Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face challenges in efficiently processing and storing information due to variations in technology and user needs, leading to issues such as vibration-induced degradation of hard disk drives and competition for space between visual indicators and vibration isolators.
Innovation Solution
The integration of an information indication assembly within the information handling system, which includes a light emitter, multiple conductors, a pin made of rigid material, and a grommet made of elastic material, allows for both vibration isolation and visual indication, such as status lights, without consuming additional space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate vibration isolators and visual indicators are installed in the information handling system, then both vibration isolation and status indication functions are achieved, but the system footprint increases and space is consumed
Solution Approach 1:
The patent combines the vibration isolation function and visual status indication function into a single integrated assembly. The grommet houses both the elastic material for vibration isolation and the light emitter for visual indication, allowing both functions to be achieved within the same spatial footprint rather than requiring separate components.
Solution Approach 2:
The information indication assembly serves multiple functions simultaneously: it provides vibration isolation through the elastic material in the grommet, visual status indication through the light emitter, and structural support through the pin. This multi-functional design eliminates the need for separate dedicated components for each function.
2Stability of the object's composition
If traditional rigid fastening methods are used to secure the information indication assembly, then structural stability is achieved, but vibration transmission to components increases
Solution Approach 1:
The grommet is constructed from composite materials including an elastic material that provides vibration isolation properties. This elastic material absorbs and dampens vibrations while the overall assembly maintains structural stability through the combination of rigid pin and flexible grommet components.
Solution Approach 2:
The elastic material within the grommet acts as an intermediary element between the rigid pin and the mounted component. It provides a compliant interface that isolates vibrations while maintaining the structural connection, preventing direct transmission of vibrations to sensitive components.

AI summary
In one or more embodiments, an information handling system may include an information indication assembly. For example, the information indication assembly may include at least one light emitter; multiple conductors coupled to the at least one light emitter; a pin that includes a rigid material and that permits the first plurality of conductors to pass through; and a grommet that includes an elastic material and configured to house the pin. In one instance, the pin and the grommet may be aligned along a longitudinal axis of the information indication assembly. In a second instance the pin and the grommet form a fastener of a fan associated with the information handling system. In another instance, the elastic material may mitigate vibrations from the fan. In one or more embodiments, a printed circuit board may include the multiple conductors. For example, the printed circuit board may be a flexible printed circuit board.
