Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sign assembly technologies face challenges in simplifying the production and mounting of lightweight signs, particularly those made from materials like cellular plastic, as they often require complex adhesives and struggle with warpage and moisture ingress.
Innovation Solution
A sign assembly design featuring a bracket that extends over the frame, connecting to its ends and clamping the frame, allowing for easy mounting and suspension with options like snap locks, bolts, or magnetic connections, while using lightweight materials like channel plastic and thin sheet metals for the panels and frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight materials like cellular plastic and channel plastic are used for sign production, then the weight and complexity of the sign is reduced, but the sign becomes susceptible to warpage and moisture ingress
Solution Approach 1:
The patent employs a frame structure that acts as a rigid shell enclosing the lightweight sign panels. The frame runs about the peripheries of the front and rear panels, providing structural support that prevents warpage while maintaining the lightweight characteristics of the core sign materials.
Solution Approach 2:
The sign assembly combines multiple materials with complementary properties: lightweight cellular plastic and channel plastic for the panels, metal or rigid plastic for the frame, and sealing materials at the joints. This composite construction achieves both light weight and resistance to environmental factors.
2Reliability
If traditional sign mounting methods are used, then the sign can be securely fixed to the wall, but the production and mounting process becomes complex and time-consuming
Solution Approach 1:
The patent integrates the mounting function directly into the frame structure by incorporating brackets that extend from the rear panel and bend over the frame. This merging of structural and mounting functions allows the sign to be both supported and secured in a single operation, eliminating separate mounting steps.
Solution Approach 2:
The frame with integrated brackets is designed to be self-mounting. The brackets extend from the rear panel, bend over the frame, and connect to the wall, allowing the sign assembly to perform its own mounting function without requiring additional external mounting components or complex assembly procedures.
3Strength
If the frame ends are joined with complex connections to ensure structural integrity, then the joint strength is improved, but the manufacturing complexity and time increase
Solution Approach 1:
The patent replaces complex mechanical joint systems with simpler connection methods. The frame ends are joined using straightforward connections such as snap locks, bolts, rivets, or adhesive joints, which provide sufficient structural integrity while dramatically reducing manufacturing complexity and assembly time compared to traditional mechanical joint systems.

AI summary
A sign is disclosed, arranged to be mounted hanging from a wall, the sign comprising a rear panel (5) and a front panel (3) the peripheries of which are surrounded by a frame (6) in the form of an elongate, unitary or assembled member that runs sweeping about the sign while forming at least one joint ( 14) at which two ends (12, 13) of the frame meet, said sign being associated with a sign suspension means (16) comprising a bracket (17; 18) which is extended to reach folded over the frame from the rear panel upon mounting of the sign. The bracket (17; 18) is arranged for coupling to each of the meeting ends (12, 13) of the frame in order to fixate the ends of the frame under the bracket while simultaneously clamping the frame (6) about the sign (1).
