Ceiling Anchor Bolt Assembly for Vibration-Resistant Panel Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling finishing panel fixing devices face challenges such as difficulty in separating panels for repair, aesthetically unpleasing exposed screw bolts, cumbersome installation processes, risk of anchor bolts falling due to vibration, and increased installation time.
Innovation Solution
An improved anchor bolt assembly with a pointed protrusion on the anchor body, a Y-shaped incised part on the anchor shell, a double screw thread, and a reinforcing pipe to prevent bending, along with a hanger with cushioning material to absorb vibrations, and a magnet to conceal screw bolts, facilitating tool-free installation and enhanced aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional strong anchor with conical wedge and sleeve pipe is used, then the anchor can be inserted into the ceiling slab, but the anchor may fall out by vibration and the ceiling may collapse
Solution Approach 1:
The anchor body is segmented into multiple wedge-shaped expansion pieces that can independently expand and lock into the ceiling slab, providing distributed fixation points that resist vibration-induced loosening
Solution Approach 2:
The anchor body is pre-assembled with the expansion pieces in a compact state before insertion, allowing for precise positioning and ensuring that the expansion mechanism is ready to engage immediately upon insertion without requiring additional assembly steps
2Ease of manufacture
If a full-threaded bolt is used, then the anchor can be assembled completely, but the bolt may be bent by vibration or wind pressure
Solution Approach 1:
The bolt is segmented into a full-threaded portion and a smooth portion, where the full-threaded part provides assembly capability while the smooth portion acts as a flexible element that can bend without breaking under vibration or wind pressure
Solution Approach 2:
The bolt geometry is changed along its length, transitioning from a full-threaded section to a smooth section, allowing different portions to serve different functions: threading for assembly and smooth surface for flexibility and vibration resistance
3Reliability
If a conventional installation process is used, then the anchor can be fixed to the ceiling slab, but the installation time is increased due to tightening or loosening action
Solution Approach 1:
The anchor body automatically expands and locks into the ceiling slab through its wedge-shaped expansion pieces, eliminating the need for separate tightening or loosening actions and significantly reducing installation time
Solution Approach 2:
The complex tightening and loosening mechanisms are extracted from the anchor system, replacing them with a simple insertion-based expansion mechanism that achieves fixation without additional operational steps
4Ease of manufacture
If screw bolts are exposed on the finishing panel, then the panel can be fixed to the panel fixing bar, but the exposed screw bolt is not good aesthetically
Solution Approach 1:
A decorative cap or cover is introduced as an intermediary element that conceals the screw bolt while allowing the panel to remain securely fixed to the panel fixing bar, thus resolving the conflict between fixation functionality and aesthetic appearance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables easy and secure fixation of anchor bolts to ceilings without tools, reduces installation time, prevents anchor body spinning and bending, and improves the aesthetic appearance of finished ceilings by concealing screw bolts.
