Tree Stand Clamping Lever With Force-Reached Signal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tree stand clamping devices lack user acceptance due to difficulties in determining the final clamping force, risk of over-tightening, and potential for insufficient clamping, leading to accidents and device damage.
Innovation Solution
A tree stand with a signaling device that acoustically or visually indicates when the required holding force is reached, preventing further tightening and ensuring secure clamping, while minimizing mechanical stress on the device components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamping force is increased to ensure secure tree clamping, then the reliability of tree fixation is improved, but the risk of device damage and accidents increases due to over-tightening
Solution Approach 1:
The patent implements an acoustic signaling device that provides feedback to the user when the optimal clamping force is reached. The signaling device emits an acoustic signal when the clamping lever reaches a predetermined position, indicating that sufficient clamping force has been applied. This feedback mechanism prevents users from applying excessive force that could damage the device or cause accidents, while ensuring reliable tree fixation is achieved.
2Reliability
If the clamping force is increased to prevent insufficient clamping, then the safety against accidents is improved, but the user cannot determine when the final clamping position has been reached
Solution Approach 1:
The acoustic signaling device provides clear feedback information to the user about the clamping status. When the clamping lever reaches the predetermined position corresponding to sufficient clamping force, the signaling device emits an acoustic signal. This resolves the information loss by clearly indicating to the user when the final clamping position has been achieved, eliminating uncertainty about whether adequate clamping has been applied.
3Reliability
If a securing element is added to prevent unintentional loosening, then the reliability of clamping is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a signaling device as an intermediary component that communicates the clamping status to the user through acoustic signals. This intermediary provides reliability enhancement by ensuring users know when proper clamping is achieved, without requiring complex mechanical securing elements that would prevent unintentional loosening. The signaling approach adds minimal complexity compared to mechanical interlocking mechanisms.

AI summary
The clamping device (2) has ratchet clamping lever (3) that communicates with movable holding elements (4). The holding elements are operatively connected and bought close into contact with log of tree stand to be clamped, during operation of the clamping lever. The holding elements firmly hold the log of tree stand while required holding force is reached. A signaling device emits signal based upon predetermined limit value of holding force. An independent claim is included for a Christmas tree stand.
