Temporary Anchoring Device for Fall Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring devices for personal protective equipment (PPE) at height are cumbersome, time-consuming to install, damage structures, and are not suitable for short-duration interventions, leading to safety risks for workers due to their complexity and requirement for wall modifications, making them impractical for frequent use.
Innovation Solution
A portable, temporary anchoring device with a single upright structure that adjusts to fit between a floor and ceiling, equipped with telescopic bars and fine adjustment mechanisms, allowing quick setup and secure attachment of PPE without damaging the structure, and featuring a cable system to prevent arm separation and an anchor ring positioned to minimize fall force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If structural anchors or mobile anchors requiring wall drilling are used, then anchoring strength is improved, but installation time increases and structural damage occurs
Solution Approach 1:
The device divides the anchoring system into separate functional components: a ceiling-mounted anchoring unit and a floor-based support structure. This segmentation eliminates the need for wall drilling while distributing loads across multiple contact points, resolving the contradiction between anchoring strength and installation time by providing immediate installation without structural modification.
Solution Approach 2:
The patent introduces an intermediary floor support structure that works in conjunction with the ceiling anchoring point. This intermediary element provides additional stability and load distribution without requiring wall penetrations, thereby achieving strong anchoring效果 with rapid installation by combining ceiling and floor support mechanisms.
2Strength
If structural anchors requiring chemical sealing are used, then anchoring strength is improved, but installation time increases due to waiting time
Solution Approach 1:
The device uses mechanical expansion and friction-based anchoring mechanisms that are activated immediately upon installation, eliminating the need for chemical sealing and associated waiting periods. The anchoring strength is achieved through preliminary mechanical action rather than chemical bonding, allowing immediate use after installation.
3Ease of operation
If door or window bars are used for anchoring, then installation simplicity is improved, but safety is worsened due to lower mooring position multiplying fall force
Solution Approach 1:
Instead of placing the anchoring point at door or window level, the patent inverts the approach by positioning the primary anchoring point at the ceiling directly above the work area. This inversion places the mooring point at the most advantageous position for minimizing fall distance and force, while the floor support provides additional stability, thereby improving safety without compromising installation simplicity.
4Reliability
If scaffolding or external structures are used, then safety is improved, but device complexity and installation cost increase
Solution Approach 1:
The device combines multiple functions into a single integrated system: ceiling anchoring, floor support, and adjustable positioning. This multi-functional design eliminates the need for separate scaffolding structures while providing equivalent or superior safety, thereby reducing device complexity and installation cost while maintaining high reliability.
