Cable Organizing Assembly for Liquid Ingress Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In robust computers, liquids entering from the side with the keyboard can easily flow along cables and damage the circuit board, as there is no effective barrier to prevent liquid ingress.
Innovation Solution
A cable organizing assembly with a cable fastening member and limiting cover is integrated into the electronic device, featuring non-parallel cable grooves and a penetration hole, which directs cables to bend and seal notches, using waterproof adhesives and engagement slots to block liquid entry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cables are directly connected from the keyboard side to the circuit board, then cable connection is simple, but liquid can easily enter along the cable and damage the circuit board
Solution Approach 1:
A cable organizing assembly is introduced as an intermediary component between the cable and the circuit board. This assembly includes a body with a cavity that receives the cable, and a waterproof adhesive layer that seals around the cable. The intermediary structure prevents liquid from traveling along the cable to the circuit board while maintaining the cable connection
Solution Approach 2:
The cable path is segmented into distinct zones: the cable enters the cable organizing assembly through a first opening, is received within the cavity, and exits through a second opening. This segmentation creates discrete sealing points where waterproof adhesive can be applied, effectively blocking liquid ingress paths without complicating the overall cable routing
2Object-affected harmful factors
If a cable organizing assembly with sealing structure is added, then liquid ingress is prevented, but device complexity increases
Solution Approach 1:
The cable organizing assembly merges multiple functions into a single component: cable routing guidance, cable positioning, and liquid sealing. The body structure simultaneously provides the cavity for cable reception and the mounting features for attachment to the device housing, eliminating the need for separate sealing components and reducing overall complexity
Solution Approach 2:
The cable organizing assembly serves multiple purposes: it organizes and secures the cable within the device, provides a sealed barrier against liquid ingress, and acts as a mounting structure for attachment to the housing. This multi-functionality reduces the number of separate components needed, thereby reducing overall device complexity

AI summary
The present invention discloses an electronic device and a cable organizing assembly. The electronic device includes a main structure with a body and the cable organizing assembly. The body has a penetration hole passing through the body and extends from a bottom surface to form a wall having a notch. The cable organizing assembly includes a cable fastening member fixed at the wall and correspondingly sealing the notch. The cable fastening member includes multiple cable grooves for fastening at least one cable. The central axis of each cable groove is not parallel to the central axis of the penetration hole. Cables pass through the penetration hole from one side of a top surface, become bent, and are fixed on one side of the bottom surface of the body by the cable organizing assembly. Thus, a liquid from the exterior is unlikely to enter along the cables into the interior.
