Solution Overview
Problem
Miniaturized projection devices face challenges in optimizing space utilization due to the need for proper configuration of components in limited interior spaces, leading to poor space efficiency and increased volume.
Innovation Solution
The use of a frame with distinct assembling portions for the optical engine assembly and electronic components allows for different assembling directions, preventing excessive component stacking and enabling efficient space utilization, while integrating the optical engine assembly and frame simplifies manufacturing and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If components are stacked in a single direction to fit limited interior space, then all components can be accommodated, but space utilization becomes poor and device volume increases
Solution Approach 1:
The patent applies multi-directional stacking by arranging components in both first and second directions that are not parallel to each other. The first component is stacked in a first direction while the second component is stacked in a second direction, transforming the single-dimension stacking approach into a multi-dimensional arrangement. This enables better space utilization within the limited interior space without increasing device volume, directly resolving the technical contradiction between accommodating all components and minimizing device volume.
2Volume of moving object
If components are arranged in limited interior space, then device miniaturization is achieved, but space efficiency deteriorates
Solution Approach 1:
The patent utilizes non-parallel stacking directions (first direction and second direction) to arrange components in three-dimensional space rather than stacking them linearly. This multi-directional arrangement maximizes the utilization of available interior space by distributing components across multiple spatial dimensions, thereby improving space efficiency while maintaining miniaturized device volume.
Solution Approach 2:
The patent implements nested arrangement where components are stacked in overlapping or interlocking configurations across different directions. The first component and second component are positioned such that they utilize overlapping spatial regions efficiently, allowing maximum component density within the constrained interior space without compromising space efficiency.
3Adaptability or versatility
If multiple components are configured in limited space, then device functionality is complete, but configuration complexity increases
Solution Approach 1:
The patent divides the component arrangement into distinct stacking directions (first direction and second direction), creating modular configuration zones. This segmentation of the spatial arrangement simplifies the overall configuration complexity by organizing multiple components into structured directional groups, making the complex multi-component system more manageable while maintaining complete device functionality.
