Solution Overview
Problem
The existing vehicle starting apparatus with integrated antenna coils for emergency starting methods faces design constraints due to excessive bezel thickness and package space requirements, and metallic button caps can interfere with antenna communication performance.
Innovation Solution
A vehicle starting apparatus with a cylindrical antenna assembly housing, a separate antenna coil for authentication, and a circuit board for electrical connection, allowing for reduced manufacturing processes and space usage, and enabling flexible design and material selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna coil is integrated into the start button, then the emergency starting function is achieved, but the bezel thickness becomes excessively large and the appearance is undermined
Solution Approach 1:
The antenna coil is separated from the start button and integrated into the inner panel. This segmentation allows the start button to have a smaller mounting hole and reduced bezel thickness, while the antenna coil maintains its emergency starting function independently within the inner panel structure.
2Reliability
If the antenna coil is integrated into the start button, then the emergency starting function is achieved, but the package space required is significant and acts as a design constraint
Solution Approach 1:
The antenna coil is merged with the inner panel structure, sharing the same mounting space. This integration eliminates the need for separate package space for the antenna coil, as it utilizes the existing inner panel cavity, thereby reducing overall volume requirements and removing design constraints.
3Shape
If the button cap is made of metallic material for high quality, then the appearance quality is improved, but the antenna communication performance cannot be secured due to shielding effect
Solution Approach 1:
The antenna coil is extracted from the start button assembly and integrated into the inner panel. This extraction removes the metallic button cap from the antenna's vicinity, eliminating the shielding effect that would otherwise block wireless communication between the antenna and the FOB key, while still allowing the button cap to be made of metallic material for aesthetic purposes.
