Weatherboard Holder With Rotational Bracket And Hook Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for attaching weatherboards to window or door frames require additional preparatory operations like gluing or screwing, which complicates the assembly process and restricts versatility due to the need for different weatherboard profiles and frame profiles.
Innovation Solution
A holder with multiple connecting elements, including a circular and hook-shaped or pin-shaped design, utilizes existing water slots in the profile frame for anchoring, allowing for rotational adjustment and rigid connection without the need for separate anchoring holes, enabling connection of various weatherboards to different frame profiles using existing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If weatherstrips are manufactured as separate attachable components, then manufacturing cost and handling ease are improved, but assembly complexity increases due to additional connection operations
Solution Approach 1:
The bracket is designed to combine multiple functions into a single component: it provides mechanical connection between the weatherstrip and frame, enables rotational adjustment for positioning, and utilizes existing water slots for anchoring without requiring separate gluing or screwing operations. This merging reduces the number of separate components and assembly steps.
Solution Approach 2:
The bracket is designed as a universal connecting component that can attach various weatherstrip profiles to different frame profiles through its dual connecting elements. It performs multiple functions simultaneously: rigid connection, rotational adjustment, and anchoring via existing frame features, eliminating the need for profile-specific connection solutions.
2Strength
If additional preparatory operations like gluing or screwing are used for anchoring, then connection strength is improved, but assembly time and process complexity increase
Solution Approach 1:
The bracket is pre-designed with connecting elements that utilize existing water slots in the frame profile for anchoring. The water slots are already present in the frame during manufacturing, eliminating the need for additional preparatory operations like drilling holes or surface preparation during assembly. The bracket simply needs to be snapped or clipped into these pre-existing features.
Solution Approach 2:
The existing water slots in the frame profile serve a dual purpose: their original drainage function and as anchoring points for the bracket. The frame structure itself provides the anchoring mechanism without requiring additional components or operations, making the system self-sufficient and reducing assembly steps.
3Adaptability or versatility
If different weatherstrip profiles are manufactured for different frame profiles, then adaptability is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The bracket serves as a universal adapter that enables a single weatherstrip profile to be connected to multiple different frame profiles. The dual connecting elements (one on the weatherstrip side, one on the frame side) are designed to accommodate various profile types, eliminating the need to manufacture different weatherstrip profiles for different frames.
Solution Approach 2:
The bracket acts as an intermediary component between the weatherstrip and the frame profile. Instead of modifying the weatherstrip profile itself to adapt to different frames, the bracket mediates the connection, providing interface compatibility between standard weatherstrip profiles and various frame types.
4Reliability
If anchoring holes are created in the frame profile, then anchoring reliability is improved, but drainage function may be blocked and structural integrity is reduced
Solution Approach 1:
The existing water slots in the frame profile serve dual functions: their original purpose of draining condensation and water, and as anchoring points for the bracket's connecting elements. This eliminates the need to create separate anchoring holes that would compromise drainage or structural integrity.
Solution Approach 2:
The frame profile's existing water slots automatically serve as anchoring features for the bracket. The frame structure provides its own anchoring mechanism without requiring additional modifications, maintaining both drainage functionality and structural integrity while providing reliable anchoring.

AI summary
A bracket 10 for connecting a weatherstrip 11 to a profile frame 12 has two oppositely oriented connecting elements 20, 30, wherein the first connecting element 20 allows rotation about an axis when connected, and the second connecting element 30 only enables a rigid connection. The first connecting element 20 has a substantially circular cross-section, while the second connecting element 30 is substantially hook-shaped or tenon-shaped. The bracket is positioned between the profile frame and the weatherstrip and is anchored on the side of the profile frame in an opening 13 provided therein by the second connecting element 30.
