Self-Locking Holder for Concrete Formwork Guide Shoe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holders for guide shoes in climbing systems for concrete formwork lack a reliable locking mechanism to prevent unintentional movement, posing safety risks and requiring manual intervention for secure positioning.
Innovation Solution
A holder with a self-locking drive mechanism, comprising a hold-down and a slide part with a telescopic design, where the slide part is secured against unintentional movement through a self-locking transmission, such as a threaded drive or worm transmission, allowing for easy assembly and operation without additional manipulation, and featuring a detachable release guard and anti-fall lock for enhanced safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a telescopic holder with support arm is used to project over the floor edge, then the guide shoe can be positioned correctly, but the holder lacks automatic locking and requires manual safety mechanisms
Solution Approach 1:
The drive mechanism is designed to be self-locking, automatically securing the slide part against unintentional movement without requiring manual intervention or additional safety mechanisms. The system serves itself by inherently preventing unintended motion through the properties of the drive mechanism.
Solution Approach 2:
The patent replaces complex manual safety locking mechanisms with a self-locking drive mechanism that inherently prevents unintended movement. This substitution simplifies the overall system by eliminating the need for separate safety devices while maintaining or improving reliability.
2Ease of operation
If manual safety mechanisms are used to prevent slide part movement, then positioning can be secured, but operation requires additional manipulation and time
Solution Approach 1:
The self-locking drive mechanism automatically performs the locking function without requiring manual operation. The system handles its own safety requirements through the inherent properties of the drive, eliminating the need for operators to manually engage safety mechanisms.
Solution Approach 2:
The self-locking property is built into the drive mechanism itself, so the locking action occurs automatically as part of the normal operation rather than requiring a separate preliminary safety step. The safety function is integrated into the basic operation flow.
3Reliability
If a non-self-locking drive is used, then movement is easier to initiate, but unintentional movement cannot be prevented
Solution Approach 1:
The drive mechanism automatically provides the locking force needed to maintain position without requiring external intervention. The system generates its own stabilizing force through the self-locking properties of the drive mechanism.
Solution Approach 2:
The self-locking drive mechanism acts as an intermediary between the motor and the slide part, automatically providing the necessary holding force. This intermediary component absorbs the function of force multiplication and position maintenance without requiring additional external forces or mechanisms.

Function Achieved in This Case
The solution provides secure and automatic locking of the slide part against unintentional movement, eliminating the need for manual safety mechanisms and ensuring the holder remains in place during operation, enhancing safety and ease of use by allowing movement with a rotary drive and preventing accidental detachment or slipping.
