Removable Insert Half for Cable Sealing Waste Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insert block systems for sealing cables, wires, or pipes in partition walls generate significant waste material due to the need for multiple blocks with different diameters or removable layers to achieve a tight fit, which is inefficient and wasteful.
Innovation Solution
A flexible insert half with a body featuring a groove and recesses, where removable elements with semi-circular passages of varying radii can be arranged to adapt to different cable, wire, or pipe diameters, allowing for a single insert half to be used across various diameters by removing elements that are too small, thus providing a reliable sealing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple insert blocks with different diameters are used to accommodate different cable sizes, then the sealing fit is improved, but the material waste and device complexity increase
Solution Approach 1:
The insert block is divided into multiple removable elements (first element, second element, third element) that can be selectively removed from the groove. Each element has a different radius, allowing the user to remove elements that are too small for the cable diameter, leaving only the appropriately sized elements to form a tight seal around the cable.
Solution Approach 2:
The insert block transitions from a static, fixed-diameter design to a dynamic, adaptable design where elements can be removed based on the cable size. This allows the same insert block to adapt to multiple cable diameters, eliminating the need for multiple different insert blocks and reducing material waste.
2Manufacturing precision
If multiple insert blocks with different diameters are used to accommodate different cable sizes, then the sealing fit is improved, but the device complexity increases
Solution Approach 1:
A single insert block design serves multiple functions by accommodating cables of different diameters through the selective removal of elements. The groove can receive different combinations of elements (first element alone, first and second elements, first, second and third elements, etc.), making the insert block universal for various cable sizes without requiring multiple specialized blocks.
Solution Approach 2:
By segmenting the insert block into removable elements, the complexity is managed within a single component rather than requiring multiple complex components. The segmented design allows flexible configuration while maintaining a simple overall structure with a single groove and standardized element interfaces.
3Adaptability or versatility
If peelable layers are arranged in the groove to adapt the passage diameter, then the adaptability is improved, but the material waste increases
Solution Approach 1:
Instead of using peelable layers that are discarded, the invention uses discrete removable elements that can be selectively taken out. Each element is a substantial component that can be removed and reused or properly disposed of, reducing waste compared to peeling away layers of material from a single block.
Solution Approach 2:
The removable elements can be discarded selectively (only the ones that don't fit) rather than discarding entire insert blocks or large portions of material. The elements that remain in the groove are recovered and continue to provide sealing function, maximizing material utilization.

AI summary
The present invention relates to an insert half (10; 70) for sealing around a cable (2), pipe or wire, said insert half comprising: a body (11; 71) with a first (12) and a second end(13), a first side (14) intended to be arranged towards a corresponding first side of a substantially identical insert half(10), and a groove (15) arranged in said first side and extending between the first and second end along an axis A, wherein a number of recesses(17; 77) extending substantially transverse to the axis A are formed in the groove along axis A; and at least one insert (20; 30; 40; 80) removably arranged within said groove, said insert is formed by at least two elements (21; 31; 44; 81) bonded to each other and arranged side by side along axis A, said insert having an outside shape corresponding to the shape of the groove and the recesses such that the insert could be arranged anywhere along the groove, wherein each element comprises a semi-circular passage with different radius co-axial to axis A. The invention furthermore relates to a sealing system comprising said insert half.
