Solution Overview
Problem
Existing bath curtain rod installation methods require drilling into walls or using adhesives, which can be invasive and damaging, and lack flexibility in installation options.
Innovation Solution
The development of adjustable bath curtain rod assemblies that utilize frictional engagement and threaded fasteners for secure installation without damaging the walls, featuring telescoping tubes and extendable contact ends with pads for frictional engagement, allowing for easy installation and repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If drilling into walls and using screws to secure the rods, then the installation strength is improved, but the wall damage and installation complexity increase
Solution Approach 1:
The patent introduces wall anchors as intermediary elements that are inserted into pre-drilled holes and expanded to provide secure mounting points. These anchors act as mediators between the screws and the wall surface, distributing the load and reducing direct damage to the wall structure while maintaining strong attachment.
Solution Approach 2:
The patent employs adjustable bath curtain rod assemblies where the tube length and positioning can be modified. This allows the rods to be adapted to different wall distances and configurations, enabling secure installation without requiring extensive drilling or modification of the wall structure.
2Object-affected harmful factors
If using adhesives to secure the rods, then the wall damage is reduced, but the installation strength and reliability decrease
Solution Approach 1:
The patent divides the mounting system into separate functional components: wall anchors for structural attachment and adhesive elements for supplementary bonding. This segmentation allows each component to perform its specialized function - anchors provide mechanical strength while adhesives fill gaps and prevent loosening, achieving both low wall damage and high installation strength.
3Ease of manufacture
If using fixed-length rods, then the manufacturing simplicity is improved, but the adaptability to different wall distances decreases
Solution Approach 1:
The patent implements telescoping tube assemblies where inner tubes can slide within outer tubes, allowing the effective length to be dynamically adjusted based on the distance between walls. This dynamic structure maintains manufacturing simplicity by using standard tube components while providing versatility in installation configurations.
4Adaptability or versatility
If using telescoping tubes with mechanical fasteners, then the adaptability to different positions is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the fastening function into separate mechanical fastener components that can be independently applied to the telescoping tubes. This allows the tube adjustment mechanism to remain relatively simple while adding fastening capability through separate, easily attached components rather than integrating complexity into the tube structure itself.
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 a secure, non-invasive installation method that allows for easy adjustment and removal of bath curtain rods, offering flexibility in installation options and withstanding significant loads without the need for drilling or adhesives.
Implementation Method 1
securing the bath curtain rod assembly on the bath support structure by frictional engagement between the pad and the bath support structure
Implementation Method 2
at least one mechanical fastener threadingly engaged with the threaded hole of the first tube and engageable with an outer surface of the second tube to thereby lock the second tube into the axial position with respect to the first tube
Data Source
AI summary
Bath curtain rod assemblies are disclosed comprising axially movable tubes that may be locked into position in relation with each other. A contact end is extended from one of the tubes to engage and press against a bath support structure to firmly secure the assembly in place. The contact end includes at least one hole for receiving a mechanical fastener such as a screw, which allows the installer to choose whether or not to use mechanical fasteners when installing the rod assembly. The bath curtain rod assemblies may be installed quickly and easily in bath and shower stalls without the necessity of mechanical fasteners or adhesives, while allowing the installer to use mechanical fasteners if desired.
