Solution Overview

Problem

The existing LED lighting arrangements face issues with soldered connections leading to deformation, increased storage and costs, mechanical warping, and operational reliability due to thermal and mechanical loads, as well as complex and error-prone assembly processes.

Innovation Solution

A lighting arrangement with a holder featuring an electrical coupling element that allows for physical contact with the lighting module, enabling easy electrical coupling and assembly, and incorporating a resilient design to decouple mechanical loads, ensuring reliable operation and simplified assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If soldered connections are used to connect wiring to the lighting module, then electrical coupling is achieved, but the soldering point protrudes causing the plastic holder to deform and not lie flat on the circuit board

Engineering Contradiction:
Improveelectrical couplingVSAvoidflatness of plastic holder
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent extracts the soldering operation entirely from the assembly process. Instead of soldering wiring to the circuit board, the invention uses pre-attached wire leads that are simply inserted through the circuit board and held in place by the holder body, eliminating the protruding solder points that cause deformation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of attaching wiring to the circuit board first (traditional approach), the invention inverts the sequence by having the holder body itself serve as the mounting structure that receives both the circuit board and the wire leads simultaneously, preventing deformation during assembly.

Inventive Principle:
Principle #13The other way round (Inversion)

2Manufacturing precision

If the plastic holder is screwed to the circuit board to ensure alignment, then initial alignment is achieved, but thermal influences cause degeneration and mechanical warping during operation

Engineering Contradiction:
ImprovealignmentVSAvoidstructural stability
Core Design Contradiction:
Manufacturing precisionVSStability of the object's composition

Solution Approach 1:

The patent replaces rigid screw connections with a dynamic spring mechanism that allows for thermal expansion and contraction. The spring element maintains constant contact pressure between the holder and circuit board while accommodating dimensional changes due to temperature variations, preventing warping and fatigue.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes the mechanical properties of the connection from rigid (screws) to elastic (spring element). This parameter change allows the connection to adapt to thermal influences and mechanical loads, maintaining alignment while preventing structural degradation.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If spring frames are used to contain mechanical loads, then some protection is provided, but the frame body bends and distorts during assembly and operation

Engineering Contradiction:
Improveprotection from mechanical loadsVSAvoidframe body distortion
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The patent introduces a spring element as an intermediary between the holder body and the circuit board. This spring mediator absorbs mechanical loads and vibrations while maintaining proper alignment, preventing the frame body from bending or distorting under stress.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If separate modules with soldered connection lines are created for each type of lamp, then specific lighting requirements are met, but production costs increase and assembly becomes complex

Engineering Contradiction:
Improvelighting module specificityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal holder design that can accommodate different types of lighting modules without requiring separate specialized holders for each lamp type. The standardized wire lead insertion mechanism and spring element work with various circuit board configurations, simplifying production and assembly.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention separates the holder body from the electrical connection function. The holder body serves as a universal mechanical support, while the wire leads provide the electrical connection, allowing different lighting modules to be used with the same holder structure.

Inventive Principle:
Principle #1Segmentation
