Engineering Contradiction Analysis
1Strength
If conventional joint profiles are used, then the joints can be sealed to some extent, but the profiles lack sufficient tensile and restoring forces, leading to inadequate sealing and potential cracking under temperature fluctuations and traffic loads
Solution Approach 1:
The joint profile is divided into multiple side arms (at least two) that extend from the main web, with connecting webs linking these side arms to each other and to the main web. This segmentation creates a structured framework that distributes and withstands tensile forces more effectively while maintaining sealing capability through the coordinated deformation of individual segments.
Solution Approach 2:
The invention introduces a multi-dimensional geometric configuration with side arms extending in transverse directions and connecting webs creating spatial relationships between them. This three-dimensional arrangement enables the profile to resist displacement in multiple directions simultaneously while maintaining restoring forces through the geometric interplay of its components.
2Adaptability or versatility
If conventional joint profiles are used, then they can accommodate joint movements, but they exhibit virtually no dimensional stability and can potentially lead to twisting of the profile
Solution Approach 1:
The profile is segmented into side arms and connecting webs that can deform independently yet remain coordinated. This allows the structure to adapt to joint movements through controlled deformation of individual segments while the overall geometric configuration maintains dimensional stability and prevents twisting.
Solution Approach 2:
The joint profile combines multiple geometric elements (main web, side arms, connecting webs) into a composite structural system. This composite configuration integrates the flexibility needed for joint movement accommodation with the stability required to prevent twisting, as each component contributes different mechanical properties to the overall structure.
3Ease of operation
If the joint profile is made sufficiently flexible and deformable to allow slab mobility, then cracking can be prevented, but the profile may sag or tear out of the joints under traffic loads
Solution Approach 1:
The multi-dimensional geometric configuration with side arms extending in transverse directions and connecting webs creates a structurally stable framework. This spatial arrangement enables the profile to deform flexibly in response to slab movements while the geometric interlocking and distributed force paths prevent sagging and tearing out under traffic loads.
Solution Approach 2:
The segmented structure with multiple side arms and connecting webs allows localized deformation at critical points while maintaining overall structural integrity. This segmentation enables slab mobility through controlled flexibility in specific regions while other parts of the profile maintain strength to resist displacement under load.
4Strength
If the joint profile is made rigid to withstand traffic loads and prevent sagging, then displacement resistance is improved, but the profile becomes less flexible, restricting slab mobility and potentially causing cracks
Solution Approach 1:
The segmented architecture with side arms and connecting webs creates a structure that is rigid in certain aspects (resisting displacement under load) while flexible in others (accommodating slab movements). Each segment can deform independently to allow slab mobility while the overall configuration maintains strength through its geometric framework.
Solution Approach 2:
The joint profile employs a dynamic geometric configuration where the relative positions and orientations of side arms and connecting webs can change in response to applied forces. This dynamic structure adapts its stiffness characteristics based on loading conditions, providing rigidity when needed to resist displacement and flexibility when needed to accommodate slab movements.
