Picture Hanging Plate With 2D Offset Openings for Fine Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanging devices for objects like framed pictures and paintings lack the ability to provide both horizontal and vertical adjustment, requiring precise nail placement on the wall, which is inconvenient and can result in tilting or misalignment.
Innovation Solution
A hanging device with a planar body featuring a two-dimensional pattern of offset openings that allow for horizontal and vertical repositioning by selecting different nail insertion points, enabling precise adjustment without needing to move the nail or the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single nail is used to hang the object, then the hanging operation is simple, but the object cannot be adjusted horizontally or vertically
Solution Approach 1:
The patent transitions from a one-dimensional adjustment (single horizontal row of notches) to a two-dimensional adjustment pattern (staggered rows of notches arranged in a triangular lattice). This allows the nail to engage with notches at different horizontal and vertical positions, providing both horizontal and vertical adjustment capabilities while maintaining simple operation.
2Ease of operation
If multiple notches are provided in a single row, then horizontal adjustment is possible, but vertical repositioning is not achievable
Solution Approach 1:
The patent adds a second dimension by arranging notches in multiple staggered rows rather than a single row. The notches in adjacent rows are offset horizontally, creating a two-dimensional grid pattern that enables both horizontal and vertical positioning adjustments.
3Adaptability or versatility
If the nail position on the wall is moved to achieve repositioning, then adjustment is possible, but this requires moving the nail which is undesirable
Solution Approach 1:
The patent makes the hanging device dynamic by providing multiple engagement points (notches) that can selectively engage with a fixed nail. The user can choose which notch to engage with the nail to achieve the desired position, eliminating the need to move the nail itself.
4Adaptability or versatility
If hanging devices are moved on the object to achieve repositioning, then adjustment is possible, but this may cause damage to the object and is time-consuming
Solution Approach 1:
The patent prepares multiple pre-positioned notches in advance on the hanging device, allowing the user to simply select the appropriate notch for the desired position without moving or adjusting the hanging device itself. This preliminary arrangement of notches saves time and prevents damage to the object.

AI summary
A device for hanging an object on a vertical structure, such as a framed picture or painting on a wall. The device comprises a body having a planar portion that lies in a plane defining a first direction and a second direction transverse to the first direction. A plurality of openings are present in the planar portion, and the openings are arranged in a two-dimensional pattern so that each opening is offset in the first and second directions from at least a second of the openings. The device further includes a feature for securing the body to the object.
