Reinforced Light Engine Module for Tool-Free Lamp Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement of a light engine in a lamp requires specialized tools and knowledge, leading to potential damage and high costs due to the lack of mechanical stability during installation by end users.
Innovation Solution
A light engine module with a reinforcement or bracket is provided to stabilize the second light engine, allowing for easy replacement without additional tools, maintaining optical performance and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light engine is designed for direct installation in the lamp during manufacturing, then the manufacturing process is simplified and BOM is reduced, but the light engine lacks mechanical stability during end-user replacement leading to potential damage
Solution Approach 1:
The solution segments the replacement system into two parts: the light engine itself (designed for simple manufacturing without reinforcement) and a separate reinforcement element (provided with the replacement light engine). This allows the original lamp manufacturing to remain simple while enabling stable user-side replacement.
Solution Approach 2:
The reinforcement element acts as an intermediary component that mediates between the light engine and the lamp housing. It provides the necessary mechanical stability during user replacement without requiring the lamp manufacturing process to be more complex.
2Ease of manufacture
If the light engine is provided without reinforcement for cost reduction, then the BOM is reduced, but the end user lacks the tools and knowledge to install it safely
Solution Approach 1:
The reinforcement element is designed to be self-explanatory and self-installing. It comes with the replacement light engine in a ready-to-use state, allowing end users to perform the installation themselves without requiring specialized tools or technical knowledge.
Solution Approach 2:
The reinforcement element is prepared in advance as part of the replacement kit, with all necessary components pre-assembled or pre-configured. This preliminary preparation eliminates the need for users to perform complex assembly steps or use specialized tools during installation.
3Volume of moving object
If the light engine is made compact for space efficiency, then the lamp design is optimized, but the mechanical stability during handling is reduced increasing damage risk
Solution Approach 1:
The solution separates the compact light engine from the reinforcement structure. The light engine maintains its compact, space-efficient design while the separately provided reinforcement element adds the necessary mechanical strength and stability during handling and installation.

AI summary
A method for replacing a light source of a lamp is provided. The method includes providing a lamp in which a first light engine is installed, providing a light engine module with a second light engine, and removing the first light engine from the lamp. The method further includes installing the light engine module in the lamp to replace the first light engine. The light engine module includes a reinforcement for mechanically stabilizing the second light engine. The installation of the light engine module includes installing both the second light engine and reinforcement in the lamp. In addition, a first light engine, a light engine module and a lamp are also provided.
