Display Cable Backplane for Hinge-Up Camera Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in tracking the remaining life of components, predicting failures, and efficiently reusing hinge up cables that communicate between the motherboard and display, which are prone to wear and tear, leading to unpredictable signal loss and increased environmental impact.
Innovation Solution
A snap-in cable retainer system that securely couples a cable backplane to the information handling system housing, with edge card connectors aligned to the motherboard, and monitors communication link performance through tracking link training events and power use to predict failures and guide component reuse or recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cables are included to communicate between the motherboard and display, input/output boards, and power, then communication reliability is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent combines multiple separate communication functions (display data, camera data, power) into a single integrated cable backplane assembly. This backplane contains multiple conductors that simultaneously carry different signal types, reducing the total number of cables while maintaining all necessary communication channels between the motherboard and lid components.
Solution Approach 2:
The cable backplane serves multiple functions simultaneously: it provides power delivery, high-speed data transmission for display, and communication channels for camera and other sensors. This multi-functional design eliminates the need for separate dedicated cables for each function, simplifying the overall system architecture.
2Reliability
If robust cable solutions are used to prevent hinge-up cable failure, then reliability is improved, but device complexity and cost increase
Solution Approach 1:
The cable backplane is designed as a modular assembly that can be independently replaced without affecting other system components. This segmentation allows for easier maintenance and reduces the complexity of implementing robust failure prevention, as the entire backplane unit can be swapped out if needed rather than reinforcing individual cable sections.
Solution Approach 2:
The cable backplane acts as an intermediary component between the motherboard and lid components, centralizing the connection management. This mediator approach simplifies the mechanical interface and reduces the complexity of cable routing through the hinge mechanism, as the backplane provides a structured, organized connection path.
3Object-affected harmful factors
If components are harvested and reused from failed information handling systems, then environmental impact is reduced, but tracking remaining life and predicting failures becomes more difficult
Solution Approach 1:
The system incorporates monitoring that tracks the operational status and performance metrics of the cable backplane and connected components. This feedback mechanism collects data on usage patterns, signal integrity, and potential degradation, enabling better prediction of component remaining life and more informed decisions about reuse versus recycling.

AI summary
An information handling system includes a camera communication link within a display substrate to communicate between a camera in a lid housing portion and a motherboard in a main housing portion through the display substrate. Spring biased connectors of the camera bias against contact pads formed in the display substrate to send the camera visual images through the communication link in the display substrate and then a display cable to the motherboard.
