Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional sealing members are used for formwork panels, then sealing function is provided, but the ability to create angled or chamfered edges is lost
Solution Approach 1:
The patent combines the sealing member and negative formwork into a single integrated component. The sealing member includes a sealing zone for hydraulic sealing and a negative formwork zone for creating angled edges, merging two previously separate functions into one versatile element that eliminates the need for additional lost formwork.
Solution Approach 2:
The sealing member is designed to perform multiple functions: it provides hydraulic sealing at the interface between formwork panels and simultaneously creates negative impressions for angled or chamfered edges in the molded construction element. This multi-functional design eliminates the need for separate sealing and formwork components.
2Adaptability or versatility
If separate negative formwork profiles are added to create angled edges, then edge treatment capability is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent integrates the negative formwork zone directly into the sealing member structure. The negative formwork zone is formed as an integral part of the elongated profile, eliminating the need for separate negative formwork profiles and simplifying the overall formwork assembly.
Solution Approach 2:
The sealing member serves as both the sealing element and the negative formwork element, providing a universal solution that eliminates the need for multiple specialized components and reduces assembly complexity.
3Adaptability or versatility
If lost formwork materials like cardboard or polystyrene are used to create angled edges, then edge shaping capability is improved, but reusability and environmental sustainability are worsened
Solution Approach 1:
The patent employs a reusable sealing member made of durable material that can be recovered and reused across multiple formwork cycles. Unlike disposable lost formwork materials, this sealing member maintains its functionality after concrete pouring and can be cleaned and reused, eliminating waste generation.
Solution Approach 2:
The sealing member is made from a durable material that can withstand the concrete pouring process and be reused. The material properties are selected to provide both sealing functionality and negative formwork capability while maintaining reusability, changing the parameter of material durability from temporary to permanent.
4Reliability
If multiple separate components are used for sealing and formwork functions, then functional specialization is improved, but ease of manufacture and cost-effectiveness are worsened
Solution Approach 1:
The patent combines the sealing function and negative formwork function into a single molded elongated profile. This integration reduces the number of parts that need to be manufactured, stored, and assembled, thereby reducing manufacturing costs and improving ease of manufacture while maintaining both functions.
Solution Approach 2:
The sealing member is designed as a universal component that performs both sealing and negative formwork functions, eliminating the need for multiple specialized components and reducing overall manufacturing complexity and cost.

AI summary
The invention relates to a formwork panel (1) for manufacturing a building element by casting a hydraulic filling material. It comprises, in at least one of its bearing faces (FA), a housing (3) for receiving a sealing element (10) via a mounting area (15). This sealing element (10) comprises a joint area (19) arranged to deform elastically and ensure contact sealing at a joint plane (J) between said formwork panel (1, 2) and another adjacent formwork panel, and a negative formwork area (21) arranged to create an imprint in said molded building element. The sealing element (10) is reversible and can adopt a first mounting position in which said negative formwork area is retracted inside the formwork panel, and a second mounting position in which it protrudes outside the formwork panel to create said imprint.
