Adjustable Cord Hanger for Damage-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hangers for mounting objects on surfaces are difficult to assemble, limit the range of object sizes and shapes they can accommodate, and may exert damaging pressure on objects due to the use of springs or bungee cords.
Innovation Solution
A hanger design featuring a frame with adjustable cord links, allowing for secure mounting on various surfaces without damaging pressure, using a cord fastener for lockable adjustment and hooks for gripping objects, and made from durable materials like stainless steel wire and nylon cord.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If springs or bungee cords are used to provide adjustment for mounting objects, then the hanger can accommodate a fixed diameter range of plate sizes, but the assembly becomes difficult and may cause pinched fingers or broken plates
Solution Approach 1:
The patent removes the springs or bungee cords from the mounting mechanism and replaces them with a simple cord system that threads through apertures in the frame parts. This extraction eliminates the dangerous retracting force while maintaining the adjustment capability through the cord's flexibility and the fastener's adjustability.
Solution Approach 2:
The patent uses a simple, replaceable cord instead of durable springs or bungee cords. The cord can be easily replaced if needed and does not pose the same safety risks. The cord fastener provides a simple, inexpensive mechanism for adjustment without the complexity and danger of spring mechanisms.
2Adaptability or versatility
If springs or bungee cords are extended to or near their limits, then they can accommodate larger objects, but significant pressure may be exerted causing damage to the object being hung
Solution Approach 1:
By removing the springs and bungee cords that generate excessive pressure when extended, the patent eliminates the source of damage to mounted objects. The cord system maintains tension without the elastic rebound force that causes harmful pressure.
Solution Approach 2:
The patent changes the mechanical parameters of the tensioning system by using a inelastic cord instead of elastic springs. This allows for accommodation of larger objects through increased cord length rather than through increased tension force, thereby maintaining low pressure on mounted objects while expanding the size range.
3Reliability
If a cord fastener with clamping roller is used for lockable adjustment, then the cord length can be securely fixed, but the device complexity increases
Solution Approach 1:
The fastening mechanism is divided into simple functional components: a housing with a wider end and a narrower end, and a clamping roller that moves longitudinally within the housing. This segmentation allows for reliable adjustment while keeping each component simple and easy to manufacture.

AI summary
The invention relates to a hanger for mounting objects of various shapes and sizes on vertical, sloping or horizontal surfaces. The hanger comprises a frame formed by two opposing parts adapted to grip the object, and linked together by an adjustable length of cord so that the frame can be made to fit precisely the object to be hung. The disadvantages of the prior art hangers that rely on springs to provide for the adjustment needed for them to fit a range of sizes will be overcome.
