Remote-Actuated Hanger Clip Cam Mechanism for Ladder-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for hanging Christmas lights or similar ornaments on building surfaces, such as gutters and shingles, often require the use of ladders, posing safety risks and increasing the time and effort required for the task.
Innovation Solution
A hanger clip system comprising a housing with a cam member that rotates to change the position of a follower, allowing the clip member to move between open and closed configurations, which can be remotely actuated using a pole, eliminating the need for ladders by securely attaching to surfaces or protrusions without manual ladder use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ladder is used to attach ornaments to building surfaces, then the attachment can be achieved, but safety risks increase and time consumption increases
Solution Approach 1:
The patent introduces a pole as an intermediary tool that transmits force from the ground level to the hanger clip on the building surface. The pole enables remote actuation of the cam mechanism, allowing the user to operate the clip from a safe distance without needing to climb a ladder, thus eliminating safety risks while reducing time consumption
2Ease of operation
If a manual clip is used to attach ornaments, then the attachment is simple, but it requires manual access to elevated locations
Solution Approach 1:
The patent employs a dynamic cam mechanism that transforms rotational motion into linear motion to open and close the clip. This dynamic system allows the clip to be easily opened and closed through simple rotational movement of the cam, which can be remotely actuated via a pole, making the attachment process simple while enabling access to elevated locations without manual climbing
3Reliability
If a permanently attached clamping mechanism is used, then the attachment is secure, but the device complexity and installation requirements increase
Solution Approach 1:
The patent divides the attachment system into separate components: a hanger clip with cam mechanism that can be independently installed and removed, and a pole for actuation. This segmentation allows the clip to be securely attached using the cam-follower mechanism while simplifying installation and removal, as the clip can be independently positioned and secured without complex permanent installation requirements
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 hanger clip system allows for safe and efficient attachment of ornaments from the ground level, reducing safety risks and time, and can be used on various surfaces and protrusions, including gutters, shingles, and other architectural features.
Implementation Method 1
the housing and clip member are configured to receive a cam member which is configured to rotate within the housing to change the position of the follower to move the clip member between an open configuration and a closed configuration
Implementation Method 2
The hanger clip may comprise a biasing means configured to bias the clip member in a closed configuration. The biasing means may comprise a spring.
Implementation Method 3
The clip member may be pivotably connected to the housing. The pivot may comprise a joint and/or a resilient portion which allows the clip member to rotate with respect to the housing.
Data Source
AI summary
A hanger clip is disclosed comprising: a housing and a clip member for attaching the hanger to a surface or protrusion. The clip member is connected to the housing and comprises a follower, wherein the clip member is configured to move between an open configuration and a closed configuration based on the position of the follower. The housing and clip are configured to receive a cam member which is configured to rotate within the housing to change the position of the follower to move the clip member between an open configuration and a closed configuration. The hanger clip can therefore be remotely actuatable using a tool attached to a pole which can be manipulated from ground level.
