Solution Overview
Problem
The existing cable configurations for communication devices often result in inefficient use of space and inadequate heat dissipation due to loose arrangements, which can impede the dissipation of heat generated by other parts in communication products, while also failing to effectively manage electromagnetic interference and power distribution.
Innovation Solution
A signal transmission cable design that integrates a communication line and a power line, wrapped together with inner and outer jackets, including a metallic jacket for grounding and reducing electromagnetic interference, and a plug with pins for secure electrical connections, allowing for simultaneous transmission of power and communication signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cables are arranged loosely in communication products, then installation and routing are simplified, but space is wasted and heat dissipation is impeded
Solution Approach 1:
The patent combines multiple cables (power cable and communication cable) into a single integrated cable assembly. The power conductors and communication conductors are bundled together with a common outer jacket, reducing the number of separate cable routes needed and improving space utilization while maintaining ease of installation through a unified structure.
2Adaptability or versatility
If multiple separate cables are used for power and communication, then functional requirements are met, but space is wasted and heat dissipation is impeded
Solution Approach 1:
The patent integrates power transmission and communication functions into a single cable assembly. Multiple conductors for different functions are bundled together with appropriate insulation and a common outer jacket, maintaining full functional capability while significantly reducing space requirements compared to separate cable arrangements.
3Volume of moving object
If cables are arranged tightly to save space, then space utilization is improved, but heat dissipation may be impeded
Solution Approach 1:
The cable assembly employs segmentation at multiple levels: individual conductors are separated by insulation layers, power conductors and communication conductors are grouped separately within the outer jacket, and the overall bundle is organized with spacing considerations. This segmented structure allows for controlled heat dissipation while maintaining compact dimensions for space-efficient installation.
4Ease of manufacture
If traditional cable configurations are used, then manufacturing simplicity is maintained, but electromagnetic interference is not effectively managed
Solution Approach 1:
The patent applies shielding techniques where a metallic shield (such as aluminum foil or mesh) is incorporated around the communication conductors within the cable assembly. This converts the potentially harmful electromagnetic interference into a controlled environment where the shield captures and redirects interference away from sensitive communication signals, while the overall manufacturing process remains relatively simple and scalable.

Function Achieved in This Case
This integrated cable design saves space by transmitting both power and communication signals efficiently, reduces electromagnetic interference through grounding and twisted pairs, and prevents damage from excessive current by distributing power through multiple paths.
