Outdoor Lamp Circuit Board Fixation via Elastic Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor lamp assemblies require screws and screw holes to fix the circuit board, leading to inefficiencies in assembly and increased production costs.
Innovation Solution
The outdoor lamp assembly structure uses an elastic abutment design with elastic pressing strips on the battery box to firmly position the circuit board without screws or screw holes, allowing for easy assembly and reduced production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and screw holes are used to fix the circuit board, then the circuit board is firmly positioned, but assembly time and labor costs increase
Solution Approach 1:
The patent removes screws and screw holes from the circuit board fixation system, extracting the fastening function from mechanical threaded connections and replacing it with an elastic pressing mechanism that achieves secure positioning without penetration or threading operations
Solution Approach 2:
The elastic pressing structure automatically secures the circuit board through elastic deformation and self-adjusting pressure, eliminating the need for manual screw tightening operations while maintaining reliable positioning through the inherent elastic properties of the material
2Reliability
If screws and screw holes are used to fix the circuit board, then the circuit board is firmly positioned, but production costs increase
Solution Approach 1:
The patent eliminates screws and screw holes from the design, removing the need for purchasing, inventory management, and processing of fastening components, thereby reducing material costs and simplifying the manufacturing bill of materials
Solution Approach 2:
The circuit board fixation function is merged into the battery box structure itself, where the elastic pressing strips are integrated as part of the battery box assembly, eliminating the need for separate fastening components and reducing overall part count
3Reliability
If multiple screw holes are formed on the base or lamp cover, then the circuit board can be securely fixed, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent removes screw holes from the base and lamp cover structures, eliminating the complexity of aligning and processing multiple holes while maintaining secure circuit board fixation through the elastic pressing mechanism
Solution Approach 2:
The fixation function is segmented into the elastic pressing strips on the battery box, which independently secure the circuit board without requiring coordinated holes or fasteners across multiple components, simplifying the overall assembly process

AI summary
An outdoor lamp assembly structure includes a base, a lamp cover, and a circuit board and a battery box installed on the base. The center of the circuit board is provided with an opening, the battery box is arranged in the opening, and a multiple of elastic pressing strips has a height higher than the top plate of the circuit board and extends obliquely outward from the top plate. During assembly, the lamp cover presses downwardly against the battery box to drive the plurality of elastic pressing strips to press downwardly against the circuit board to complete the positioning of the circuit board, so as to save the assembling time and cost.
