Window Balance Mounting Bracket for Secure Jamb Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window counterbalance systems face challenges in securely mounting and stabilizing the balance assemblies within window jamb channels, leading to potential disengagement and reduced functionality.
Innovation Solution
A window balance assembly comprising a carrier, a spring element, and a mounting bracket with specific configurations, including latches, head portions, and projections, which engage with the window jamb channel to provide secure installation and prevent unintentional disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple mounting bracket is used, then the device complexity is reduced, but the reliability of mounting the window balance assembly is compromised
Solution Approach 1:
The mounting bracket is divided into distinct functional segments: head portions for abutting the first wall, projections for engaging apertures in the second wall, and latches for securing the spring element. This segmentation allows each component to perform its specific function effectively, ensuring reliable mounting without requiring an overly complex integrated structure.
Solution Approach 2:
The latches are positioned within the bracket structure to engage the spring element, while the projections extend through the bracket body to engage the window jamb channel apertures. This nested arrangement allows multiple mounting functions to be integrated within a compact bracket design, maintaining reliability without excessive complexity.
2Reliability
If the mounting bracket includes multiple engagement features, then the reliability of preventing disengagement is improved, but the ease of installation is reduced
Solution Approach 1:
The projections are pre-configured on the bracket to align with the apertures in the window jamb channel, and the latches are pre-positioned to engage the spring element. This preliminary arrangement allows the installer to simply insert the bracket into the channel and secure it, with the engagement features automatically aligning and locking into place, maintaining ease of installation while ensuring reliable prevention of disengagement.
3Stability of the object's composition
If the spring element is securely latched, then the stability of the window balance assembly is improved, but the ease of repair is reduced
Solution Approach 1:
The latches are designed to be removable from the spring element, allowing the spring element to be extracted from the bracket for replacement or repair. This extraction capability maintains secure latching during normal operation for stability, while enabling easy removal when maintenance is required, thus balancing assembly stability with ease of repair.

AI summary
A window balance assembly may be in a window jamb channel to provide a biasing force urging a window sash toward an open position. The window balance assembly may include a carrier, a spring element and a mounting bracket. The spring element may include first and second portions. The first portion may be coupled to the carrier. The mounting bracket may include a latch, a first head portion, and a first projection. The latch may engage the second portion of the spring element. The first head portion may be configured to abut a first wall of the window jamb channel when the window balance assembly is installed in the window jamb channel. The projection configured to extend through and engage an aperture in a second wall of the window jamb channel when the window balance assembly is installed in the window jamb channel.
