Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional teleprompters occupy a large space during transportation and storage due to their non-foldable light shield components.
Innovation Solution
A foldable teleprompter design featuring a main shell with a rotatable beam splitter and supporting plate that can be flipped to accommodate the light shield, allowing the beam splitter to be sealed within the main shell, along with a flexible foldable light shield and pivot connection for stable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the light shield part is designed as a traditional rigid structure, then it provides effective light shielding function, but it occupies a large space during transportation and storage
Solution Approach 1:
The light shield is transformed from a static rigid structure to a dynamic flexible structure that can change its configuration. During normal operation, it extends to provide light shielding; during transportation, it folds back along the guide groove to minimize space occupation. This dynamic adaptability resolves the contradiction between maintaining shielding function and reducing transport volume.
Solution Approach 2:
The flexible light shield is designed to nest within the main body structure during transportation. By folding back along the guide groove formed by the first and second side walls, the light shield occupies minimal space within the housing, similar to how nested dolls compactly store within each other.
2Volume of stationary object
If the beam splitter and light shield are made foldable, then space occupation is reduced during transportation, but the structural complexity increases
Solution Approach 1:
The housing is segmented into functional walls (first side wall with guide groove, second side wall forming accommodating space) that work together to enable the folding mechanism. This segmentation allows the beam splitter and light shield to be divided into movable and fixed portions, simplifying the overall folding structure while maintaining functionality.
Solution Approach 2:
The light shield is implemented as a flexible component rather than a rigid structure. This flexibility allows it to be folded back during transportation without requiring complex mechanical joints or additional fastening mechanisms, thereby reducing structural complexity while achieving compact storage.
3Reliability
If the supporting plate is designed to cover the opening when flipped, then the beam splitter is sealed and protected, but the connection structure becomes more complex
Solution Approach 1:
The supporting plate serves multiple functions simultaneously: it acts as a structural support, a sealing cover for the opening, and a protective shield for the beam splitter. By merging these functions into a single component, the design avoids the need for separate sealing elements and protective covers, thereby simplifying the overall connection structure.
Solution Approach 2:
The supporting plate is designed as a multi-functional component that performs structural support, sealing, and protection functions. This universal design reduces the total number of parts required and simplifies the connection structure while ensuring reliable sealing and protection of the beam splitter during folding and storage.
