Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-hanging devices require time-consuming and inconvenient assembly and disassembly processes, especially in narrow spaces, due to the need for manual rotation of bolts and limited space between the product and the wall fixing plate.
Innovation Solution
A hanging device comprising a wall fixing plate, a wall hanging element, and a spiral spring, where the spiral spring is used to facilitate quick assembly and easy detachment by storing elastic force and distributing stress evenly, allowing for a longer actuation movement and increased yield strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts are used to lock the product on the wall fixing plate, then the product can be securely fixed on the wall surface, but the assembly and disassembly process becomes time-consuming and inconvenient
Solution Approach 1:
The wall fixing system is divided into separate components: a wall fixing plate with fixing portions, a wall hanging element with fixing members, and a spiral spring. This segmentation allows the components to be quickly assembled and disassembled without requiring tools to rotate bolts, while still providing secure fixation when engaged.
Solution Approach 2:
The spiral spring is pre-installed on the wall fixing plate in a compressed state, storing elastic potential energy before use. This preliminary action enables the spring to automatically push the wall hanging element into the fixing portions upon assembly, providing secure fixation without requiring time-consuming bolt rotation.
2Volume of moving object
If the product is assembled close to the wall surface to save space, then space is improved, but the narrow space increases the difficulty of assembly and disassembly
Solution Approach 1:
The spiral spring provides self-service by automatically pushing the wall hanging element into the fixing portions during assembly and enabling easy release during disassembly. This eliminates the need for manual manipulation in the narrow space between the product and wall, making assembly and disassembly easy even when space is minimized.
3Ease of operation
If a spiral spring is used to provide elastic force for detachment, then easy detachment is achieved, but the spring must withstand high stress in a compact space
Solution Approach 1:
The spiral spring utilizes a three-dimensional spiral configuration with varying radius, allowing it to expand and contract along the axial dimension while distributing stress throughout its coiled structure. This dimensional approach enables the spring to provide strong elastic force for easy detachment while withstanding high stress within a compact space.
Solution Approach 2:
The spiral spring is made from a material with high strength-to-density ratio, combining elasticity and strength properties. This composite material approach allows the spring to withstand the high stress required for providing strong elastic force in a compact design, ensuring both easy detachment and structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and convenient assembly and disassembly of wall-hanging elements by leveraging the elastic force of the spiral spring, ensuring sufficient force to move the element between fixed and released positions even in narrow spaces, thereby improving usability and extending the service life of the spring.
Implementation Method 1
the elastic force stored in the spiral spring drives the wall hanging element to move with respect to the wall fixing plate
Implementation Method 2
when the spiral spring is compressed, the inner stress applied to the spiral spring can be distributed over the entire spring properly, thereby increasing the yield strength and the service life of the spiral spring
