Adjustable Holding Element With Threaded Rod And Knob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding elements for construction materials, such as plasterboards and insulating materials, lack precise and easy-to-implement adjustment mechanisms for the working length of the rod, leading to difficulties in adapting to specific thicknesses and maintaining the construction element effectively.
Innovation Solution
A holding element with a threaded rod and a circular knob that allows for precise adjustment of the working length through screwing or unscrewing, utilizing fastening plates with screwing means that cooperate with the thread to securely engage and disengage the rod, enabling easy and intuitive length adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rod with thread and screwing mechanism is used for adjustment, then the manufacturing precision and adaptability are improved, but the device complexity increases
Solution Approach 1:
The rod is nested within the knob, with the rod passing through a recess in the knob. The fastening plates are housed within the knob structure. This nesting arrangement allows the adjustment mechanism to be compact while maintaining precision, resolving the contradiction between manufacturing precision and device complexity.
Solution Approach 2:
The holding element is divided into distinct functional segments: the rod for length adjustment, the knob for securing and adjustment control, and the fastening plates for engagement. This segmentation allows each component to be optimized independently, achieving precise adjustment without excessive overall complexity.
2Ease of operation
If fastening plates with buttons are used for securing, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The fastening plates are designed with buttons that, when pressed, automatically release the rod from the knob. The spring means automatically return the plates to their securing position after release. This self-service mechanism simplifies operation while minimizing complexity through automatic resetting functionality.
Solution Approach 2:
The fastening plates are pre-positioned in a securing state, with the buttons ready to be pressed for release. The spring means are pre-loaded to automatically return the plates to their securing position. This preliminary preparation of the fastening mechanism enables quick and easy operation without complex control systems.
3Productivity
If the rod can be quickly removed and repositioned, then the productivity is improved, but the reliability of maintaining working length decreases
Solution Approach 1:
The screwing mechanism replaces simpler but less precise mechanical connection methods. The threaded engagement between the rod and the knob's screwing means provides reliable length maintenance, while the button-actuated fastening plates enable quick release. This substitution of the connection mechanism achieves both productivity and reliability.
Solution Approach 2:
The spring means provide continuous mechanical feedback by maintaining constant pressure on the fastening plates to keep them in the securing position. This feedback ensures the rod remains firmly secured at the adjusted working length during use, while allowing quick release when the buttons are pressed, thus maintaining both reliability and productivity.
