Inverted Machine Brake Mechanism for Adjustable Angle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inverted machines lack a brake mechanism, limiting adjustable angle options and posing safety concerns due to user balance reliance, leading to potential back strain and instability during use.
Innovation Solution
Incorporation of a supporting bracket with a brake locator, rotating shaft, clamping slices, pulling rod, spring, and cam device allows for adjustable angle settings and secure user positioning, enhancing safety and usability by enabling controlled table rotation and secure holding at desired angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table is pivoted only by user body balance without a brake mechanism, then the device structure remains simple, but the user feels unsafe during pivoting and cannot adjust to different angles
Solution Approach 1:
The brake mechanism incorporates a cam device that can be manually operated to dynamically adjust the clamping force between clamping slices and the locating sheath, allowing the table to be held at various angles rather than fixed positions. This dynamic adjustment capability enables multi-angle positioning while maintaining a relatively simple mechanical structure.
Solution Approach 2:
The cam device acts as an intermediary between the user's manual input and the brake mechanism's clamping action. By operating the cam, the user can control the pulling rod which in turn adjusts the clamping slices' position, providing precise angle control without requiring complex control systems.
2Reliability
If the table rotates freely without a brake mechanism, then the device structure remains simple, but the user may lose balance and pull muscles to get back up causing back strain
Solution Approach 1:
The brake mechanism provides preliminary anti-action by enabling the user to pre-set the table at a desired angle before fully inverting. The cam device allows the user to engage the brake at any point during the pivoting motion, preventing uncontrolled rotation and eliminating the need for reactive muscle pulling to regain balance.
Solution Approach 2:
The brake mechanism allows preliminary action by enabling the user to prepare the table at a safe angle before committing to the full inversion. The user can adjust the cam position to set the brake engagement point in advance, ensuring safety before the exercise begins.
3Adaptability or versatility
If no brake mechanism is provided, then the device structure remains simple, but the table can only rotate to upright or inverted positions without intermediate angle options
Solution Approach 1:
The brake mechanism with cam device transforms the table's positioning from discrete (only upright or inverted) to continuous (any angle between 0-180 degrees). The cam's rotational movement allows incremental adjustment of the clamping slices' position, enabling smooth transition through intermediate angles.
Solution Approach 2:
The brake mechanism changes the key parameter of table rotation angle from fixed discrete values to continuously variable. By rotating the cam to different positions, the user can change the clamping force and position of the clamping slices, thereby achieving any desired rotation angle.
