Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shims used in window and door installations lack flexibility and precision in adjusting distances between components, leading to inefficiencies and potential misalignment issues.
Innovation Solution
A shim assembly comprising a first and second plate with inward tapered surfaces, a wedge assembly, and a fastener that allows for adjustable distance control between the plates, facilitated by a guide mechanism to ensure precise alignment and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional shims are used for window and door installations, then the installation process is simple, but the adjustment precision and flexibility are insufficient
Solution Approach 1:
The shim assembly is divided into multiple functional components: first plate, second plate, wedge assembly, and fastener. Each component serves a specific function in the adjustment process, allowing for precise control while maintaining a modular structure that doesn't overly complicate the overall system.
Solution Approach 2:
The shim assembly transitions from a static traditional shim to a dynamic adjustable system. The wedge assembly can be moved along the tapered surfaces of the plates, and the fastener can be rotated to lock at different positions, enabling continuous adjustment of the distance between the first and second plates to achieve precise alignment.
2Manufacturing precision
If multiple shims are used to achieve proper fit and alignment, then adjustment precision improves, but the number of components and installation complexity increase
Solution Approach 1:
The single shim assembly performs multiple functions that would otherwise require multiple separate shims: it provides spacing, enables precise adjustment through wedge movement, secures components with the fastener, and guides alignment through the tapered surfaces. This multi-functional design replaces the need for multiple individual shims.
Solution Approach 2:
The wedge assembly is nested within the space between the first and second plates. The fastener passes through the wedge assembly to secure it. This nested arrangement allows multiple functional elements to be integrated within a compact structure, reducing the overall number of separate components needed.
3Adaptability or versatility
If traditional shims are used, then the structure is simple, but the ability to dynamically adjust distance and maintain alignment is limited
Solution Approach 1:
The shim assembly incorporates dynamic adjustment capability through the wedge assembly that can be positioned at different locations along the tapered surfaces. The fastener can be rotated to lock the wedge at various positions, allowing the distance between plates to be dynamically adjusted and maintained according to specific alignment requirements.
Solution Approach 2:
The tapered surfaces of the plates and wedge assembly enable parameter changes in the distance between the first and second plates. By moving the wedge along the tapered surfaces and securing it at different positions with the fastener, the spacing parameter can be continuously adjusted to achieve the desired alignment and fit.

AI summary
Shim assemblies and related windows and doors are disclosed. An apparatus includes a shim assembly including a first plate and a second plate movably coupled together, and a wedge assembly. Each of the first plate and the second plate includes a first end including a first inward tapered surface and a second end including a second inward tapered surface. A wedge assembly includes a first wedge engaging the first inward tapered surfaces of the first plate and the second plate, a second wedge engaging the second inward tapered surfaces of the first plate and the second plate, and a fastener passing through the first wedge, between the first plate and the second plate, and threadably engaging the second wedge. Rotating the fastener changes a distance between the first wedge and the second wedge and changes a distance between the first plate and the second plate.
