Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If light-emitting diodes are used in vehicle headlight systems, then energy efficiency and lifespan are improved, but tolerance requirements and installation complexity increase significantly
Solution Approach 1:
The adjustment element automatically maintains the optical settings when the mounting element is removed and reinstalled. The memory function allows the system to self-retain the adjusted position without requiring manual re-adjustment, thus resolving the contradiction by reducing the impact of tolerance requirements through automatic position retention.
Solution Approach 2:
The system changes the state of the adjustment element from fixed to movable during adjustment, and back to fixed when retaining settings. This parameter change allows the system to adapt between precise positioning mode and setting retention mode, addressing the tolerance issue while maintaining LED lifespan benefits.
2Reliability
If optical components are adjusted to meet legal light image requirements, then lighting performance is improved, but adjustment time and operational complexity increase
Solution Approach 1:
The adjustment element with memory function automatically retains the optical settings, allowing the system to self-maintain compliant lighting performance without requiring repeated manual adjustments. This eliminates time loss when changing mounting elements while ensuring lighting performance requirements are met.
Solution Approach 2:
The system performs the adjustment action in advance and stores the setting in the adjustment element. When the mounting element is replaced, the pre-stored settings are automatically applied, eliminating the need for time-consuming re-adjustment while maintaining legal light image requirements.
3Ease of repair
If the mounting element is removed and replaced, then light-emitting diode replacement is enabled, but optical settings are lost and must be re-adjusted
Solution Approach 1:
The adjustment element automatically retains and restores optical settings without human intervention. When the mounting element is replaced, the system self-restores the previous settings, enabling easy LED replacement while eliminating the cumbersome re-adjustment process.
Solution Approach 2:
The adjustment element creates a memory copy of the optical settings. When the mounting element is replaced, this copied setting information is transferred back to the optical element, allowing LED replacement without loss of optical configuration and eliminating re-adjustment effort.
4Ease of repair
If coupling elements are designed to be detachable for mounting element replacement, then ease of replacement is improved, but maintaining precise optical alignment becomes more difficult
Solution Approach 1:
The adjustment element with memory function automatically compensates for potential misalignment when detachable coupling elements are used. The system self-restores the precise optical alignment by recalling the stored settings, thus maintaining alignment precision while preserving the ease of replacement benefit.
Solution Approach 2:
The adjustment element acts as an intermediary that stores and transfers alignment information between the mounting element and the optical element. This mediator ensures that precise optical alignment is maintained during detachable coupling operations, resolving the contradiction between ease of replacement and alignment precision.

AI summary
The invention relates to a mounting system for mounting light-emitting diodes (LEDs) in a housing (GEH) of a lighting unit or a vehicle headlight, wherein the mounting system (SYS) comprises a mounting element (MON) on which the LEDs (LEDs) and an optical element (SPI) are arranged, through which light from the LEDs (LEDs) is emitted into the external space of the lighting unit/headlight. The optical element (SPI) is pivotable about a pivot axis (ACH) relative to an adjustment element (KOP), wherein a translational movement of the adjustment element (KOP) is converted into a pivot movement of the optical element (SPI) about its pivot axis (ACH), and wherein the optical element (SPI) can be fixed such that when the mounting element (MON) is removed, the first coupling element (KOP1) remains in the coupled position.
