Window Regulator Bracket Rotation for Guide Member Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing window regulator designs face difficulties in assembly due to the narrow space between the inner and outer panels, where the guide members must be mounted against the urging force of the slack preventing means, making the process cumbersome and challenging.
Innovation Solution
A window regulator design featuring a bracket with a rotatable end portion and a guide member at its midsection, allowing easy alignment and mounting of guide members on the inner panel by rotating the bracket against the slack preventing force, along with a jig for facilitating the assembly process, which reduces the required force and space needed for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide members are mounted against the urging force of the slack preventing means in the narrow space between inner and outer panels, then the window regulator can be assembled with proper wire tension, but the assembly process becomes difficult and cumbersome
Solution Approach 1:
The bracket is pre-positioned on the inner panel before mounting the guide members. This preliminary positioning creates space and leverage points that make it easier to subsequently install the guide members against the slack preventing means' urging force, without requiring excessive force or complex maneuvers in the confined space
Solution Approach 2:
The bracket serves as an intermediary component between the inner panel and the guide members. It provides a mounting structure that facilitates the installation of guide members by creating mechanical advantage and proper positioning, making the assembly process easier while maintaining the necessary wire tension
2Ease of operation
If a bracket with rotatable end portion and midsection guide member is used, then assembly requires minimal force and space, but the bracket structure becomes more complex
Solution Approach 1:
The bracket incorporates a rotatable end portion that allows dynamic adjustment during assembly. This rotational capability enables the bracket to be positioned and aligned more easily in the confined space, reducing the force required for assembly while the guide member at the midsection provides stable mounting for the wire guidance component
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
This design enables easier assembly of the window regulator by allowing the guide members to be mounted with minimal force and space, improving assembly efficiency and applicability to doors with smaller panel thicknesses, while also providing a compact solution that reduces dead space on the inner panel.
Implementation Method 1
a resilient member (coil spring) configured to urge the tube in the extending direction
Implementation Method 2
rotating the bracket against the urging force of the slack preventing means about the engaging portion as a center of rotation
