Solution Overview
Problem
Existing door holders lack adjustability to accommodate varying distances between doors and support surfaces, requiring multiple interchangeable parts and expert installation for precise fitting.
Innovation Solution
A door holder assembly with a base member and holder member that allow telescopic coupling, enabling adjustable positioning and attachment to surfaces through a connector system with internal and external threads, compression members, and optional shaft extenders for extended reach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional door holders are used, then the structure is simple, but the adjustability to accommodate varying distances is poor
Solution Approach 1:
The door holder is divided into separate modular components: a base member, a holder member, and a connector. This segmentation allows each component to be independently manufactured and assembled, enabling adjustability while maintaining relative structural simplicity. The base member attaches to the wall, the holder member provides the adjustable arm, and the connector facilitates easy assembly and disassembly.
Solution Approach 2:
The connector enables dynamic adjustment of the holder member's position relative to the base member. Through the connector's coupling mechanism, the holder member can be positioned at various distances and angles, transforming the static structure into a dynamic, adjustable system that adapts to different installation scenarios.
2Adaptability or versatility
If multiple interchangeable parts are used, then the adjustability is improved, but the ease of installation deteriorates
Solution Approach 1:
The connector is designed as a universal coupling component that works with both the base member and the holder member. This single multi-functional connector eliminates the need for multiple specialized interchangeable parts, simplifying the installation process while maintaining full adjustability. The connector's universal design allows for easy assembly and disassembly without requiring expert knowledge.
3Manufacturing precision
If expert installation knowledge is required, then the manufacturing precision is improved, but the productivity deteriorates
Solution Approach 1:
The door holder assembly is designed to be self-aligning and self-adjusting. The connector's coupling mechanism automatically positions the holder member correctly relative to the base member, eliminating the need for expert installation knowledge. The telescopic design allows the holder member to self-position at the correct distance, enabling DIY installation while maintaining precise fitting.
Solution Approach 2:
The connector is pre-configured with the appropriate coupling mechanisms and alignment features during manufacturing. This preliminary preparation ensures that the assembly requires no complex installation procedures, as all alignment and positioning actions are built into the components themselves, allowing for rapid, expert-free installation.
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
Facilitates easy installation and adjustment without expert knowledge, reducing the need for multiple parts and allowing flexible door opening distances, enhancing installation efficiency and reducing waste.
Implementation Method 1
The connector comprises a collar having internal threads, wherein the internal threads of the collar are operatively coupled to the external threads of the distal base end of the base member to operatively couple the shaft of the holder member to the base member
Implementation Method 2
The compression member is located between the shaft and the collar, and the collar compresses the compression member to operatively couple the shaft to the base member

AI summary
A door holder and release assembly that is adjustable to account for different differences between the door and where the door holder and release assembly will be installed (e.g., a wall, the floor, another support location). The door holder herein has a base member, a holder member, and a connector. The base member may be configured for operative coupling with a wall or a door. The holder member may be configured for operative coupling with a release assembly on the wall or the door opposite the base member. Moreover, the holder member may be configured to be telescopically operatively coupled with the base member through the connector to position the holder member at varied distances from base member to allow for the accommodation of varying distances between a wall and the door, as well as for minor adjustments that a user may want to make.
