Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video output devices, such as projectors, face challenges in freely moving and rotating without twisting wires, which can cause short circuits and other issues.
Innovation Solution
A video output device is designed with a projector module that can rotate about multiple axes, including a first axis parallel to the radiation direction, a second axis intersecting the first axis, and a third axis intersecting the first and second axes. The device includes rotating devices and a connector system to prevent wire twisting during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector module rotates about multiple axes to achieve free movement, then the adaptability and versatility of the device is improved, but the wires connecting electrical components become twisted causing short circuits
Solution Approach 1:
The patent employs a dynamic wire management system where the wire routing is designed to adapt to the rotation movements. The wire path includes flexible segments and routing channels that allow the wire to dynamically adjust its position as the projector module rotates about different axes, preventing twisting and maintaining electrical connection reliability throughout the range of motion.
Solution Approach 2:
The patent introduces an intermediary wire protection mechanism, such as a rotating connector or flexible cable assembly, that acts as a mediator between the stationary electrical components and the rotating projector module. This intermediary element absorbs the rotational stress and prevents direct wire twisting, maintaining reliable electrical connections during free movement.
2Reliability
If the projector module is fixed in a specific orientation, then the electrical connections remain stable, but the device cannot be rotated to different projection directions
Solution Approach 1:
The patent transforms the static wire routing into a dynamic system that accommodates rotation. The wire path is designed with flexible sections and routing channels that move with the projector module, allowing the electrical connections to remain stable throughout the rotation range rather than being fixed in one orientation.
Solution Approach 2:
The patent segments the wire routing into multiple sections with different degrees of flexibility. Some segments are designed to remain relatively stable while others are designed to flex and adapt during rotation, allowing the system to maintain electrical connection stability while achieving projection direction adjustment capability.

AI summary
A video output device includes a projector module configured to output a content image along a radiation direction, a first rotating device configured to rotate at least a portion of the projector module about a first axis that is parallel to the radiation direction, a second rotating device configured to rotate the projector module about a second axis intersecting the first axis, a substrate electrically connected to the second rotating device, and a connector electrically connected to the substrate through a first wire, electrically connected to the second rotating device through a second wire. While the projector module rotates about the second axis, the connector is configured to prevent the first wire and the second wire from being twisted.
