Vehicle Headlight Unit Sealing and Illumination Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle headlight units face challenges in maintaining a proper seal while allowing for adjustable illumination ranges and distinguishing between headlight and auxiliary lights, as through-holes for adjusting the reflector's angle compromise sealing performance.
Innovation Solution
A vehicle design featuring a headlight unit that rotates with respect to a cover, allowing adjustment of the headlight unit's angle without through-holes in the base member, and an auxiliary light cover configuration that maintains visibility and sealing by positioning the auxiliary light-use lens to protrude from the main lens, ensuring effective sealing and illumination adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If through-holes are formed in the base member to adjust the reflector's attachment angle, then the illumination range can be adjusted, but the sealing performance deteriorates
Solution Approach 1:
The patent applies the Dynamics principle by making the headlight unit rotatable relative to the cover through a support device. This allows the illumination range to be adjusted dynamically by rotating the entire headlight unit assembly, eliminating the need for through-holes in the base member and thereby maintaining sealing performance while achieving adaptability.
2Device complexity
If the auxiliary light-use lens is made contiguous with the main lens as a unit, then the structure is simplified, but the distinction between headlight and auxiliary light becomes difficult
Solution Approach 1:
The patent applies the Local quality principle by making the auxiliary light-use lens protrude from the main lens assembly. This creates a distinct local feature that allows visual differentiation between the headlight and auxiliary light functions, while the lenses remain structurally integrated. The protruding portion provides a unique visual characteristic that preserves function identification without requiring complete structural separation.
3Loss of information
If the auxiliary light-use lens protrudes from the main lens, then the auxiliary light is easier to distinguish, but the sealing complexity increases
Solution Approach 1:
The patent applies the Merging principle by integrating the auxiliary light-use lens as part of the headlight unit assembly that rotates together with the main lens. The auxiliary light-use lens protrudes from the main lens, and both are covered by a single cover that rotates with the headlight unit. This merging approach maintains sealing simplicity while achieving visual distinction through the protruding lens design.
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 solution ensures a sealed headlight unit while allowing for adjustable illumination ranges and clear distinction between headlight and auxiliary lights, reducing interference and enhancing recognition of the auxiliary light.
Implementation Method 1
The reflector is supported by the base member and reflects forward the light emitted from the headlight-use light emitter and the auxiliary light-use light emitter
Implementation Method 2
The lens forms part of the outer surface of the vehicle. The lens transmits light emitted from the headlight-use light emitter, light emitted from the auxiliary light-use light emitter, and light reflected by the reflector

AI summary
A vehicle comprising a headlight unit (56) having a lens made up of a main lens (503) and an auxiliary light-use lens (523), a cover (23) including an auxiliary light cover (232) surrounding at least part of the outer periphery of the auxiliary light-use lens (523), a support device supporting the headlight unit (56) on the cover (23) so that the angle by which the headlight unit (56) can rotate around a rotational axis extending in the left and right direction is greater than the angle by which the headlight unit (56) can rotate around a rotational axis extending in the up and down direction wherein the auxiliary light cover (232) is provided so that the distance from a left edge and a right edge to the auxiliary light-use lens (523) is less than the distance between an upper edge and the auxiliary light-use lens (523).
