Engineering Contradiction Analysis
1Ease of manufacture
If only an elastic sealing element is used for sealing, then the installation is simple, but rainwater runoff is undefined leading to water stains on the wall surface
Solution Approach 1:
The sealing function is separated from the water runoff control function. The elastic sealing element (sealing ring) is placed on the third intermediate piece to seal against the outer wall surface, while a separate drip edge structure is integrated into the third intermediate piece to define and control water runoff. This segmentation allows both simple sealing and effective water management.
Solution Approach 2:
The third intermediate piece acts as an intermediary element between the sealed bore passage and the external environment. It provides both the sealing interface with the wall and the drip edge structure that redirects water away from the wall surface, preventing water stains while maintaining a simple sealing mechanism.
2Ease of operation
If the intermediate disks are fixed perpendicular to the wall surface, then the installation is straightforward, but they cannot align with angled bores
Solution Approach 1:
The intermediate pieces are designed with dynamic adjustment capabilities. The first intermediate piece can be rotated or angled to align with the bore axis when the bore is not perpendicular to the wall surface. The tension elements provide adjustable clamping force to secure the pieces in their optimal positions. This dynamic design allows straightforward installation while adapting to both perpendicular and angled bores.
3Adaptability or versatility
If tension elements are used to clamp the intermediate disks, then the device can accommodate various wall thicknesses, but the installation complexity increases
Solution Approach 1:
The clamping function is distributed across multiple tension elements (first, second, and third tension elements) that are integrated with the respective intermediate pieces. Each tension element independently adjusts the clamping force for its associated intermediate piece, allowing accommodation of various wall thicknesses while maintaining a systematic rather than chaotic complexity. The segmented approach makes the installation process more manageable.
4Ease of operation
If the wall penetration creates a direct path through the wall, then cable routing is simple, but thermal insulation and soundproofing are compromised
Solution Approach 1:
The intermediate pieces are nested within the bore passage, with each piece fitting inside the wall structure. The first intermediate piece is positioned in the inner bore section, the second in the middle section, and the third in the outer bore section. This nesting creates multiple interfaces and potential insulation zones that reduce thermal bridging and sound transmission, while still allowing simple cable routing through the central passage.
Solution Approach 2:
The intermediate pieces act as intermediary structures between the interior and exterior of the wall. They interrupt the direct thermal and acoustic pathways created by a simple bore hole, providing multiple sealing surfaces and potential insulation zones. The tension elements and sealing rings further enhance this mediating function by creating tight interfaces that reduce energy loss and sound transmission.

AI summary
The invention relates to a wall penetration for passing cables through a bore in a wall. The object of the invention is, in particular, to provide a wall penetration for a round bore in which the bore axis is either perpendicular to the wall surface or is inclined at an angle in any direction relative to the wall surface. This object is achieved by connecting an inner intermediate disk and an inner inner sleeve 7 of the wall penetration via joints 10 with mutually aligned joint axes 11, and/or by connecting an outer intermediate disk 9b and an outer inner sleeve 27 of the wall penetration via joints 10 with mutually aligned joint axes 11.
