Base Plate Escutcheon Fastener Assembly Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing combination structures of base plates and escutcheons face issues with proper fitting and disassembly, as the escutcheon often slips or is difficult to remove due to the use of screws, complicating the assembly process and affecting the aesthetic appeal.
Innovation Solution
A combination structure featuring a base plate with a ring-like wall and a fastener having a fastening and fixing portion, where the escutcheon is restrained by the fastening portion to prevent disengagement, allowing for stable assembly and easy disassembly by exposing the fastening portion through an opening in the escutcheon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw is utilized to fix base plate and escutcheon, then the escutcheon is securely fixed to the base plate, but the escutcheon disassembling steps become complicated and inconvenient
Solution Approach 1:
The fastener is divided into three distinct portions: a fastening portion that engages with the escutcheon, a flexible portion that provides mechanical advantage, and a fixing portion that anchors to the base plate. This segmentation allows the fastener to function as both a secure anchor and a tool for easy removal, resolving the contradiction between secure fixing and easy disassembly.
Solution Approach 2:
The flexible portion acts as an intermediary element between the fastening portion and the fixing portion. This intermediate section enables the fastener to be pushed through the escutcheon opening for installation while maintaining the structural integrity needed for secure fixation, and simultaneously allows for easy retrieval during disassembly.
2Reliability
If a screw is utilized to fix base plate and escutcheon, then the escutcheon is securely fixed to the base plate, but the aesthetic appeal of the combination structure is affected
Solution Approach 1:
The fastening mechanism is extracted from the visible surface of the escutcheon and relocated to the reverse side, where it engages with the base plate through the opening. This extraction eliminates the visual impact of traditional screw heads on the aesthetic surface while maintaining secure fixation through the fastener's engagement with both the escutcheon and base plate.
3Reliability
If the escutcheon is restrained by the fastening portion of the fastener, then assembly reliability is enhanced, but the disengagement process requires exposing the fastening portion through an opening
Solution Approach 1:
An opening is preliminarily formed in the escutcheon at the location where the fastening portion will be positioned. This preliminary action enables the fastening portion to be easily accessed and manipulated during both installation and disassembly, reducing the complexity of the disengagement process while maintaining secure restraint during normal operation.

AI summary
A combination structure of base plate and escutcheon comprises a base plate, a fastener and an escutcheon. The base plate has a plate and a ring-like wall surrounding the plate, and the fastener has a fastening portion, a fixing portion and a flexible portion connecting the fastening portion and the fixing portion. The fixing portion is installed on the ring-like wall and the base plate is covered with the escutcheon. The escutcheon has a sidewall, an opening and a limited-portion. The opening is formed on the sidewall and exposes the fastening portion of the fastener. The limited-portion of the escutcheon is restrained by the fastening portion of the fastener to prevent the escutcheon disengaging from the base plate.
