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
Engineering 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
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.
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.
2Manufacturing precision
If a fixed angle mounting is used, then the manufacturing precision is improved, but the adaptability to various site conditions deteriorates
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.
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.
3Strength
If bolts are used for fastening, then the joining strength is improved, but the reliability under vibrations deteriorates due to bolt loosening
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.
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
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.

Function Achieved in This Case
Ensures stable angle adjustment and maintenance even under vibrations, enabling easy and convenient irradiation angle adjustment and full 360-degree rotation, thus adapting to various site conditions and meeting consumer needs.
Implementation Method 1
apples a shock absorbing assembly to a body, thus protecting an angle adjusting means from vibrations, and which prevents a bolt from being loosened from an internal threaded portion, as if a spring washer were applied, due to inherent elasticity of a shock absorbing member
