Replaceable Icon and Speaker Module for Chassis Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in efficiently managing and replacing icons and speakers within the base chassis without damaging the chassis or requiring motherboard replacement.
Innovation Solution
A modular housing system for animated touch-actuated icons and speakers that allows for removal and replacement without separating the base chassis covers, using a replaceable icon and speaker module with capacitive sense circuitry and LED arrays for dynamic icon display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If icons and speakers are integrated into the base chassis, then the system structure is simplified, but replacement of icons or speakers requires separation of base chassis covers which may cause cracking or destruction of chassis components
Solution Approach 1:
The patent divides the base chassis into functional modules: a fixed base chassis housing containing motherboard and speakers, and a removable icon module that can be independently replaced. This segmentation allows icon replacement without separating base chassis covers, resolving the contradiction between structural simplicity and ease of repair.
2Loss of information
If multiple static icons are displayed, then each icon status is clearly indicated, but space is wasted and customization is limited
Solution Approach 1:
The patent implements dynamic icons using LED arrays that can display multiple states (on/off, different colors) within a single icon location. The capacitive touch sensor enables the icon to respond to user interaction, allowing one icon to represent multiple statuses rather than requiring separate static icons for each state, thus saving space while maintaining clear status indication.
Solution Approach 2:
The patent changes the visual parameters of the icon (brightness, color, illumination state) to indicate different statuses. By varying these parameters rather than using multiple physical icons, the system conveys more information in the same space and allows user customization of icon selection and behavior.
3Area of stationary object
If a single icon is used to indicate multiple statuses, then space is saved, but the icon may be less visually distinct for each status
Solution Approach 1:
The patent uses color changes in the LED array to clearly distinguish different icon statuses. Different colors or brightness levels provide visual differentiation that maintains clear status indication while using a single icon location, resolving the contradiction between space efficiency and visual distinctiveness.

AI summary
A base chassis assembly for an information handling system allowing user replacement of touch-actuated icons and speaker comprises a base chassis top cover joined to a base chassis bottom cover to form the base chassis assembly housing a motherboard, and having an opening for receiving a replaceable icon and speaker module to be operatively coupled to the motherboard. The replaceable icon and speaker module including plural acrylic layers forming an icon panel including a touch icon zone with icons formed from etching light prism arrays in the plural acrylic layer bottom surfaces for refracting colored light from a light emitting diode (LED) side-mounted at a determined angle from each acrylic layer to illuminate the icons, and a capacitive sense circuit board for detecting user touch at the touch icon zone, and an associated user input, based upon identification of the illuminated icon.
