fixed-angle wooden wedges, enabling continuous inclination adjustment without additional labor or material consumption.
Solution Approach 2:
The geometry of the recesses is specifically designed with contoured side walls that provide variable geometric parameters (inclination angles) along the curve. By changing the position of the beam along this contoured surface, different inclination parameters are achieved without requiring multiple discrete wedge components, thereby improving productivity.
2Adaptability or versatility
If wooden wedges are used to achieve inclined planes, then different inclinations can be obtained, but wood consumption increases
Solution Approach 1:
The contoured side walls of the recesses enable dynamic positioning of the supporting beam at various inclinations. This eliminates the need for multiple disposable wooden wedges, reducing wood consumption while maintaining full adaptability for different inclination requirements.
Solution Approach 2:
The single support device with contoured recesses serves multiple functions by accommodating beams at various inclinations. This universal design replaces the need for multiple specialized wooden wedges for different angles, thereby reducing overall wood consumption while maintaining versatility.
3Adaptability or versatility
If wooden wedges are used to achieve inclined planes, then inclination adjustment is possible, but system stability decreases during assembly
Solution Approach 1:
The contoured side walls provide a continuous curved surface that guides the beam into stable equilibrium positions at various inclinations. The geometry of the contours ensures that the beam naturally settles into stable positions during assembly, eliminating the instability associated with manual wedge placement while maintaining inclination adjustability.
4Stability of the object's composition
If conventional recesses with vertical side walls are used, then beam containment is achieved, but inclination adjustment is limited
Solution Approach 1:
The side walls transition from vertical to contoured, creating a dynamic surface that allows the beam to slide and settle at various inclinations. The contoured geometry maintains containment stability through its curved profile while enabling continuous inclination adjustment, combining both requirements in a single structure.
