Window Covering Leveler for Irregular Casings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window covering installation methods require precise measurements, tools, and can damage the window casing, leaving unsightly holes and being time-consuming, especially for irregularly shaped windows, and may not provide a secure fit for long or heavy coverings due to insufficient spring force.
Innovation Solution
A leveler system with a bracket and guillotine member that allows vertical adjustment of the window covering by rotating a threaded member, enabling the window covering to be leveled and securely attached to the window casing using an expandable endcap assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mounting brackets are screwed into the window casing, then the window covering is securely installed, but the window casing is damaged with unsightly holes and the installation is time-consuming
Solution Approach 1:
The patent removes the screws and drilling process from the installation system by using spring-loaded mounting brackets that expand to grip the window casing internally, eliminating holes and damage to the window casing while maintaining secure installation
Solution Approach 2:
The spring-loaded mounting bracket acts as an intermediary between the window covering and the window casing, providing a secure connection through expansion and compression forces without requiring direct screw penetration into the casing
2Reliability
If mounting brackets are screwed into the window casing, then the window covering is securely installed, but the installation process is time-consuming
Solution Approach 1:
The mounting brackets are pre-assembled with the window covering headrail before installation, allowing for quick placement into the window casing without requiring on-site drilling or screwing operations
Solution Approach 2:
The patent eliminates the time-consuming drilling and screwing operations by using spring-loaded brackets that install through simple placement and automatic expansion, dramatically reducing installation time
3Ease of operation
If spring-loaded mounting brackets are used, then installation is faster and easier, but the spring force is insufficient for long or heavy window coverings, causing movement or creep
Solution Approach 1:
The patent employs spring-loaded mounting brackets with adjustable spring force that can be configured or replaced based on the weight and length of the window covering, allowing the system to dynamically adapt to different loading conditions while maintaining ease of installation
Solution Approach 2:
The spring force parameter can be changed or adjusted to match the specific requirements of different window covering weights and lengths, ensuring sufficient securing force without compromising installation ease
4Adaptability or versatility
If mounting brackets are installed on irregular windows, then window coverings can be installed, but the coverings become slack on one side due to irregularities in the window casing
Solution Approach 1:
The patent incorporates adjustable mounting mechanisms that allow the brackets to be positioned and adjusted to compensate for irregularities in the window casing, maintaining the window covering's levelness and stability across various window shapes and sizes
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 leveler system allows for easy, tool-free adjustment and secure installation of window coverings on irregular windows, ensuring a proper fit without damaging the casing and reducing installation time, while providing a stable compression fit for various window sizes and shapes.
Implementation Method 1
The threaded member is held by the bracket in an unthreaded manner to permit the threaded member to rotate relative to the bracket around an axis of the threaded member relative and without translating along the axis relative to the bracket. The ramp is threadably coupled to the threaded member such that rotation of the threaded member causes the ramp to translate relative to the threaded member along the axis of the threaded member.
Implementation Method 2
The guillotine member has a ramped shape at a lower edge, resembling a guillotine. The ramp and the guillotine member have corresponding ramped surfaces. Rotation of the threaded member causes the ramp to move along the axis of the threaded member, and movement of the ramp along the axis of the threaded member causes the guillotine member to move upwardly and downwardly along the track in the downwardly extending member.
Data Source
AI summary
A leveler for a window covering is disclosed. A fixed portion is secured to a headrail of a window casing, and moving portion is secured to the window covering. The moving portion is movable upward and downward relative to the fixed portion to allow for vertical adjustment of one end of the window covering relative to the window casing to straighten the window covering in the window.
