Wedge With Undercut Connecting Means For Adjustable Pack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wedges for compensating and bridging distances in construction lack an efficient and versatile mechanism for forming a wedge pack with wedges of the same shape, particularly in terms of arbitrary mutual orientation and adjustable wedge angle.
Innovation Solution
The wedge design features connecting means with undercut sections and projections that allow for a form-fitting adhesive connection between wedge surfaces, enabling the assembly of multiple wedges into a pack with adjustable thickness and orientation, using a push-pull or plug-and-slide movement, and featuring sawtooth profile zones for latching and elastic deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connecting means are used without undercut sections, then the wedge surfaces can be easily assembled, but the connection lacks secure adhesion and form-fitting engagement
Solution Approach 1:
The connecting means are segmented into distinct undercut sections and undercut-free zones along the side walls of grooves and ribs. This segmentation allows different portions of the connecting means to serve different functions: undercut sections provide secure adhesion through form-fitting engagement, while undercut-free zones enable easy insertion and assembly.
Solution Approach 2:
Different portions of the connecting means have different geometric qualities. The undercut sections feature overhanging side walls that create interference fits for secure connection, while the undercut-free zones have simple open geometries that facilitate easy insertion. This local differentiation of geometric properties resolves the contradiction between secure connection and ease of assembly.
2Adaptability or versatility
If multiple wedges are assembled into a wedge pack with arbitrary orientation, then the wedge pack achieves adjustable thickness and orientation, but the assembly complexity increases
Solution Approach 1:
The connecting means are designed with symmetry and standardized features (undercut sections at specific positions on grooves and ribs) that allow wedges to be assembled in multiple orientations (parallel or anti-parallel) using the same connection mechanism. This universal design enables arbitrary orientation and adjustable wedge pack configuration without requiring different connecting means for different assembly modes, thus avoiding increased assembly complexity.
3Reliability
If undercut sections are provided on all side walls of grooves and ribs, then secure form-fitting connection is achieved, but the insertion difficulty increases and assembly becomes more complex
Solution Approach 1:
Undercut sections are provided only at specific locations (e.g., at the ends or specific portions) of the grooves and ribs, not on all side walls throughout their entire length. This local application of undercut features provides sufficient form-fitting engagement for secure connection while leaving other portions open for easy insertion, thus resolving the contradiction between connection security and insertion ease.
Solution Approach 2:
Instead of providing undercut sections on all side walls of grooves and ribs (excessive action), undercut sections are provided only at the necessary locations to achieve secure form-fitting connection (partial action). This partial application of the undercut feature achieves the required connection reliability without the excessive complexity and insertion difficulty that would result from complete coverage.

Function Achieved in This Case
This design allows for the creation of a wedge pack with adjustable thickness and orientation, enabling flexible assembly and disassembly, while ensuring secure adhesion and easy release, facilitating the formation of parallel surfaces or increased wedge angles.
Implementation Method 1
The material of the wedges lying against one another is preferably so elastic that the latching force is generated by elastic deformation of the wedges
