Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently reusing and recycling components of portable information handling systems, particularly those containing rare earth elements like magnets, which are difficult to access and have a high carbon footprint, and in accurately assessing the wear and tear of components like hinges and keyboards to predict remaining life and ensure compatibility with replacement parts.
Innovation Solution
Implementing a standardized speaker format with a magnet that holds the housing in a closed position and using a Hall sensor for detection, along with automated speaker type identification through coil and magnet characteristics, to facilitate reuse and recycling across different platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If speakers with magnets are installed in information handling systems, then audio functionality is provided, but the amount of rare earth elements increases and recycling becomes difficult
Solution Approach 1:
The speaker magnet is designed to serve multiple functions: generating the magnetic field necessary for audio output and simultaneously acting as a closure magnet to hold the lid to the housing. This multi-functionality reduces the need for separate rare earth element magnets, thereby decreasing the overall amount of rare earth elements in the system while maintaining audio functionality.
Solution Approach 2:
The invention combines the audio speaker magnet and the closure magnet into a single integrated component. By merging these two functions into one magnet, the system reduces the total quantity of rare earth elements required, as the same magnet serves both audio generation and mechanical closure purposes.
2Adaptability or versatility
If multiple separate housing portions are used to enable convertible configurations, then adaptability and protection are improved, but device complexity increases
Solution Approach 1:
The speaker magnet serves a dual purpose: providing audio functionality and acting as a closure mechanism to hold the lid to the housing. This multi-functionality reduces the need for additional separate closure components, thereby simplifying the overall housing structure while maintaining the convertible configuration capabilities.
3Ease of manufacture
If standardized speaker format is implemented, then ease of manufacture and recycling are improved, but manufacturing precision requirements increase
Solution Approach 1:
The standardized speaker format positions the magnet in a location that serves both audio output and closure functions. This standardization simplifies manufacturing and assembly processes across different device models, while the multi-functional design ensures that the same magnet position achieves both audio performance and mechanical closure, effectively managing precision requirements.

Function Achieved in This Case
This approach allows for efficient reuse and recycling of speakers and other components by ensuring compatibility and reducing the need for rare earth elements, while also enabling automated configuration and detection of the housing position, thereby enhancing the environmental sustainability of information handling systems.
Implementation Method 1
a magnet of the speaker is aligned in a housing main portion with ferromagnetic material in a housing lid portion to hold the housing lid portion to the housing main portion
Implementation Method 2
A sensor disposed in the housing lid portion detects the speaker magnet to leverage the speaker magnet for closed position detection

AI summary
A portable information handling system housing biases to the closed position by attracting a piece of ferromagnetic material disposed in a lid housing portion to a magnet in a speaker disposed in a main housing portion. A Hall sensor proximate the ferromagnetic material detects the speaker magnet in the closed position and communicates open or closed position detection through a flexible cable and hinge to an embedded controller in the main housing for execution of logic associated with open and closed positions, such as ACPI sleep and wake states.
