Solution Overview

Problem

Underground lamps are prone to breakage due to pressure from being treaded on, as their panels are flush with the ground and lack adequate protection.

Innovation Solution

The design incorporates a seal ring and a reflection cup with a support ring made of rubber, which together form a buffer space between the panel and the lamp body, reducing the risk of damage from pressure. Additionally, a rotation shaft assembly allows for adjustable light direction, and a waterproof adjustment hole member ensures durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the panel is made flush with the ground to achieve space saving and good light emission effect, then the aesthetic appearance and light emission are improved, but the panel becomes liable to pressure from being treaded and has a high risk of breakage

Engineering Contradiction:
Improvelight emission effectVSAvoidpanel breakage resistance
Core Design Contradiction:
Illumination intensityVSStrength

Solution Approach 1:

The patent applies beforehand cushioning by introducing a buffer space between the panel and the lamp body, filled with rubber material. This buffer space is created beforehand to absorb and mitigate pressure from external forces (such as being treaded), preventing the panel from breaking while maintaining its flush mounting with the ground for aesthetic and lighting purposes.

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

2Volume of moving object

If the panel is made flush with the ground to achieve space saving, then the space utilization is improved, but the panel becomes vulnerable to external pressure and damage

Engineering Contradiction:
Improvespace savingVSAvoidpanel durability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The buffer space filled with rubber material serves as a pre-established protective mechanism that absorbs external pressure before it can reach and damage the panel, thereby maintaining both the space-saving flush mounting and the durability of the panel.

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

Solution Approach 2:

The rubber material used in the buffer space acts as a flexible element that can deform under pressure and then return to its original shape, providing continuous protection to the panel while allowing the panel to remain flush with the ground surface.

Inventive Principle:
Principle #30Flexible shells and thin films

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

The buffer space significantly reduces the risk of panel damage from pressure, while the adjustable light direction and waterproof features enhance the lamp's functionality and durability.

Implementation Method 1

the support ring is made of a rubber material, the installation port has an installation port inner edge, and the installation port inner edge has an abutment step circumferentially surrounded by the installation port; the panel covers the abutment ring and is fixed to the lamp body, the seal ring is disposed between the abutment ring and the panel, the seal ring is pressed by the panel and the abutment ring in cooperation, the support ring is disposed between the abutment step and the panel, and the support ring is pressed by the panel and the abutment step in cooperation
