Removable Sign Panel Assembly with Pivot Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing yard signs with plastic frames require disassembly to change out sign panels, which is inconvenient and time-consuming.
Innovation Solution
A sign assembly design featuring spaced upright and lateral frame members with downward and upward facing slots allows for easy removal and replacement of sign panels by shifting and pivoting them within the frame, enabling panel changeout without full disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If plastic frame signs are used for higher end purposes, then aesthetic appeal is improved, but the complexity of changing sign panels increases
Solution Approach 1:
The sign frame is divided into separate components: the plastic frame structure and the sign panel. The frame includes lateral members with slots that can independently receive and release panels, allowing the panel to be segmented from the frame for easy replacement while maintaining the integrity and aesthetic appeal of the plastic frame structure.
Solution Approach 2:
The sign panel is extracted as a removable component from the plastic frame. The lateral members are designed with slots that can accommodate the panel edges, allowing the panel to be taken out and replaced without disassembling the entire frame structure, thus maintaining aesthetic appeal while enabling easy panel changes.
2Strength
If traditional sign frame designs are used, then structural integrity is maintained, but the time required to change sign panels increases
Solution Approach 1:
The sign panel is designed to be dynamically removable and replaceable within the plastic frame. The lateral members include slots that allow the panel to be inserted and secured in a simple motion, and removed by reversing the action, enabling quick panel changes without compromising the structural integrity of the frame.
Solution Approach 2:
The lateral members are pre-configured with slots and the panel is pre-formed with edges that fit these slots. This preliminary configuration allows the panel to be quickly installed by simply aligning and inserting it into the slots, eliminating the need for complex assembly steps and reducing panel changeout time while maintaining structural integrity.
3Adaptability or versatility
If sign panels are made removable, then versatility is improved, but the complexity of the frame structure increases
Solution Approach 1:
The plastic frame with its lateral members and slots is designed as a universal structure that can accommodate multiple different sign panels. The slots in the lateral members provide a standardized interface that can receive various panel types, enabling the frame to serve multiple functions and support different signage needs without requiring frame modification or disassembly.

AI summary
A sign frame includes spaced apart first and second upright frame members, a first lateral frame member extending between the first upright frame member and the second upright frame member, and a second lateral frame member extending between the first upright frame member and the second upright frame member, the second lateral frame member spaced vertically below the first lateral frame member to define a sign panel receiving space therebetween. The first lateral frame member includes a lower side with a downward facing panel receiving slot. The second lateral frame member includes an upper side with an upward facing panel receiving slot. The downwardly facing panel receiving slot is sized and configured for permitting an upper edge section of a sign panel to be shifted upward and pivotably moved within the downwardly facing panel receiving slot.
