Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector systems for flat surfaces and components lack ease of production, actuation, and effectiveness in securely connecting housings and other flat elements, with known solutions such as clamping connections and rod-shaped elements not providing sufficient bracing options.
Innovation Solution
A connector system comprising two bearing blocks with aligned openings and a connecting bolt with an eccentric head piece, where the bolt can only be inserted in a twisted position, interacting with a projection and recess, and featuring a stop and locking mechanism for secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional force-locking fasteners (screws, bolts, glues) are used to connect flat surfaces, then reliable connection is achieved, but ease of manufacture and ease of operation deteriorate due to complex assembly processes
Solution Approach 1:
The connector is divided into two separate bearing blocks that can be independently manufactured and then assembled. Each bearing block can be produced separately using standard manufacturing processes, and the final connection is made by inserting the connecting bolt through aligned openings in both blocks, simplifying the overall manufacturing process while maintaining connection reliability
Solution Approach 2:
The connecting bolt acts as an intermediary element that joins the two bearing blocks together. This intermediate component enables reliable connection between flat surfaces without requiring direct fastening methods, allowing for easier assembly and disassembly while maintaining structural integrity
2Ease of operation
If rod-shaped connection elements are inserted into slots to connect components, then ease of operation is improved, but bracing effectiveness and connection strength deteriorate
Solution Approach 1:
The connecting bolt features an asymmetric design with a projection on one end and a corresponding recess in the bearing block. This asymmetric geometry prevents the bolt from being inserted in incorrect orientations and ensures proper alignment, while the eccentric head piece creates mechanical advantage for secure engagement. The web-like projection provides additional bracing surfaces that enhance connection strength beyond simple slot insertion
Solution Approach 2:
The eccentric head piece is formed by an extension in a segment of a circle, creating a curved, cam-like surface that interacts with the bearing block opening. This curved geometry allows for smooth insertion while providing mechanical leverage for secure locking, combining ease of operation with enhanced bracing effectiveness through the eccentric rotational mechanism
3Ease of operation
If the connecting bolt can be inserted freely in any position, then ease of operation is improved, but connection precision and reliability deteriorate
Solution Approach 1:
The asymmetric projection-recess configuration on the connecting bolt and bearing block creates a self-aligning mechanism. The projection can only engage with the recess in a specific twisted position, automatically ensuring correct alignment during insertion. This eliminates the need for precise pre-alignment while maintaining connection precision, as the geometry itself guides proper positioning
Solution Approach 2:
The bearing blocks are pre-positioned with openings that are aligned with one another before the connecting bolt is inserted. This preliminary alignment of the bearing blocks, combined with the asymmetric bolt design, ensures that when the bolt is inserted, it automatically engages in the correct twisted position, maintaining both ease of operation and manufacturing precision
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
The system provides a simple and effective method to connect housings and flat elements, ensuring secure bracing and tension through the eccentric mechanism, enhancing the binding capabilities and ease of implementation.
Implementation Method 1
The connecting bolt has an eccentric head piece, which is formed by an extension in a segment of a circle. A corresponding opening in the bearing block can also be formed by an eccentric extension in a segment of a circle, so that both extensions interact with one another
Implementation Method 2
The connecting bolt can be twisted until it hits a stop element, which is provided according to a proposal of the invention. Furthermore, it can be locked in a position in a locking element.

AI summary
The present invention relates to a connector system comprising at least two bearing blocks (2, 3), each having an opening (6, 7) which can be attached relative to a surface and positioned such that the openings are aligned with each other, and a connecting bolt (8) which can be inserted into the mutually aligned openings to connect the bearing blocks (2, 3), wherein the connecting bolt and at least one opening have a matching pair of a projection and a recess, so that the connecting bolt can only be inserted into this opening in a specific rotational position.
