Roof Supporting Clasp Structure for Transverse Load Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supporting clasps for roof-installed objects lack sufficient bending rigidity, leading to inadequate support when loads act perpendicular to the securing member, particularly in transverse directions, and can result in incomplete securing due to uneven distribution of loads and manufacturing gaps.
Innovation Solution
A supporting clasp with a rectangular bottom portion, plate-form installing pieces, and plate-form holding pieces that extend perpendicularly and are coupled in a continuous manner, forming a curved outer circumference, which prevents bending and enhances load resistance by distributing loads evenly across both holding pieces, and includes excretory holes to prevent water accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If holding pieces are erected by simply folding a plate material linearly, then the structure is simple and easy to manufacture, but the bending rigidity is poor and the holding pieces bend under load
Solution Approach 1:
The holding pieces are designed with curved surfaces instead of linear folds, specifically with a first curved surface on the inner side and a second curved surface on the outer side. These curved surfaces provide structural reinforcement that prevents bending under load while maintaining ease of manufacture through forming processes.
2Device complexity
If only one holding piece supports the load in the transverse direction, then the structure is simple, but the securing member cannot be sufficiently supported under heavy loads and weather conditions
Solution Approach 1:
The supporting clasp is divided into multiple functional segments: a bottom portion for securing to the roof, installing pieces for supporting the securing member in the inclination direction, and holding pieces for supporting the securing member in the transverse direction. This segmentation allows each piece to specialize in specific load directions while working together for comprehensive support.
Solution Approach 2:
The design adds dimensional complexity by creating holding pieces that extend in the transverse direction perpendicular to the inclination direction. This multi-directional support structure distributes loads across both holding pieces, preventing any single piece from bearing excessive weight under heavy loads or severe weather conditions.
3Ease of manufacture
If spaces are formed between installing pieces and holding pieces for manufacturing reasons, then the manufacturing process is simple, but the holding pieces fall to the inner side and the securing member cannot be supported at an accurate position
Solution Approach 1:
The curved surfaces on the holding pieces create a self-aligning geometry that eliminates gaps between components. The first curved surface on the inner side and the second curved surface on the outer side work together to position the holding pieces precisely relative to the installing pieces, preventing inward falling and ensuring accurate positioning of the securing member.

AI summary
A supporting clasp which supports a securing member for securing a roof-installed object to be installed on a roof includes a bottom portion having a substantially rectangular shape which is secured onto a roof material through a base member, plate-form installing pieces which extend to the upper side from two sides of the bottom portion, which are opposed to each other, and which enable the securing member to be installed on upper edges of the installing pieces, and plate-form holding pieces which extend to the upper side from two sides of the bottom portion, which are substantially perpendicular to the two sides from which the installing pieces extend, so as to be higher than the installing pieces, are coupled to the installing pieces in a continuous manner at lower positions with respect to the upper edges of the installing pieces, and are capable of holding the securing member in a state where upper portions of the holding pieces with respect to the installing pieces nip the securing member.
