Hinge Holding Piece Groove Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window hinges face limitations in adjustment range and flexibility, particularly when using hinge parts with protruding fastening pins, as they require specialized designs and limited adjustment options within the hinge pocket.
Innovation Solution
The design incorporates a holding piece that receives and fixes fastening pins or webs, interacting with adjusting elements and bolts, allowing for adjustable and pivotable mounting within the hinge pocket without the need for a precisely fitting ribbon-like tab, enabling horizontal and vertical adjustments without disassembling the door or window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If hinge parts with protruding fastening pins are used, then the hinge can be easily assembled, but the adjustment range and flexibility are limited
Solution Approach 1:
The hinge is divided into separate functional components: a holding piece with multiple groove-like depressions for receiving fastening pins, and a hinge part with protruding fastening pins. This segmentation allows the holding piece to remain stationary while the hinge part can be adjusted and repositioned along the grooves, providing both easy assembly and adjustable positioning.
Solution Approach 2:
The holding piece is designed with groove-like depressions that allow the hinge part to be dynamically repositioned. The grooves provide guided movement paths, enabling the hinge to be adjusted to different positions while maintaining secure connection through the fastening pins engaging with the grooves.
2Adaptability or versatility
If a specialized ribbon-like tab configuration is used in the hinge pocket, then adjustment functions are enabled, but the device complexity increases
Solution Approach 1:
Instead of making the hinge part complex with integrated adjustment mechanisms, the invention inverts the approach by providing adjustment capability through the holding piece's groove-like depressions. The standard hinge part with simple fastening pins engages with the specially configured holding piece, reversing which component carries the complexity.
Solution Approach 2:
The holding piece with groove-like depressions serves multiple functions: it receives and secures the fastening pins, provides adjustment capability along the groove paths, and maintains structural support. This multi-functional design eliminates the need for separate adjustment mechanisms, reducing overall device complexity.
3Stability of the object's composition
If the hinge part is fixed in the hinge pocket, then stability is achieved, but adjustment possibilities are lost
Solution Approach 1:
The holding piece is pre-configured with groove-like depressions that define possible adjustment positions. The fastening pins are designed to engage with these pre-defined grooves, allowing the hinge to be securely fixed at any position along the grooves. This preliminary configuration enables both stability when fixed and adjustability when repositioning.

AI summary
The hinge has a hinge part (3) with retaining piece (5), which engages in a band case (4). The retaining piece is provided with axle bolts, which engage in guidance of the band case at its end area, which is opposite to the insertion area. The piece is formed for receiving and for fixing of fastening pins (8) or bars. The piece has adjustment unit, which works together with the bolts and pins and supported in the case.
