Offset Fastening Element Layout for Tight Dashboard Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The restricted environment behind the dashboard in motor vehicles poses challenges in installing and securely fixing functional boxes, such as computers, due to limited space and the need to prevent damage from vibrations.
Innovation Solution
A fastening element comprising a first and second plate with connecting elements, where the first fixing means are positioned off-center relative to the second plate, allowing for manipulation and fixation without interference from surrounding architectural constraints, and utilizing existing fixing studs for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the first fixing means are positioned on the first plate facing the second plate, then the fixation structure is compact, but the manipulation of fixing means is blocked by surrounding architectural constraints
Solution Approach 1:
The first fixing means are positioned on the first plate in a location that is not opposite the second plate in the predetermined fixing direction. This spatial repositioning allows the fixing means to be manipulated from the side of the second plate, effectively using a different spatial dimension for access while maintaining a compact overall profile of the fastening element.
2Area of stationary object
If the fastening element is designed to fit in restricted space, then it can be installed in driving position, but the fixing means become difficult to access and manipulate
Solution Approach 1:
The fastening element maintains a compact profile suitable for restricted installation spaces while positioning the first fixing means laterally offset from the second plate. This allows technicians to access and manipulate the fixing means from the side of the second plate, effectively using lateral space for operation while keeping the forward profile compact.
Solution Approach 2:
The asymmetric positioning of the first fixing means relative to the second plate creates an offset configuration where the fixing means are located on parts of the first plate that are not opposite the second plate. This asymmetry provides access pathways around the compact structure, enabling manipulation in restricted environments.
3Reliability
If the functional box is fixed rigidly to prevent vibrations, then it is protected from damage, but the installation complexity increases in restricted environments
Solution Approach 1:
The fastening element is divided into two separate plates (first and second plates) connected by connecting elements. This segmentation allows the fixing means to be distributed on different surfaces, providing access from the side of the second plate while maintaining rigid fixation of the functional box to prevent vibrations.
Solution Approach 2:
By positioning the fixing means laterally offset rather than directly facing, the design provides access pathways that simplify installation in restricted environments while the rigid connection between plates ensures vibration protection.
