Modesty Panel Base Member for Uneven Wall Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modesty panels face challenges in being securely attached to uneven building surfaces and may become unstable when a water draining member is present between upper and lower external wall panels, particularly due to their heavy weight and the need for decorative coatings.
Innovation Solution
A modesty panel design featuring a base member with upper and lower attaching portions and corresponding engaging ridges on the panel, allowing for stable engagement and screw fixation, even on uneven surfaces, with optional features like dented grooves and protruded ridges for improved attachment and tool accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If fiber reinforced cement siding type modesty panel is used, then dignity and appearance are improved, but weight increases and workability deteriorates
Solution Approach 1:
The modesty panel is divided into two separate components: a base member that attaches to the wall and a panel main body that attaches to the base member. This segmentation allows each component to be optimized independently - the base member can be lightweight while the panel main body provides the desired appearance, resolving the contradiction between weight and appearance.
Solution Approach 2:
The base member acts as an intermediary component between the wall and the panel main body. It provides the heavy-duty attachment function to the wall while the panel main body provides the aesthetic function, separating the structural and cosmetic roles to achieve both light weight and good appearance.
2Stability of the object's composition
If base member with large flat fixing surface is used, then fixing stability is improved, but adaptability to uneven surfaces deteriorates
Solution Approach 1:
The fixing function is segmented from the panel main body and concentrated in the base member, which is specifically designed with engaging ridges and stepped portions. This allows the base member to provide stable fixing through mechanical engagement while the overall structure remains adaptable to surface variations.
Solution Approach 2:
The base member features localized engaging ridges and stepped portions at specific locations rather than a uniform flat surface. This local quality approach provides stable fixing points while allowing other areas to accommodate surface unevenness, resolving the contradiction between fixing stability and adaptability.
3Ease of operation
If engaging ridges and stepped portions are used, then ease of operation is improved, but reliability of attachment deteriorates
Solution Approach 1:
The engaging ridges on the panel main body are designed to elastically deform during attachment and then maintain a secure locked position. This dynamic behavior allows for easy insertion while ensuring reliable attachment, as the elastic deformation enables the ridges to snap into the stepped portions and hold firmly.
Solution Approach 2:
The base member and panel main body are made of resin materials that combine ease of molding for complex engaging structures with sufficient strength for reliable attachment. The composite structure of engaging ridges, stepped portions, and screw holes provides both operational ease and attachment reliability.

AI summary
The present invention provides a modesty panel capable of being stably attached to a fixing surface of a building side regardless of the unevenness of the fixing surface, and an external wall construction structure in which the modesty panel is attached. In the external wall construction structure, a base member 10 provided with an upper attaching portion 12 and a lower attaching portion 13 is fixed to the building external wall surface 2. The base member 10 has first and second engaging stepped portions 16 and 17. To this base member 10, a modesty panel main body 30, provided with first and second engaging ridges 32 and 33, is outwardly engaged. In a superimposed region S formed by the engagement, a fixing screw 4 is screwed to integrally and firmly fix the modesty panel main body 30 and the base member 10.
