Window shelf assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window shelf devices require permanent attachment to the sill for stable object display, limiting flexibility and aesthetics.
Innovation Solution
A window shelf assembly comprising a first bracket on the sill with coupled bars and a second bracket with a movable arm that abuts the wall, creating a horizontal support surface without permanent attachment, using abrasive and resilient materials for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent attachment to window sill is used, then stability of object display is improved, but flexibility and aesthetics are worsened
Solution Approach 1:
The shelf assembly transitions from a static permanent attachment to a dynamic removable configuration. The brackets are designed to be positionable on the window sill rather than permanently fixed, allowing the shelf to be installed and removed as needed. This dynamic approach maintains stability during use while providing flexibility for installation and removal.
Solution Approach 2:
The bracket assembly acts as an intermediary between the window sill and the shelf surface. The brackets provide a mediating connection that distributes weight and provides secure engagement without requiring permanent attachment to the sill, resolving the contradiction between stability and flexibility.
2Reliability
If permanent structure attachment is used, then stable support is improved, but aesthetic appearance is worsened
Solution Approach 1:
The shelf system uses removable brackets that can be installed only when needed, rather than permanent structures that are always visible. This allows the window area to maintain its aesthetic appearance when the shelf is not in use, while still providing stable support when the shelf is installed.
Solution Approach 2:
The support function is extracted from a permanent structural attachment and separated into removable bracket components. This allows the support mechanism to be present only when needed for displaying objects, rather than being a permanent visual element that compromises aesthetics.
3Adaptability or versatility
If removable configuration is used, then flexibility and aesthetics are improved, but stable support is worsened
Solution Approach 1:
The brackets are designed with positioning features that allow easy installation and removal while providing stable support when installed. The dynamic nature of the removable configuration is compensated by design features that ensure firm engagement during the display period.
Solution Approach 2:
The bracket assembly serves as an intermediary that translates the removable configuration into stable support. The brackets distribute the weight of displayed objects across multiple contact points with the window sill, providing stable support despite the removable nature of the assembly.
4Ease of operation
If simple bracket design is used, then ease of installation is improved, but secure engagement is worsened
Solution Approach 1:
The shelf system is segmented into separate bracket components that can be independently positioned and installed. This segmentation allows for simple installation of individual brackets while the collective arrangement of multiple brackets provides secure engagement for the shelf and displayed objects.
Solution Approach 2:
The brackets act as intermediary components that simplify installation while ensuring secure engagement. The bracket design includes features that facilitate easy positioning on the window sill while maintaining firm engagement to support the shelf and its contents.
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
Enables flexible and aesthetically pleasing display of objects without permanent structure attachment, allowing for easy adjustment and secure support of items like holiday ornaments.
Implementation Method 1
each of the first surface 21 and the second surface 23 comprise an abrasive material for frictionally engaging the window sill 14
Implementation Method 2
A pad 60 is coupled to the second surface 58 of the foot 54 such that the pad 60 abuts the wall 44. The pad 60 is comprised of a resilient material to frictionally engage the wall 44.

AI summary
A window shelf assembly for displaying an object in on a window sill includes a first bracket that is positionable on a window sill. A plurality of bars is provided and each of the bars is coupled to the first bracket. A second bracket is provided and each of the bars is coupled thereto such that the second bracket is spaced from the first bracket. An arm is movably disposed on the second bracket. The arm abuts a wall in which the window is positioned for supporting the bars on a horizontal plane to define a support surface for displaying an object.
