Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional formwork dummies, such as telescopic and adjustable mannequins, face issues like irregular surface finishes and increased storage and transportation complexities due to multiple sizes and parts, leading to higher costs and labor times in constructing buildings with poured concrete structures.
Innovation Solution
A modular formwork dummy with corner elements, junction elements, and rotatable wedges that allow for adjustable dimensions without discontinuities, reducing the need for multiple sizes and minimizing part loss during transport, featuring a shaft and wedges that move between filling and retracted positions for smooth surface creation and easy handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telescopic elements are used in formwork dummies, then the dimensions can be adjusted to different sizes, but the surface finish becomes irregular due to discontinuities in the molding surface
Solution Approach 1:
The formwork dummy is divided into modular components: corner elements, connecting elements, and intermediate elements. Each component has standardized finishing faces that ensure continuous, regular surface finishes when assembled. This segmentation allows dimensional adjustment through assembly configuration rather than telescopic mechanisms, maintaining surface regularity while achieving adaptability.
2Manufacturing precision
If multiple fixed-size mannequins are used to create different opening sizes, then each size can be precisely formed, but storage space requirements increase significantly
Solution Approach 1:
The dummy is segmented into standardized corner and connecting elements that can be reconfigured to create multiple opening sizes. This modular approach allows a single set of components to replace multiple fixed-size dummies, significantly reducing storage space while maintaining precision through standardized finishing faces and dimensions.
Solution Approach 2:
The modular components serve multiple functions: corner elements can be positioned at different locations, connecting elements can be arranged in various configurations, and intermediate elements can be added or removed. This universality allows the same components to create multiple different opening sizes, eliminating the need for separate fixed-size dummies for each application.
3Adaptability or versatility
If independent intermediate elements are used to adjust mannequin dimensions, then various sizes can be achieved, but the risk of losing parts during transport increases
Solution Approach 1:
Intermediate elements are designed to nest within the corner elements or connecting elements when not in use. This nesting arrangement keeps all components organized and contained within a compact space during transport and storage, eliminating the risk of losing independent intermediate elements while maintaining the ability to assemble various configurations.
4Area of stationary object
If adjustable mannequins with multiple components are used, then storage space is reduced, but the complexity of assembly and transportation increases
Solution Approach 1:
The dummy is segmented into standardized corner and connecting elements with uniform connection mechanisms. This standardization simplifies assembly procedures despite the modular nature, as each component interfaces with others through consistent connection methods. The segmentation into manageable modules actually reduces complexity compared to trying to transport and store multiple complete fixed-size dummies.
