Solution Overview
Problem
Information handling systems face challenges in maintaining proper alignment of light guide plates with LEDs during pivot positions, leading to hot spots due to gravitational forces and varying environmental conditions, which affect light distribution and display quality.
Innovation Solution
Incorporating a damper with a compression portion and catch portion, featuring multiple grooves, that deforms to securely hold the light guide plate in alignment with LEDs, ensuring consistent light distribution across different orientations and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the light guide plate is rigidly fixed to maintain alignment, then alignment precision is improved, but the device cannot adapt to gravitational forces during pivot positions and varying environmental conditions
Solution Approach 1:
The patent applies the dynamics principle by implementing a damper mechanism that allows the light guide plate to dynamically adjust its position in response to gravitational forces during pivot operations and environmental variations. The damper transitions from a rigid constraint to a controlled compliance system, enabling the light guide plate to maintain proper alignment through adaptive movement rather than fixed positioning.
Solution Approach 2:
The patent employs parameter changes by utilizing the damper's compression portion to modify the physical state and position of the light guide plate based on environmental conditions. The damper compresses or extends in response to temperature changes, humidity variations, and gravitational forces, thereby adjusting alignment parameters dynamically to maintain optimal light distribution across different operating conditions.
2Adaptability or versatility
If the light guide plate is allowed to move freely to adapt to environmental conditions, then adaptability is improved, but alignment precision deteriorates leading to hot spots
Solution Approach 1:
The patent applies the intermediary principle by introducing a damper as a mediating element between the light guide plate and the display housing. This damper acts as a controlled intermediary that permits necessary movement for environmental adaptation while simultaneously maintaining alignment precision through its damping characteristics, thus preventing hot spots by regulating the light guide plate's position rather than allowing uncontrolled movement.
3Device complexity
If a simple mounting structure is used for the light guide plate, then device complexity is reduced, but reliability deteriorates under varying environmental conditions
Solution Approach 1:
The patent applies segmentation by dividing the mounting structure into distinct functional components: a damper assembly with compression and extension portions, a light guide plate, and mounting features. This segmentation allows each component to perform its specific function - the damper handles environmental adaptation while the light guide plate maintains light distribution - thereby improving reliability without requiring an overly complex integrated structure.

AI summary
A display for an information handling system includes a light guide plate, a bottom cover, and a damper. The damper in physical communication with the light guide plate and with the bottom cover. The damper includes a compression portion and a catch portion. The compression portion deforms in response to a force exerted on the compression portion by the light guide plate. The catch portion includes a first groove that interfaces with an end of the compression portion during a first environmental condition. The first groove holds the end of the compression portion and supports the light guide plate when the display is in a pivot position during the first environmental condition.
