Spring-Loaded Ladder Clamp for Ground-Level Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder safety mechanisms do not adequately protect the first user who must ascend the ladder to secure it, as they require manual ascension and lack portability and versatility in attachment to various structures.
Innovation Solution
A ladder safety mechanism featuring manually operated clamps that can be secured and adjusted from the bottom, combined with a fall protection device and stabilizer, allowing for secure attachment to various structures without the need for electronic power or complex mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a motorized mounting assembly is used to secure the ladder to a structure, then the ladder can be automatically secured, but the device becomes large, complex, and costly to produce
Solution Approach 1:
The clamp is designed to automatically secure itself to the structure when placed around it, without requiring motorized actuation. The spring-loaded jaw members automatically engage with the structure's surface, allowing the ladder to be secured simply by positioning the clamp around the structure.
Solution Approach 2:
The motorized mounting assembly and its power source have been removed from the system. The invention extracts the complex motorized components and replaces them with a simple manual positioning mechanism, retaining only the essential clamping function.
2Extent of automation
If a motorized mounting assembly with power source is used to secure the ladder, then automatic securing is achieved, but the device adds significant weight reducing portability
Solution Approach 1:
The power source and motor have been completely removed from the system. The invention replaces the motorized actuation mechanism with a simple spring-loaded clamping mechanism that requires no power source, dramatically reducing the overall weight of the ladder system.
3Reliability
If prior art securing devices are used, then the ladder can be secured to a structure, but the first user must ascend the ladder to secure it, offering no protection
Solution Approach 1:
The clamp is designed to be positioned and secured around the structure from the ground level before the user ascends the ladder. The spring-loaded mechanism automatically engages when the clamp is placed around the structure, securing the ladder in advance before the user needs to climb.
4Device complexity
If a simple arcuate member and rope system is used to secure the ladder to a pole, then the device is simpler and lighter, but it is limited to very specific pole-securing applications
Solution Approach 1:
The clamp is designed with adjustable jaw members that can adapt to different structure shapes and sizes. The jaw members can be positioned at different angles and distances from each other, allowing the same clamp design to secure the ladder to various structures including poles, walls, and other vertical surfaces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced safety for the first user by securing the ladder before ascent, ensuring portability, and accommodating diverse structural attachments, while maintaining compliance with safety regulations and avoiding the need for new ladder purchases.
Implementation Method 1
The clamp comprises a body and spring-loaded jaw members

AI summary
A ladder safety mechanism comprises at least one clamp, preferably a pair of spaced apart clamps, attachable part way along a ladder, to secure the ladder to part of a structure. In some embodiments, the mechanism includes at least one manually operated actuator, such as a rope or cable, coupled to the at least one clamp to enable a user located at the bottom of the ladder to open the at least one clamp to receive the part of a structure. In some embodiments, the at least one clamp is automatically secured to the part of the structure by placing the clamp onto the structure. The at least one manually operated actuator also enables a user located at the bottom of the ladder to open the at least one clamp to release the part of the structure. The at least one clamp is oriented substantially perpendicularly to a part of the structure to which the ladder is to be attached.
