Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling panels with inorganic fiber boards face issues with securing strength when excessive loads are applied, leading to peeling off of attachment boards.
Innovation Solution
A ceiling panel design featuring a connection portion with a fastener that penetrates a cut portion on the back face of the panel body, providing enhanced securing strength by distributing load and using magnets for temporary fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an attachment board is fixed to the back face of the inorganic fiber board by an adhesive, then the attachment board can be easily installed, but the attachment board is easily peeled off when excessive load is applied
Solution Approach 1:
The connection member is divided into distinct functional parts: a base end side part that contacts the panel back face, an insertion part that penetrates the panel layer, and a fastener engagement structure. This segmentation allows each part to perform its specific function optimally - the base end side part provides load distribution, the insertion part ensures deep penetration for anchoring, and the fastener creates mechanical interlocking, collectively preventing peeling while maintaining ease of installation.
Solution Approach 2:
The connection member combines multiple materials with complementary properties: a rigid base end side part for structural support and load distribution, a penetrable insertion part that can be inserted into the panel layer, and a fastening mechanism. This composite structure integrates the advantages of different materials to achieve both easy installation and high securing strength under excessive loads.
2Strength
If a fastener penetrates the panel body from a cut portion on the back face, then the securing strength is improved, but the device complexity increases
Solution Approach 1:
The cut portion is pre-formed on the back face of the panel body at the end portion, creating a ready access point for the fastener. This preliminary action eliminates the need for complex drilling or cutting operations during installation, allowing the fastener to be simply inserted through the pre-prepared cut portion to achieve high securing strength without adding significant device complexity.
Solution Approach 2:
Instead of approaching the panel from the front face to create connections, the fastener approaches from the back face through the cut portion. This inverted approach allows the connection member to be secured from behind the panel, distributing loads more effectively across the panel thickness and achieving superior securing strength while maintaining a clean front surface 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 design significantly improves the securing strength of the connection member to the panel body, preventing peeling and ensuring stability under load, while also simplifying installation with magnetic temporary fixation.
Implementation Method 1
the connection member is fastened to the end portion by a fastener, the fastener being fastened to an insertion part inserted into a layer of the panel body from a cut portion opening on a back face of the end portion so as to penetrate a base end side part
