Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching displays to vehicles, such as adhesives and magnets, face issues like damage to vehicles, difficulty in maintaining attachment at high speeds, and inability to stick to non-ferromagnetic surfaces, leading to aerodynamic inefficiencies and stress concentrations.
Innovation Solution
A system utilizing hook-and-loop or magnetic coupling mechanisms positioned within depressions on a display to securely attach to a window, with a failsafe mechanism and protective elements to prevent damage, allowing easy attachment and detachment while minimizing air gaps and drag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If strong adhesives are used to attach displays to vehicles, then the display attachment strength is improved, but the vehicle surface is damaged and removal time increases
Solution Approach 1:
The coupling system is divided into separate components: a first coupling mechanism attached to the display and a second coupling mechanism attached to the window. This segmentation allows the display to be securely attached through mechanical interlocking (hooks and loops) rather than strong adhesives, enabling easy removal without damaging the vehicle surface.
Solution Approach 2:
The coupling mechanisms are designed to be reusable and non-damaging. The hook-and-loop system allows the display to be repeatedly attached and detached without degrading the vehicle surface, unlike strong adhesives that leave residue or damage when removed.
2Ease of operation
If conventional magnets are used to display signage, then the display can be easily attached and removed, but the magnetic force is insufficient at high speeds and non-ferromagnetic surfaces cannot be attached
Solution Approach 1:
The system transitions from magnetic coupling to mechanical coupling (hooks and loops). This parameter change in the coupling mechanism provides reliable attachment at high speeds by using physical interlocking structures that are not affected by speed-related forces or surface material properties.
Solution Approach 2:
The hook-and-loop coupling system is universal and can be attached to any non-ferromagnetic surface (unlike magnets). The second coupling mechanism with protective elements can be adhered to various window surfaces, making the system versatile for different vehicle types and window materials.
3Adaptability or versatility
If displays are attached to vehicle windows, then vehicle signage functionality is improved, but aerodynamic drag increases and stress concentrations occur
Solution Approach 1:
The first coupling mechanism is positioned within a depression formed in the display surface. This nesting arrangement allows the coupling elements to be recessed into the display, creating a coplanar outer surface that minimizes aerodynamic drag and prevents stress concentrations when the display is attached to the window.
Solution Approach 2:
The depression is specifically shaped to correspond with the first coupling mechanism, creating a localized feature that houses the coupling elements. This local modification allows the rest of the display surface to remain smooth and aerodynamic, maintaining vehicle performance while enabling signage functionality.
4Strength
If coupling mechanisms are positioned on the display surface, then secure attachment is achieved, but air gaps are created between the display and window
Solution Approach 1:
The first coupling mechanism is nested within a depression in the display, and the second coupling mechanism is nested within a corresponding depression in the window. This dual nesting approach allows the coupling elements to be recessed on both sides, eliminating air gaps and creating a coplanar surface that maintains aerodynamic properties.
Solution Approach 2:
The solution moves the coupling mechanisms from a surface-level attachment to a recessed, three-dimensional configuration. By positioning the coupling elements within depressions rather than on the outer surface, the system eliminates the air gap problem while maintaining secure attachment through the interlocking hook-and-loop mechanisms.
