Wall Hook Assembly With Independent Distance and Rotation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall hooks cannot adjust the distance and orientation of the hook part independently, limiting their flexibility in aligning with anchoring bases.
Innovation Solution
A wall hook design featuring a fastening element with a screw or nail and a hook element that can be plugged or screwed onto the fastening element, allowing the hook part to be rotated and aligned independently, with a stop element that is inserted into the anchoring base to secure the hook element at a desired distance and prevent unwanted twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wall hook is screwed into the anchoring base with the hook part aligned in a predetermined direction, then the hook part can be securely fastened, but the distance and orientation cannot be adjusted independently
Solution Approach 1:
The wall hook is divided into separate components: a fastening element (screw) and a hook element that can be independently positioned. The hook element includes a shaft receptacle that receives the fastening element shaft, allowing the hook part to be oriented independently from the fastening direction. This segmentation enables separate adjustment of distance (via shaft length) and orientation (via hook element rotation).
Solution Approach 2:
The hook element is designed to be rotatable about the longitudinal axis during the fastening process, allowing dynamic adjustment of orientation. The shaft receptacle encloses the shaft by more than half in the circumferential direction, providing guidance while permitting rotation. This dynamic capability allows the hook part to be aligned in any desired direction independent of the screw insertion angle.
2Adaptability or versatility
If the hook element is rotatably attached to the fastening element, then arbitrary orientation is possible, but the hook part cannot be secured at a predetermined distance
Solution Approach 1:
The shaft of the fastening element is designed with a predetermined length that extends beyond the shaft receptacle when the hook element is attached. This preliminary extension of the shaft provides a built-in stop that automatically limits the distance between the hook part and the anchoring base, eliminating the need for additional adjustment mechanisms while maintaining precise positioning.
Solution Approach 2:
The shaft acts as an intermediary element between the fastening element head and the hook element. It transmits the fastening force while its extended length provides a mechanical stop that prevents over-rotation and maintains the hook part at a predetermined distance from the anchoring base, ensuring both orientability and positional stability.
3Ease of operation
If the shaft receptacle encloses the shaft by more than half in the circumferential direction, then the hook element is guided during insertion, but rotation about the longitudinal axis is restricted
Solution Approach 1:
The shaft receptacle is designed with a specific geometric configuration that changes its constraint characteristics during the fastening process. During initial insertion, the receptacle walls guide the shaft to ensure proper positioning. As the hook element is rotated into its final orientation, the receptacle's open configuration (enclosing less than half circumferentially) permits the necessary rotational movement to achieve arbitrary alignment.
4Adaptability or versatility
If the fastening element shaft is elongated in the longitudinal direction, then the hook element can be positioned at adjustable distances, but the structural strength is reduced
Solution Approach 1:
The fastening system is segmented into the fastening element (screw) that provides structural strength and the hook element that provides positioning flexibility. The shaft of the fastening element is elongated to extend beyond the shaft receptacle, creating a built-in stop that determines the distance. This segmentation allows the shaft to be long for adjustability while the screw thread and head provide the necessary structural strength.
Solution Approach 2:
The shaft is designed with asymmetric length distribution: a substantial portion is enclosed by the shaft receptacle for strength and guidance, while an extended portion protrudes to provide the positioning stop. This asymmetric configuration optimizes both strength (enclosed portion) and adjustability (extended portion) simultaneously.

AI summary
The invention relates to a wall hook (1) for securing in an anchoring base. The aim of the invention is to allow a hook part (12) of the wall hook (1) to be aligned at any distance from the anchoring base. According to the invention, this is achieved in that the wall hook (1) comprises a stop element (5) which extends away from a hook element (4) parallel to a longitudinal axis (L), said hook part (12) being rotatable about the longitudinal axis (L) relative to the stop element (5).
