Display Device Front Frame Splicing Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoisting display devices face issues with splicing misalignment and low precision due to machining errors in the triangular fixed mount, leading to poor splicing efficiency and precision.
Innovation Solution
The display device incorporates a first and second front frame with positioning bosses and studs that align and lock, ensuring accurate splicing and positioning by plugging the positioning stud into the boss, which then allows for secure fastening to a triangular fixed mount, enhancing precision and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a triangular fixed mount is used to connect two display screens, then the display structure can be assembled, but splicing misalignment and low precision occur due to machining errors
Solution Approach 1:
The positioning structure is divided into separate components: a positioning boss on the first front frame and a positioning stud on the second front frame. This segmentation allows each component to be manufactured independently with standard tolerances, while their assembly provides precise positioning without requiring high-precision machining of the entire triangular fixed mount.
Solution Approach 2:
The positioning boss and positioning stud act as intermediary elements between the two display screens. These intermediaries transfer and ensure precise positioning relationships, allowing the main triangular fixed mount to be manufactured with常规 tolerances while still achieving high splicing precision through the intermediary positioning features.
2Manufacturing precision
If positioning bosses and studs are added to the front frames, then splicing precision is improved, but device complexity increases
Solution Approach 1:
The positioning bosses and studs are merged directly into the front frame structures of the display screens. By integrating these positioning features into the existing front frames rather than adding separate positioning components, the solution achieves precise positioning while minimizing additional device complexity.
Solution Approach 2:
The front frames serve multiple functions: they provide structural support for the display screens, incorporate the positioning bosses/studs for precise alignment, and interface with the triangular fixed mount. This multi-functionality reduces the need for separate positioning components, thereby limiting the increase in device complexity.
