Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser projection screens face challenges in accurate alignment and joining of side frames, leading to misplacement and uneven seams due to inaccurate positioning, which complicates assembly and reduces mounting efficiency.
Innovation Solution
A screen frame design featuring side frames connected by at least two connectors, including a first connector with a fastener direction perpendicular to the plane and a second connector with a fastener direction parallel to the plane, utilizing telescopic engaging members for precise positioning and easy assembly, allowing for quick and accurate alignment and fixing of side frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If side frames are connected by traditional single-direction connectors, then assembly is simpler, but positioning accuracy deteriorates leading to misplacement and uneven seams
Solution Approach 1:
The patent transitions from single-direction connector alignment to multi-directional positioning by introducing connectors with fasteners that insert from both perpendicular and parallel directions relative to the screen frame plane. This dimensional approach enables accurate positioning of adjacent side frames by constraining movement in multiple axes simultaneously, thereby improving positioning accuracy without excessive complexity
Solution Approach 2:
The connector serves as an intermediary component that mediates the connection between adjacent side frames. By incorporating multiple fasteners with different inserting directions, the connector acts as a multi-functional mediator that simultaneously achieves positioning, alignment, and mechanical connection, resolving the positioning accuracy issue while maintaining reasonable structural complexity
2Manufacturing precision
If multiple connectors with different fastener directions are used, then positioning accuracy improves, but assembly complexity increases
Solution Approach 1:
The connector structure is designed with pre-positioned fasteners at specific locations and orientations. The first fastener is pre-configured to insert from a direction perpendicular to the screen frame plane, while the second fastener is pre-configured to insert from a direction parallel to the plane. This preliminary arrangement of fasteners enables accurate positioning to be achieved automatically during assembly, improving alignment accuracy while maintaining ease of operation
Solution Approach 2:
The connector is designed as a multi-functional component that simultaneously performs positioning, alignment, and mechanical connection functions. By integrating multiple fasteners with different inserting directions into a single connector structure, the design achieves accurate positioning of side frames while maintaining simple assembly operations, as all positioning functions are consolidated into one universal connector component
