Angled Bracket Mounting Structure for Compact Vehicle Installations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-mounted device-fixing structures have a large outer dimension in planar view, which can be a challenge for compact vehicle designs.
Innovation Solution
The proposed vehicle-mounted device-fixing structure includes a vehicle-mounted device, a first bracket with a first fastening member, and a second bracket with a second fastening member. The first and second fastening members have contact surfaces that form an obtuse angle, allowing for a reduced outer dimension in planar view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conventional brackets are used to fix the vehicle-mounted device to the floor panel and cross member, then the device is securely mounted, but the outer dimension of the structure in planar view becomes large
Solution Approach 1:
The patent changes the orientation of the contact surfaces from a conventional parallel arrangement to an obtuse angle arrangement. This dimensional change in the angular configuration allows the fastening members to be positioned closer together in planar view while still providing secure mounting through the angled contact surfaces that distribute loads more effectively.
Solution Approach 2:
The patent modifies the geometric parameter of the contact surfaces by setting the angle between them to an obtuse angle rather than the conventional parallel or acute angle configuration. This parameter change enables the structure to achieve compact planar dimensions while maintaining mounting reliability through the optimized angular geometry that improves force distribution.
2Area of stationary object
If the brackets extend forward and backward from the device, then secure fastening is achieved, but the overall structure occupies more space in planar view
Solution Approach 1:
The patent transitions from a linear extension configuration of brackets to an angular configuration where contact surfaces meet at an obtuse angle. This dimensional reconfiguration reduces the planar footprint area while the obtuse angle geometry provides sufficient leverage and contact area for secure fastening, effectively solving the space occupation problem.

AI summary
The vehicle-mounted device-fixing structure includes a vehicle-mounted device, a first bracket that is fixed to the vehicle-mounted device, and a second bracket that is fixed to the vehicle-mounted device. The first bracket has a first fastening member that is fastened to a first fastening surface provided on a vehicle. The second bracket has a second fastening member that is fastened to a second fastening surface provided on the vehicle. The first fastening member includes a first contact surface that contacts the first fastening surface, and the second fastening member includes a second contact surface that contacts the second fastening surface. An angle formed between the first contact surface and the second contact surface is an obtuse angle.
