Decorative Lamp Assembly Using Grooved Light Panel Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional decorative lamps face issues of complex assembly, high labor costs, fragile structures, and safety hazards due to manual splicing and adhesive bonding of flexible light strips, which are prone to misalignment and detachment, leading to frequent contact failures and electrical safety risks.
Innovation Solution
A decorative lamp design featuring a base plate with a lamp groove, an integrated light panel, and a lampshade that mechanically interlock to constrain the light panel within the groove, eliminating the need for splicing and adhesive bonding through a two-step assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If segmented flexible light strips are manually cut and fixed to the base plate, then the lamp can be assembled, but the assembly process becomes complex and labor-intensive
Solution Approach 1:
The lamp groove is divided into multiple segments corresponding to different letter or pattern components. Each segment can independently accommodate a continuous flexible light strip, allowing parallel processing and assembly of multiple components simultaneously, thereby simplifying the overall assembly process while maintaining production efficiency
Solution Approach 2:
The flexible light strips are pre-cut to specific lengths and pre-configured to match the lamp groove segments before assembly. This preliminary preparation eliminates the need for on-site cutting and adjustment during assembly, significantly reducing labor intensity and improving production efficiency
2Ease of manufacture
If adhesive sealing strips are used to fix the light strips, then the assembly is simplified, but the structure becomes fragile and safety hazards increase
Solution Approach 1:
The adhesive bonding system is replaced with a mechanical constraint system. The lamp groove is designed with built-in constraint structures such as positioning ribs, clamping walls, or snap-fit mechanisms that mechanically secure the flexible light strips in place. This mechanical fixation method eliminates the fragility and aging issues of adhesive bonds while maintaining assembly simplicity, thereby improving structural stability and safety
Solution Approach 2:
The lamp groove incorporates localized constraint features at specific positions where the flexible light strips need securing. These local mechanical constraint structures provide targeted fixation without requiring continuous adhesive application, ensuring reliable structural stability while keeping the overall design simple and easy to manufacture
3Stability of the object's composition
If rigid segmented light strips are used, then the structure is stable, but adaptability to complex curves and small bending radii decreases
Solution Approach 1:
The patent employs flexible light strips with sufficient thinness and pliability to conform to complex curved paths and small bending radii of the lamp groove. These flexible strips maintain structural stability through internal support structures or tensioning mechanisms while adapting to various geometric configurations, thereby achieving both stability and adaptability

AI summary
The present disclosure discloses a decorative lamp. The decorative lamp comprises an integrally injection-molded base plate, a pre-formed light panel, and a strip-shaped lampshade. The base plate is provided with a lamp groove matching a target design, with the inner wall of the lamp groove constrained by a side wall. The light panel is integrated with light-emitting elements and precisely fits the contour of the lamp groove. During assembly, only placing the light panel into the lamp groove and pressing in the lampshade is required, eliminating the need for welding or adhesive bonding. This design achieves customized graphic display through structural synergy, significantly simplifying the assembly process, reducing production costs, and enhancing product reliability and light efficiency consistency, making it suitable for scenarios such as fan support signs and commercial signage.
