Vehicle Display Mount With Pivoting Preassembly Hinge
Solution Overview
Problem
The assembly of vehicle operating units, particularly the fastening of displays, is complex and time-consuming due to the need for precise alignment and secure mounting of multiple components.
Innovation Solution
An operating unit design featuring a housing with a front panel recess, a pivotable holding part for the display, and a fastening device with a bearing axle and separable hinge mechanism, allowing for simplified display mounting by pivoting the holding part from a preassembly to an installation position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods are used to secure the display in the housing, then the display is firmly fixed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The holding part is designed to be pivotable between a preassembly position and an installation position, transforming a static fastening structure into a dynamic one that simplifies assembly. The bearing axle enables rotational movement, allowing the holding part to be easily positioned during assembly and then secured in the installation position.
Solution Approach 2:
The fastening device is divided into separate components: a holding part for the display, a bearing axle, and bearing shell assemblies. This segmentation allows each component to be independently assembled and positioned, reducing overall assembly complexity while maintaining secure mounting.
2Reliability
If multiple components are used for fastening the display, then the mounting is secure, but the assembly time increases
Solution Approach 1:
The bearing shell assemblies are pre-positioned on the bearing axle in a preassembly position, allowing the holding part to be mounted on the bearing axle before final installation. This preliminary arrangement of components significantly reduces assembly time while maintaining secure fastening through the subsequent pivoting action that engages the abutting elements.
3Reliability
If the holding part is fixed in position, then the display is securely mounted, but the assembly process requires precise alignment
Solution Approach 1:
The pivotable holding part eliminates the need for precise alignment during assembly. The bearing axle and bearing shell assemblies provide guided rotational movement, allowing the holding part to be easily positioned and then secured in the installation position without requiring high precision alignment operations.
4Productivity
If a simple fastening structure is used, then assembly is quick, but the display mounting becomes unreliable
Solution Approach 1:
The fastening device is segmented into a holding part, bearing axle, and bearing shell assemblies that work together through a pivotable connection. This segmented design achieves both quick assembly through the pivotable mechanism and reliable mounting through the cooperative interaction of the segmented components.
Solution Approach 2:
The dynamic pivotable connection between the holding part and housing provides both assembly simplicity and mounting reliability. The movement from preassembly to installation position enables quick assembly, while the engagement of abutting elements in the installation position ensures secure and reliable display mounting.

AI summary
The operating unit (10) for a vehicle is provided with a housing (12) with a front panel (14), which has a recess (16), a display (24) arranged in the housing (12) and having a display area (26), and a fastening device (36) for fastening the display (24) in the housing (12). The fastening device (36) has a holding part (28) for the display (24), which is arranged in the housing (12) so as to be pivotable between a preassembly position and an installation position. The housing (12) also has at least one bearing axle (40). The holding part (28) has at least one bearing shell assembly (32) having at least two gripping-around protrusions (48, 50) for mounting on the bearing axle (40). The bearing axle (40) has a circumferential area along the longitudinal extent and in at least one mounting portion (57) with an outer contour which deviates from a shape complementary to the bearing shell area (52) of the gripping-around protrusions (48, 50) of the at least one bearing shell assembly (32). The bearing axle (40) is also arranged in the housing (12) so as to be oriented in such a way that the at least one bearing shell assembly (32) can be mounted on the bearing axle (40) in the preassembly position of the holding part (28) and, starting from the preassembly position, is pivotable into the installation position. The installation position of the holding part (28) is defined by bearing parts (60, 34) of the housing (12) and holding part (28) abutting on each other. The fastening device also has at least one fastening element (58) for fixing the holding part (28) in its installation position in and/or on the housing (12).
