Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitting arrangements for hinge-mounted components, such as folding shutters and doors, are cumbersome and limited in adjustability, especially on upper floors, and often require specific frame designs, which can lead to structural issues with materials like wood due to shear strength concerns.
Innovation Solution
A fitting arrangement featuring a gripping element with a tension member and sliding block mechanism that allows for adjustable attachment to the component frame from the inside, enabling precise and stable adjustment without visible disturbances, suitable for various materials including wood, metal, and plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fitting arrangement uses a base plate with holes or slots and guide elements that can be screwed to the frame, then the component can be adjusted in different positions, but the adjustment becomes cumbersome and difficult, especially on upper floors
Solution Approach 1:
The invention transforms the static screw-adjustment mechanism into a dynamic tension-based system. The tension member with gripping elements allows the receiving element to be easily held and adjusted in position, converting the complex multi-step screw adjustment into a simple tensioning action that can be performed from inside the building, especially on upper floors.
Solution Approach 2:
The invention introduces a tension member as an intermediary element between the base plate and the receiving element. This tension member with its gripping elements acts as a mediator that simplifies the adjustment process, allowing the receiving element to be easily positioned and held without requiring direct manipulation of multiple screws or guide elements.
2Manufacturing precision
If a fitting arrangement uses holding arms that grip grooves from behind, then precise positioning is achieved, but the fittings cannot be used for wooden folding shutters because the edges could break out due to low shear strength
Solution Approach 1:
The invention introduces a tension member as an intermediary that distributes forces more evenly across the frame. Instead of concentrating forces at edge grip points that could cause wood to break out, the tension member spreads the loading across a larger area, protecting the frame material from localized stress concentrations while maintaining positioning precision.
Solution Approach 2:
The invention changes the force distribution parameter by using a tension member that extends through the frame. This transforms the force application from edge-concentrated (which causes breaking) to distributed (which preserves strength), allowing the same precision mechanism to work on various frame materials including wood without compromising shear strength.
3Ease of operation
If a fitting arrangement allows adjustment from the inside of the building, then convenience is improved, but the adjustment mechanism becomes more complex
Solution Approach 1:
The invention segments the adjustment mechanism into distinct functional components: a base plate for mounting, a tension member for force transmission, and a receiving element for positioning. This segmentation allows each component to perform its specific function efficiently, enabling inside adjustment without requiring an overly complex integrated mechanism.
Solution Approach 2:
The invention uses a dynamic tension-based adjustment mechanism that can be operated from inside the building. The tension member with gripping elements allows the receiving element to be easily positioned and held, converting what would otherwise be a complex multi-component adjustment system into a simpler, more maintainable design that prioritizes ease of operation.

Facilitates simple and convenient adjustment of hinge-mounted components on upper floors and diverse frame types, ensuring stable fixation without compromising the structural integrity of the frame material.
Implementation Method 1
the fixing means have a gripping element by means of which the receiving element can be held on the base element perpendicularly to a first and a second direction of displacement, the gripping element being held on a tension member which has a length which is dimensioned such that it extends away from the receiving element
