Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different types of lamps are incorporated into the door mirror, then the versatility and functionality of the door mirror is improved, but the manufacturing cost increases due to the need for separate die molds for each lamp type
Solution Approach 1:
The patent applies universality by designing a single standardized lamp attaching portion that can accommodate multiple types of lamps (lighting lamps, projection lamps, etc.). The bracket is designed with a universal structure that can be used across different door mirror models, allowing the same housing part to support various lamp types without requiring separate die molds for each lamp configuration.
Solution Approach 2:
The patent utilizes parameter changes by allowing the optical axis inclination of the bracket to be adjusted or varied while maintaining the same basic bracket structure. This enables different lamp types with different optical requirements to be mounted on the same standardized attaching portion, achieving versatility without increasing manufacturing complexity.
2Manufacturing precision
If separate housing parts are formed for each lamp type, then the optical precision and performance for each lamp is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent employs universality by creating a standardized lamp attaching portion that serves multiple functions: it provides mechanical support, optical axis alignment, and mounting for different lamp types. The bracket is designed as a universal component that can be attached to a common housing part, eliminating the need for separate housing variants while maintaining precise optical alignment for different lamp types.
Solution Approach 2:
The bracket acts as an intermediary component between the standardized housing part and the various lamp types. It provides the necessary optical axis alignment and mechanical attachment functionality, allowing different lamps to be mounted on the same housing without requiring custom housing parts for each lamp type.
3Ease of manufacture
If a common bracket is used for different lamp types, then the ease of manufacture is improved, but the ability to optimize optical axes for each lamp type is reduced
Solution Approach 1:
The patent applies dynamics by making the bracket's optical axis inclination adjustable or variable rather than fixed. This allows the bracket to be adapted for different lamp types with different optical requirements while maintaining the same basic bracket structure, thus achieving both manufacturing efficiency and optical optimization.
Solution Approach 2:
The patent utilizes parameter changes by allowing the optical axis inclination angle of the bracket to be varied or adjusted depending on the lamp type being installed. This enables a single standardized bracket design to accommodate multiple lamp types with different optical characteristics, maintaining manufacturing simplicity while achieving optimal optical performance for each application.

AI summary
To provide a technique that relates to a door mirror and/or a door mirror manufacturing method and allows incorporation of different types of lamps while suppressing an increase in cost. A door mirror for a vehicle includes a lamp attaching portion, a first lamp attached to the lamp attaching portion via a bracket, and a housing cover having an optical opening through which light emitted from the first lamp is transmitted. A second lamp different in lighting characteristics from the first lamp is attachable to the lamp attaching portion as an alternative to the first lamp. The bracket causes an optical axis of the first lamp while the first lamp is attached to the lamp attaching portion to be inclined in a direction different from a direction in which an optical axis of the second lamp is inclined when the second lamp is alternatively attached to the lamp attaching portion.
