Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical microcable drivers are bulky and difficult to maneuver in tight spaces, particularly in building installations, due to their size and weight, and face sealing issues when cascaded, making them unsuitable for small cable ducts and challenging to use in buildings.
Innovation Solution
A compact optical cable laying device with a rotary motor, friction drive rollers, and a compressed air inlet, where the motor, air inlet, and cable axis are parallel, facilitating easy manipulation and sealing, featuring a pivoting air inlet and adjustable clamping system to accommodate cables of varying diameters and stiffness, and a lightweight design with interchangeable battery power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional air injection system with drive rollers is used, then cable laying function is achieved, but device becomes bulky and difficult to maneuver in building spaces
Solution Approach 1:
The device is divided into separate functional modules: a motor unit with drive rollers and a separate air injection unit. This segmentation allows the components to be arranged in a compact, linear configuration along the cable axis, reducing the overall device volume while maintaining all necessary functions for cable laying.
Solution Approach 2:
The motor axis, compressed air inlet direction, and cable drive direction are all aligned substantially parallel to one another, creating a linear one-dimensional arrangement. This dimensional alignment minimizes the device footprint in perpendicular directions, making it suitable for maneuvering in tight building spaces and cable ducts.
2Adaptability or versatility
If air injection system is placed upstream of drive rollers, then cable laying is achieved, but sealing problems occur when cascading devices
Solution Approach 1:
Instead of placing the air injection system upstream of the drive rollers as in traditional designs, this invention positions the motor and drive rollers upstream, with the air injection system positioned downstream or adjacent to them. This inverted arrangement allows the airtight volume to be properly sealed when devices are cascaded, preventing air leaks while maintaining cable laying functionality.
3Volume of moving object
If device size is reduced for building use, then maneuverability improves, but cable laying performance may be compromised
Solution Approach 1:
The motor unit and air injection unit are merged into a single integrated device with all components arranged along a common axis. This combination allows the device to maintain full cable laying functionality while achieving a compact size suitable for building installations, as the merged design eliminates redundant structures and optimizes space utilization.
