Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for hanging pictures, photos, or awards level on walls are often cumbersome, inflexible, and lack the ability to easily mark and install multiple hanging devices at desired locations.
Innovation Solution
A flexible, rollable thin strip with a slidable spirit level and thumbtacks or pushpins that can be aligned with the frame's hanging strap or pre-drilled holes, allowing for precise leveling and marking of hanging device locations on a wall, enabling easy installation of hooks, nails, or screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional level tools (steel strips, rulers) are used, then leveling precision is improved, but device portability and storage compactness deteriorate
Solution Approach 1:
The patent employs a flexible tape strip as the base structure, allowing the leveling tool to be rolled up to a compact size for portability while maintaining the necessary rigidity through fabric construction and printed measurement markings to provide accurate leveling functionality
Solution Approach 2:
The invention transitions from rigid two-dimensional steel strips to a flexible one-dimensional tape that can be rolled along its length, adding the dimension of compact storage while preserving the functional surface area needed for leveling measurements
2Stability of the object's composition
If rigid fabric or metal strips are used, then structural stability is improved, but flexibility and rollability deteriorate
Solution Approach 1:
The patent uses a fabric tape construction that provides inherent flexibility for rolling and storage, while adding structural stability through fabric weave density, printed reinforcement markings, and the rigidity of the attached spirit level and locator pin components
Solution Approach 2:
The invention combines fabric material with printed markings and attached rigid components (spirit level, locator pins) to create a composite structure that exhibits both flexibility from the fabric base and structural stability from the rigid attachments and fabric tension
3Adaptability or versatility
If multiple locator pins are added, then adaptability for different hanging points is improved, but device complexity increases
Solution Approach 1:
The patent divides the locator pin function into multiple independent pins that can be positioned at different locations along the tape, allowing each pin to serve specific hanging point requirements while maintaining the simplicity of individual pin components
Solution Approach 2:
The locator pins serve multiple functions: marking hanging device locations, indicating level positioning, and providing reference points for various picture frame configurations, reducing the need for separate specialized tools
