Cable Management in External Devices Using Segmented Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses face issues with electric cables that are either too short or too long when attaching external devices to main units, leading to safety hazards and aesthetic concerns due to improper cable management.
Innovation Solution
The solution involves bundling electric cables together and supporting them with a casing member, allowing them to extend through a space between the casing and external cover, using different types of wires for external and internal cables based on their requirements, and employing various holding members to secure and protect the cables from damage and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric cables are extended to connect external device and main unit, then electrical connection is achieved, but cable length cannot be optimized leading to safety hazards and aesthetic issues
Solution Approach 1:
The patent divides the cable management into two segments: internal cables inside the external device and external cables connecting to the main unit. Different cable types are used for each segment based on specific requirements, allowing optimized cable length and management for each portion independently.
Solution Approach 2:
The patent applies different cable specifications to different locations: internal cables use one type suitable for inside the external device, while external cables use another type suitable for connection to the main unit. This local differentiation resolves the contradiction by allowing each cable segment to have optimal length and properties for its specific function.
2Adaptability or versatility
If multiple electric cables are routed between external device and main unit, then electrical functions are connected, but cables may cross over each other causing safety and appearance problems
Solution Approach 1:
The patent introduces a cable guiding structure as an intermediary component that manages the routing of multiple cables. This structure prevents cables from crossing over each other by providing designated pathways, thereby eliminating safety hazards and appearance problems while maintaining full electrical connectivity.
3Ease of operation
If external device is placed separately from main unit, then operational convenience is improved, but cable management becomes problematic
Solution Approach 1:
The patent employs flexible cable management solutions that can adapt to different placement positions of the external device relative to the main unit. The cable guiding structure and differentiated cable types allow the system to maintain proper cable management regardless of the external device's position, preserving operational convenience without increasing complexity.

AI summary
An external device that is electrically connected to a main unit by a plurality of electric cables includes a first casing member storing a function unit; an external cover covering the first casing member; and a first space provided between the first casing member and the external cover. The electric cables are pulled out of the first casing member, bundled together, supported by the first casing member, and extended out of the external cover through the first space.
