Solution Overview

Problem

Existing lighting apparatuses for vehicles driven on rough roads or construction sites lack stability in maintaining adjusted angles due to vibrations and shocks, and existing angle adjusting technologies are not suitable for environments with significant mechanical stress.

Innovation Solution

A lighting apparatus with a shock-absorbing assembly and a mounting system that includes a fastening plate with a rotary hole and an end plate with an annular guide protrusion, allowing for 360-degree rotation and secure angle adjustment, preventing bolt loosening through inherent elasticity, and enhancing coupling ability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple mounting structure is used, then the device complexity is reduced, but the stability under vibrations and shocks deteriorates

Engineering Contradiction:
Improvemounting structure complexityVSAvoidangle stability under vibrations
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies beforehand cushioning by incorporating a shock-absorbing member between the mounting bracket and the lighting apparatus body. This member is designed to absorb vibrations and shocks before they can affect the angle adjustment stability, thereby maintaining reliable angle positioning without requiring an overly complex mounting structure.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The mounting structure is segmented into distinct functional components: a mounting bracket for attachment, a shock-absorbing member for vibration isolation, and an angle adjusting mechanism for positioning. This segmentation allows each component to perform its specific function efficiently, achieving stability without unnecessary complexity.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If a fixed angle mounting is used, then the manufacturing precision is improved, but the adaptability to various site conditions deteriorates

Engineering Contradiction:
Improvepre-adjusted angle precisionVSAvoidadaptability to site conditions
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by providing an angle adjusting mechanism that allows the lighting apparatus to be rotated and positioned at different angles after manufacturing. The mechanism includes a rotary hole, guide protrusion, and locking features that enable dynamic adjustment while maintaining precise positioning at the selected angle, thus combining manufacturing precision with field adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables parameter changes by allowing the installation angle of the lighting apparatus to be modified after manufacturing. The angle adjusting mechanism permits changing the orientation parameter from a fixed pre-set value to any desired angle within the mechanical limits, accommodating various site conditions while maintaining precise angular positioning.

Inventive Principle:
Principle #35Parameter changes

3Strength

If bolts are used for fastening, then the joining strength is improved, but the reliability under vibrations deteriorates due to bolt loosening

Engineering Contradiction:
Improvefastening strengthVSAvoidresistance to bolt loosening
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The patent applies the intermediary principle by introducing a shock-absorbing member as a mediator between the bolted connection and the vibrations. This member absorbs vibrational energy, preventing it from transmitting to the bolts and causing loosening, thereby maintaining both fastening strength and reliability under vibrational conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If angle adjustment is made after installation, then the ease of operation is improved, but the stability of adjusted state under shocks deteriorates

Engineering Contradiction:
Improvepost-installation angle adjustmentVSAvoidadjusted angle stability under shocks
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies beforehand cushioning by placing a shock-absorbing member at the interface between the mounting bracket and the body. This member protects the post-installation angle adjustment from being disrupted by vibrations and shocks, maintaining the stability of the adjusted state while preserving the ease of operation for field adjustment.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
