Solution Overview
Problem
The existing radiator grille charging door apparatus for electric vehicles is prone to damage and separation from the vehicle body when an external force is applied, and may cause injury to pedestrians during collisions due to its design.
Innovation Solution
A radiator grille charging door apparatus featuring a hinge shaft, hinge connector, hinge bracket, and hinge springs that allow the charging door to rotate and absorb external forces, with a sliding and locking mechanism to prevent separation and enhance safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed part structure is used to rotate the charging door, then the door can be opened and closed, but the fixed part may be damaged when external force is applied laterally
Solution Approach 1:
The patent transforms the static fixed part structure into a dynamic hinge connector structure that can rotate and deform. The hinge connector includes a first rotating part that rotates about a fixed shaft and a second rotating part that rotates about the hinge shaft, allowing the structure to adapt dynamically to external forces rather than remaining rigid and vulnerable to damage.
Solution Approach 2:
The patent changes the structural parameters of the connection mechanism by introducing multiple rotating parts with different rotation axes. The hinge connector can change its configuration from a rigid fixed part to a flexible articulated structure, altering its mechanical properties to resist lateral forces while maintaining rotational functionality.
2Strength
If a robust design with reinforcing rib is used to prevent door separation, then the door strength is improved, but pedestrian safety is compromised during collision
Solution Approach 1:
The hinge connector provides dynamic strength through its articulated structure with multiple rotating parts. Instead of using a rigid reinforcing rib that could injure pedestrians, the patent employs a flexible linkage mechanism that maintains connection strength while allowing controlled movement and deformation during impact, reducing harmful effects on pedestrians.
Solution Approach 2:
The patent changes the structural configuration from a rigid reinforcing rib to an articulated hinge mechanism. This parameter change allows the connection to maintain sufficient strength for normal operation while providing flexibility during collision to reduce pedestrian injury risk.
3Volume of moving object
If the charging door structure is positioned in the radiator grille, then space utilization is improved, but the door becomes vulnerable to external forces
Solution Approach 1:
The patent positions the charging door in the radiator grille space and employs the hinge connector with rotating parts to provide dynamic stability. The articulated structure adapts to external forces through rotation and deformation, maintaining reliability despite the constrained position in the radiator grille.
Solution Approach 2:
The patent changes the mechanical parameters of the door connection by introducing the hinge connector mechanism, transforming the door from a statically vulnerable component to one with dynamic stability characteristics that accommodate both space constraints and external force resistance.
