Resilient Cable Transit with Recessed Rim for Insect Barrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable transits do not effectively prevent insects such as wasps and spiders from accessing devices through cable openings, which can cause malfunctions and pose hazards to service personnel.
Innovation Solution
A one-piece, resilient cable transit with a recessed design and cylindrical rim portions, featuring a frame with axial extensions and through-holes, and optionally a diaphragm and slit for flexibility and structural stability, formed from materials like silicone or rubber compounds, providing an insect-proof barrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cable transit is made from resilient material with recessed design to provide flexibility and mounting convenience, then ease of operation is improved, but structural stability may deteriorate
Solution Approach 1:
The cable transit is divided into a frame portion and a body portion made of resilient material. The frame provides structural stability while the resilient body provides flexibility and mounting convenience. This segmentation allows each part to fulfill its specific function without compromise.
Solution Approach 2:
Different portions of the cable transit have different material properties - the frame is rigid for stability, while the body is resilient for flexibility. The cylindrical rim portions and recessed volumes create local variations in material distribution to balance structural integrity with mounting flexibility.
2Ease of operation
If the cable transit is designed with through-holes and cylindrical rim portions for cable passage, then ease of operation is improved, but reliability in preventing insect access deteriorates
Solution Approach 1:
The cylindrical rim portions are nested within the frame structure, creating a multi-layer barrier. The recessed volumes between the rim portions and frame create additional depth, forming a nested structure that makes it difficult for insects to reach through while still allowing cable passage.
Solution Approach 2:
The design adds a radial dimension to the barrier by creating recessed volumes between the cylindrical rim portions and the frame. This radial recess creates an additional dimensional obstacle that prevents insects from directly accessing the cable opening while maintaining cable installation capability.
3Strength
If the cable transit is made as a one-piece structure for robustness, then strength is improved, but adaptability to different mounting situations deteriorates
Solution Approach 1:
The resilient material allows the cable transit to change its physical parameters (shape, volume) in response to mounting conditions. The material can compress and deform to adapt to different opening sizes and mounting surfaces while maintaining structural integrity through its elastic properties.
Solution Approach 2:
The cable transit transitions from a static rigid structure to a dynamic resilient structure that can adapt its shape during installation. The resilient body can deform to accommodate different mounting scenarios while the one-piece construction maintains overall structural robustness.

AI summary
A cable transit (100) is formed in one piece and comprises a frame (102) and a body formed from resilient material. The frame (102) is dimensioned to be inserted into an opening of a separating wall and has an axial extension L from a first end (104) to a second end (106). At least one through-hole (108) extends through the body in the axial extension thereof, and the cable transit is characterized in that the at least one through-hole (108) is defined by a cylindrical rim portion (110) and in that a volume (114) between the cylindrical rim portion (110) of the at least one through-hole and a frame (102) of the cable transit is recessed.
