Lamp Holder Spring with Positioning Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamp holder devices for vehicles are prone to incorrect assembly due to the high flexibility of the locking spring, leading to improper light distribution and difficulty in replacing headlight lamps in cramped engine compartments, where visibility is poor.
Innovation Solution
A fork-shaped, elastically deformable spring-like member with elastic contrasting means that prevents locking when the lamp is not correctly positioned, ensuring it can only snap into place when aligned correctly with the seat and reflector, thus preventing incorrect assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible locking spring is used in the lamp holder device, then the lamp can be easily locked into position, but the lamp may be locked in incorrect positions as well
Solution Approach 1:
The spring-like member is designed with differentiated local properties: a flexible portion for easy locking operation and a rigid contrasting portion for preventing incorrect positioning. This local quality differentiation allows the same component to provide both ease of operation and positioning accuracy.
Solution Approach 2:
The rigid contrasting portion of the spring-like member is positioned to interfere with the lamp flange before the flexible portion can allow incorrect locking. This preliminary anti-action prevents incorrect positioning from occurring in the first place, rather than merely correcting it after occurrence.
2Extent of automation
If the engine compartment is packed with more components, then driving safety and comfort are improved, but the available space for lamp replacement is reduced
Solution Approach 1:
The lamp holder device is designed to be self-indicating through the elastic contrasting means that visually or tactilely signal when the lamp is correctly positioned. This eliminates the need for external tools or complex alignment procedures, allowing technicians to quickly and easily replace lamps even in cramped spaces.
3Adaptability or versatility
If the lamp holder is mounted in the engine compartment, then the lighting device is integrated into the vehicle, but direct viewing of the lamp holder is difficult due to limited space
Solution Approach 1:
The elastic contrasting means may incorporate visual indicators such as color changes or contrasting markings that become visible when the lamp is correctly positioned. This allows the lamp holder status to be detected from a distance despite the confined engine compartment space.
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
Ensures the lamp is always locked in the correct position, preventing improper light distribution and facilitating easier assembly and replacement by providing a clear indication of incorrect positioning, even in limited visibility conditions.
Implementation Method 1
an elastically deformable spring-like member (15), having a first end hinged to first fastening means (17) of the collar (10)
Implementation Method 2
the spring-like member (15) is provided with at least one elastic contrasting means (30) adapted, when the flange (12) of the lamp (3) is not correctly housed in the seat (11), to interfere in use with the flange (12) of the lamp (3) and/or with the collar (10) so as to prevent the locking by coupling the spring-like member (15) against the collar (10)

AI summary
A lamp holder device (1) comprising a collar (10) carrying therein a housing seat (11) for a fixing flange (12) of a lamp (3) and either obtained in one piece with, or fixable to, a reflector (5) or a body (4) of a lighting device or light signaling device (2), and an elastically deformable spring-like member (15), having a first end (16) hinged to first fastening means (17) of the collar and a second end (18) provided with gripping means (19) adapted to allow a user to elastically deform the spring-like member (15) in use to lock it by coupling against the collar (10) so as to simultaneously lock in abutment the flange (12) of the lamp in the seat (11) of the collar onto a central portion (20) of the spring-like member; wherein the spring-like member (15) is provided with at least one elastic contrasting means (30) adapted, when the flange (12) of the lamp (3) is not correctly housed in the seat (11), to interfere in use with the flange (12) of the lamp and/or with the collar (10) so as to prevent the locking by coupling the spring-like member (15) against the collar (10).
