Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing covers for trenches in cable management systems require significant manual effort to open, necessitating heavy equipment and labor due to their design, which complicates access to the cable management system.
Innovation Solution
A cover for trenches in cable management systems featuring a spring-assisted hinge that allows the cover to be opened easily, with a force requirement of less than 25 lbs, and can be opened 180° to lay flat, providing full coverage and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cover is designed to fully cover the trench for complete protection, then cable protection and operational safety are improved, but the force required to open the cover increases significantly
Solution Approach 1:
A spring mechanism is integrated into the hinge assembly to provide counterbalancing force against the weight of the cover plate. The spring is positioned and tensioned to offset a portion of the gravitational force, reducing the manual effort needed to lift and open the cover while maintaining full coverage for cable protection.
Solution Approach 2:
The spring-assisted hinge acts as an intermediary mechanism between the cover plate and the trench frame. It mediates the interaction by providing mechanical assistance through spring force, enabling easy opening while the cover remains substantial enough to provide complete protection when closed.
2Reliability
If a cover is designed to be manually opened, then full coverage and protection are achieved, but labor effort and additional equipment like forklifts are required
Solution Approach 1:
The spring-assisted hinge enables the cover to open with minimal human intervention. The spring mechanism automatically provides the necessary lifting force, allowing a single operator to easily open the cover without requiring external equipment or multiple workers, thus making the system self-servicing.
Solution Approach 2:
The spring counterbalances the cover weight, transforming a heavy manual lifting operation into a light operational task. This reduces labor effort from requiring forklifts or multiple workers to simply activating the spring-assisted opening mechanism.
3Ease of operation
If a spring-assisted hinge is added to reduce opening force, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The spring-assisted hinge serves as a compact intermediary component that mediates between the cover weight and the operator's effort. While it adds a mechanical element, the design integrates the spring within the hinge structure itself, minimizing space requirements and maintaining relative simplicity compared to alternative heavy-lifting solutions.
Solution Approach 2:
The spring mechanism changes the force parameter required to open the cover by storing and releasing elastic potential energy. This parameter change enables easy operation with minimal force input, while the hinge assembly itself remains a relatively simple mechanical structure that can be manufactured and maintained with standard techniques.
