Solution Overview

Problem

Conventional lighting device attachment methods to curved surfaces, such as vehicle door linings, require screw members, increasing the number of assembly steps and potentially leading to instability due to mismatched shapes.

Innovation Solution

An attachment structure featuring a pedestal with a flat plate-shaped base and an attachment member that includes a supporting wall section, claw member, and projection, allowing stable fixation without screws by restricting vertical and lateral movement, and utilizing a die-cut hole for easy formation of the claw member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screw members are used to attach the lighting device to the curved surface, then the attachment stability is improved, but the number of assembly steps increases

Engineering Contradiction:
Improveattachment stabilityVSAvoidnumber of assembly steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the screw members from the attachment system. The attachment member is designed with a claw member that engages directly with the lighting device housing, removing the need for separate fastening components and simplifying the assembly process while maintaining stable attachment to the curved surface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The attachment member acts as an intermediary between the curved surface and the lighting device. It includes a base section that contacts the curved surface and an attachment member with a claw member that secures the lighting device, providing a stable connection without requiring direct screw fastening to the housing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the lighting device housing shape does not correspond to the curved surface, then the device can be designed with standard shapes, but the attachment stability deteriorates

Engineering Contradiction:
Improvehousing shape standardizationVSAvoidattachment stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The attachment system is segmented into distinct functional components: the base section that adapts to the curved surface geometry, and the attachment member with the claw member that secures the standard-shaped lighting device housing. This segmentation allows the housing to maintain standard shapes while the attachment interface adapts to the curved surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base section is designed with local quality adaptation to the curved surface, while the attachment member maintains a standardized interface for the lighting device housing. The claw member provides localized engagement with the housing, ensuring stable attachment without requiring the entire housing to conform to the curved surface geometry.

Inventive Principle:
Principle #3Local quality

3Reliability

If claw member restricts movement away from base section, then the attachment stability is improved, but the device complexity increases

Engineering Contradiction:
Improveattachment stabilityVSAvoidattachment member structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment member merges multiple functions into a single integrated component: the base section provides structural support and contacts the curved surface, while the claw member integrated into the attachment member provides mechanical engagement with the lighting device housing. This merging reduces overall complexity compared to separate fastening components.

Inventive Principle:
Principle #5Merging (Combining)
