Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting devices with vertical cylindrical designs face challenges in assembly due to differing installation and light-emitting directions, leading to increased manufacturing costs and light leakage issues.
Innovation Solution
A light-emitting device design featuring a base, shell, circuit board, and two covering bodies with a through hole, where the light-emitting element is perpendicular to the installation direction, and the covering bodies form a space with an opening corresponding to the hole, reducing light leakage and assembly complexity by focusing the light beam and providing a separation distance to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the installation direction of the light-emitting element is consistent with the light-emitting direction, then the assembly process is simple, but light leakage from the mask occurs and luminous efficiency is reduced
Solution Approach 1:
The patent changes the installation direction of the light-emitting element to be perpendicular to the light-emitting direction, transitioning from a one-dimensional alignment to a two-dimensional spatial arrangement. This dimensional change allows the light-emitting element to be installed on the circuit board without compromising luminous efficiency, while the mask is positioned to focus light through a through-hole, resolving the contradiction between assembly simplicity and light leakage prevention.
2Loss of energy
If the light-emitting element is positioned close to the mask to focus light, then luminous efficiency improves, but collision between the shell and light-emitting element occurs during assembly
Solution Approach 1:
The patent positions the light-emitting element perpendicular to the light-emitting direction, creating separation in the installation direction while maintaining optical focus through the mask's through-hole. This spatial reconfiguration in another dimension allows the light-emitting element to be close enough for effective light focusing while preventing collision with the shell during assembly.
Solution Approach 2:
The mask with its through-hole acts as an intermediary structure that focuses light from the light-emitting element while allowing spatial separation between the element and the shell. The through-hole configuration enables light concentration without requiring direct contact or close proximity that would cause assembly conflicts.
3Ease of operation
If the light-emitting element is positioned far from the mask to avoid collision, then assembly becomes easier, but light focusing capability is reduced
Solution Approach 1:
By changing the installation direction to be perpendicular to the light-emitting direction, the patent enables the light-emitting element to be positioned at an optimal distance for assembly ease while the mask's through-hole geometry maintains effective light focusing. The spatial reconfiguration allows separation in the installation dimension while preserving optical coupling.
