Vehicle Door Glass Run With Magnetic Light Shield Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glass runs for vehicle doors burden occupants with difficult and potentially unsafe engagement mechanisms for light shields, narrowing vehicle space and causing pressure, and require time-consuming installation.
Innovation Solution
A glass run with a vehicle inner cover lip featuring a magnet or ferromagnetic material for easy engagement with a light shield, allowing expansion of vehicle space and reducing engagement burden, while ensuring safety through magnetic attraction or secure fitting mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the engagement member and engagement hole are engaged to attach the light shield, then the light shield can be secured in place, but the vehicle inner space is narrowed and occupants feel pressure
Solution Approach 1:
The engagement portion is repositioned from the vehicle inner side to the vehicle outer side of the glass run, changing the spatial dimension of engagement. This allows the light shield to be attached at a location that does not encroach on the vehicle inner space, thereby maintaining both attachment reliability and adequate interior volume.
2Reliability
If the support member is pulled upward and engaged with the engagement member, then the light shield can be attached, but the operation becomes burdensome and time-consuming
Solution Approach 1:
The manual engagement mechanism requiring upward pulling and precise positioning is replaced with a magnetic field-based attachment system. The magnetic attraction force automatically guides and secures the light shield to the glass run, eliminating the need for burdensome manual manipulation while ensuring reliable attachment.
3Reliability
If the engagement member is used for light shield attachment, then the light shield can be secured, but erroneous downward pulling may deform the engagement member or damage the engagement hole
Solution Approach 1:
The mechanical engagement system susceptible to deformation from erroneous forces is replaced with a magnetic field-based attachment system. The magnetic force provides secure attachment while being inherently more resistant to damage from improper handling, as magnetic components can withstand multidirectional forces better than precision mechanical engagement features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The glass run facilitates easy and safe attachment of light shields, expanding vehicle space, reducing engagement difficulty, and ensuring safety by using magnets or ferromagnetic materials for secure engagement.
Implementation Method 1
A vehicle inner cover lip is formed at a distal end of the vehicle inner side wall toward a vehicle inner side and toward a bottom wall, and the vehicle inner cover lip is formed with a shield engagement portion that is engaged with a light shield. The glass run facilitates easy and safe attachment of light shields, expanding vehicle space, reducing engagement difficulty, and ensuring safety by using magnets or ferromagnetic materials for secure engagement.
