Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a frame fastening hook is used for foam-free installation, then the frame can be suspended on wall fastening screws, but the positioning precision and adjustability during installation are insufficient
Solution Approach 1:
The frame fastening device incorporates adjustable components that allow dynamic repositioning during installation. The fastening position can be adjusted along the longitudinal axis of the hook body, enabling precise positioning while maintaining a relatively simple overall structure. This dynamic adjustability resolves the contradiction between positioning precision and device complexity.
Solution Approach 2:
The fastening device is segmented into modular components including the hook body, adjustable fastening mechanism, and limiting means. This segmentation allows each component to perform its specific function independently, achieving precise positioning control without requiring a overly complex integrated design.
2Adaptability or versatility
If the frame fastening hook has a fixed fastening position, then the structure is simple, but the adaptability to different installation positions is limited
Solution Approach 1:
The fastening device transitions from a fixed position design to a dynamic adjustable design. The adjustable mechanism allows the fastening point to be repositioned along the hook body, providing adaptability to different installation requirements while keeping the structural complexity manageable through straightforward mechanical adjustment features.
Solution Approach 2:
The frame fastening hook is designed with multi-functional capabilities, serving both as a suspension element and an adjustable positioning device. The same hook body accommodates various fastening positions, making it universally applicable to different installation scenarios without requiring multiple specialized components.
3Ease of operation
If the elongated opening is made larger for easier screw insertion, then the ease of operation improves, but the lateral stability of the screw head decreases
Solution Approach 1:
The elongated opening exhibits local quality variation along its length. The opening is wider at the insertion end to facilitate easy screw insertion, while the rear portion narrows to provide lateral stability and prevent excessive movement of the screw head. This localized dimensional variation simultaneously achieves ease of operation and structural stability.
Solution Approach 2:
The dimensions of the elongated opening are strategically varied along its longitudinal axis. The opening width parameter changes from larger at the insertion end to smaller at the rear, creating a gradient that balances ease of screw insertion with lateral stability retention.

AI summary
The invention relates to a frame mounting hook (10) that can be attached to the back of a frame in order to hang the frame on a wall-side mounting screw inserted into a door jamb during foam-free installation. Accordingly, the frame mounting hook (10) has a hooking area (12) for engaging the screw head of the wall mounting screw. The hooking area (12) has an elongated opening (14) for the slidably interlocking reception of the screw head of the wall mounting screw.To functionally improve the frame fixing hook, in particular to enable better positioning of the frame, it is proposed that the frame fixing hook (10) further comprise a frame fixing device (16) for attaching the frame fixing hook (10) to the frame, which is adjustable to set the position at which the frame fixing hook (10) is attached to the frame in a direction transverse to the extension of the elongated opening (14). In particular, an adjustable stop, such as a limiting element removable from an elongated hole (24), is provided.
