Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ladder safety devices are cumbersome to install and store, and they do not effectively prevent accidents such as slipping or falling from the ladder.
Innovation Solution
A safety device for ladders comprising a guard member with protruding cover portions and fixing members that can be easily mounted and stored, featuring a guard member that covers the rear surface of the ladder to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional safety devices are used on ladders, then user safety is improved, but device complexity and installation burden increase
Solution Approach 1:
The safety device is divided into separate functional components: a guard member for safety coverage and fixing members for attachment. This segmentation allows each component to be optimized independently and simplifies installation compared to monolithic conventional designs.
Solution Approach 2:
The guard member serves multiple functions: it provides safety coverage, acts as a footrest, and offers structural support. This multi-functionality reduces the need for additional separate components, simplifying the overall device configuration while maintaining safety.
2Reliability
If conventional safety devices are installed on ladders, then user safety is improved, but installation time and storage difficulty increase
Solution Approach 1:
The fixing members are pre-configured to attach to the guard member in a predetermined arrangement, allowing for quick installation without complex assembly steps. The pre-planned configuration enables rapid deployment while ensuring proper safety positioning.
Solution Approach 2:
The safety device is designed to be detachable and reconfigurable, allowing users to quickly install, remove, and reposition the device as needed. This dynamic design reduces installation time and improves storage convenience compared to permanent fixed installations.
3Reliability
If the guard member covers the rear surface of the ladder, then safety coverage is improved, but device complexity increases
Solution Approach 1:
The guard member is integrated with the fixing members into a unified assembly that works together as a single functional unit. This merging simplifies the overall device configuration while ensuring comprehensive safety coverage through the coordinated action of its components.

AI summary
A safety device for a ladder for protecting a user of the ladder is provided. The safety device includes a guard member formed extending in one direction, the guard member being mountable on the ladder, and a plurality of fixing members connected to the guard member, spaced apart from each other along a longitudinal direction of the guard member, and configured to fix the guard member to the ladder, wherein the guard member is configured to protrude at least partially toward a mar side of the ladder and cover a rear surface of the ladder.
