Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support posts for construction sites are difficult to install and disassemble quickly, and they lack secure fastening mechanisms without using fastening means, which compromises safety and ease of use.
Innovation Solution
A telescopic support post with a locking device and a spring mechanism, where a lever is used to control the surface support element's position, allowing for easy installation and disassembly by foot operation, and a locking mechanism to secure the post against surfaces without traditional fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening means are used to secure support posts to surfaces, then reliability and security are improved, but ease of installation and device complexity worsen due to additional fastening components and procedures
Solution Approach 1:
The support post utilizes its own weight and the spring mechanism to automatically secure itself to the surface. The surface support element with profile member engages with the tube opening, and the spring provides continuous pressure to maintain firm contact, eliminating the need for external fastening means while ensuring reliable installation
Solution Approach 2:
The support post employs a dynamic spring mechanism that allows the surface support element to move between retracted and projecting positions. The spring continuously exerts force to maintain firm contact between the support post and the surface, providing adaptive security without rigid fastening components
2Adaptability or versatility
If telescopic tubes are used without locking mechanisms, then ease of adjustment and adaptability are improved, but reliability and stability worsen due to inability to maintain fixed position
Solution Approach 1:
The locking device acts as an intermediary mechanism between the telescopic tubes. The locking ring engages with the tube opening to prevent unwanted movement, while the spring mechanism serves as a mediator to maintain continuous contact pressure. This allows the tubes to remain adjustable while ensuring stability when locked
Solution Approach 2:
The locking device is divided into separate functional components: a locking ring for engagement with the tube opening, a spring mechanism for providing continuous pressure, and a surface support element with profile member for surface engagement. This segmentation allows each component to perform its specific function while working together to provide both adjustability and stability
3Reliability
If complex locking mechanisms are used to secure telescopic tubes, then reliability and stability are improved, but ease of operation and installation time worsen
Solution Approach 1:
The locking device is designed to be activated by the user's own actions during installation. The surface support element is inserted into the tube opening, and the spring automatically engages to provide locking action. No additional tools or complex procedures are needed, reducing installation time while maintaining reliability
Solution Approach 2:
The locking function is extracted from complex mechanical systems and simplified to a spring-based mechanism that automatically engages when the surface support element is inserted into the tube opening. This extraction of the essential locking function eliminates unnecessary complexity while maintaining security
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
The solution provides a cost-effective, easy-to-manage mechanism for installing and securing support posts between surfaces, ensuring safety and stability without altering the post's structure, allowing for quick installation and removal while maintaining high safety standards.
Implementation Method 1
A spring within the tube is provided for acting on the stem to resiliently urge the stem, and thus the surface engaging member, in a direction out of the open end of the tube
Implementation Method 2
The lever has an inner portion in engagement with the spring within the opening of the support post. By moving the lever from the first position to the second position, and vice versa, resiliently affect the surface support element in a direction to and from the open end of the support post
Implementation Method 3
The support post can be installed in firm and solid contact against adjacent surfaces, without using fastening means for securing the post to the adjacent surfaces

AI summary
The present invention relates to a support post (2) comprising at least two tubes (4, 6) telescopically in sliding connection to each other. A locking device (8) holds the tubes in a locked state and allowing relative sliding of the tubes in an unlocked state. At least one end (10) of the support post has an opening (12; 112) in connection with a surface support element (14; 114). A spring is arranged within the opening of the support post to act on the surface support element (14; 114), to resiliently affect the surface support element (14; 114) in a direction away from the open end (10) of the support post and vice versa. The locking device (8) comprises a locking ring loosely arranged on one of the tubes (4) and further comprises a first ring holding arm arranged at one end of the other tube (6); the first ring holding arm having a first recess for retaining the locking ring in loose arrangement around said tube (4) with limited movability. A lever is in engagement with the spring and arranged in a first position in an unstressed condition of the spring. The lever is arranged in a second position in a stressed condition of the spring. By moving the lever from the first position to the second position, and vice versa, resiliently affect the surface support element (14; 114) in a direction to and from the open end (10) of the support post (2). The surface support element is arranged to be installed on a floor, and the lever is a pedal.
