Elastic Door Block Structure for Easy Door Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current door stops are not easily engaged and disengaged, lack versatility in placement, and often require permanent installation, failing to provide ease of use and adaptability.
Innovation Solution
A multifunctional door block with a resilient, elastic design, featuring a tapered 'U' shape and truss structure, allowing easy engagement and disengagement, and capable of being placed at various door locations, including hinges and under the door, to prevent complete closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a door stop is designed to be easily engaged and disengaged, then ease of operation is improved, but the door stop may lack stability or reliability in holding the door
Solution Approach 1:
The door block utilizes material elasticity as a variable parameter, allowing it to deform under door pressure and then rebound to maintain continuous contact and holding force. This elastic deformation enables easy engagement while maintaining reliable door holding position
Solution Approach 2:
The door block is designed with dynamic characteristics through its elastic material properties, allowing it to adapt its shape in response to applied forces. The block dynamically adjusts between engaged and disengaged states, providing both ease of operation and reliable holding when engaged
2Reliability
If a door stop is designed as a permanent fixture, then reliability is improved, but ease of operation and adaptability deteriorate
Solution Approach 1:
The door block is designed to be self-installing through its elastic properties. When pressed against the door, the block automatically deforms and secures itself without requiring screws, adhesives, or other permanent fixation methods, yet remains easily removable
Solution Approach 2:
The elastic material allows the door block to change its physical state from a compact storage form to an expanded engaged form, providing reliable holding without permanent installation. The material's elastic modulus and deformation characteristics enable this reversible transformation
3Manufacturing precision
If a door stop has a fixed design, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The door block is designed as a universal device that can be placed at multiple locations on different door types (top, side, bottom, hinge area). The elastic material and geometric design allow it to adapt to various door thicknesses and configurations while maintaining consistent manufacturing specifications
Solution Approach 2:
The door block's elastic properties allow it to accommodate variations in door dimensions and placement locations. The material can deform to fit different gaps and configurations, providing adaptability across multiple applications while maintaining a single standardized design for manufacturing
