Solution Overview
Problem
The existing polyhedron type display devices face issues with increased power consumption and weight due to multiple light source units, which also create gaps between adjacent liquid crystal panels, obstructing the image display and reducing luminance.
Innovation Solution
A polyhedron type display device design that minimizes the gap distance between liquid crystal panels by using a single light source unit and a supporting structure, including a light source housing, supporting pillar, and structure supporting pedestal, to reduce power consumption and weight while ensuring uniform light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light source units are used for each liquid crystal panel, then each panel receives sufficient light, but power consumption and weight increase
Solution Approach 1:
The patent combines multiple light source units into a single shared light source that serves multiple liquid crystal panels. The light source unit is positioned at the center of the polyhedron structure and emits light that is distributed to all surrounding panels, eliminating the need for separate light sources for each panel and thereby reducing overall power consumption.
Solution Approach 2:
The single light source unit performs a universal function by providing illumination to multiple liquid crystal panels simultaneously. This multi-functional approach allows one light source to serve the entire polyhedron display structure, reducing the total number of light sources needed while maintaining adequate illumination for all panels.
2Illumination intensity
If multiple light source units are used for each liquid crystal panel, then each panel receives sufficient light, but the weight of the display device increases
Solution Approach 1:
The patent merges multiple separate light source units into a single centralized light source unit that is shared by all liquid crystal panels. This consolidation significantly reduces the total weight of the display device by eliminating redundant light source components while maintaining adequate illumination for all panels through strategic positioning and light distribution.
3Illumination intensity
If light source units are disposed for each liquid crystal panel, then each panel has independent light supply, but gap distance between panels increases obstructing image display
Solution Approach 1:
The patent merges the light source functions into a single centralized unit positioned at the polyhedron center, which eliminates the need for individual light source units attached to each panel. This allows the liquid crystal panels to be positioned closer together with minimal gap distance, as the shared light source illuminates all panels without requiring physical attachment or proximity of separate light sources to each panel.
4Use of energy by moving object
If the number of light sources is decreased to reduce power consumption, then power consumption is reduced, but luminance is reduced and light sources become visible
Solution Approach 1:
The patent transitions from a two-dimensional arrangement where light sources are attached to or near each panel surface to a three-dimensional configuration where a single light source is positioned at the center of the polyhedron structure. This spatial repositioning allows the light to radiate uniformly in multiple directions, providing adequate luminance to all panels without requiring multiple light sources, thus maintaining brightness while reducing power consumption.
Solution Approach 2:
The patent applies local quality by positioning the single light source at the geometric center of the polyhedron structure, where it can optimally illuminate all surrounding panels. This strategic positioning ensures that light is distributed evenly to all panels, maintaining uniform luminance across the display while using only one light source, thereby avoiding the need for multiple light sources that would increase power consumption.
