Exercise Frame Height Adjustment with Integrated Latching and Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional position adjusting devices for exercising apparatuses face issues with locking mechanisms, where latching mechanisms may not be securely detached and clamping mechanisms can become loose under weight, and combining both mechanisms requires cumbersome operation.
Innovation Solution
A height adjustment mechanism featuring a slidable block, pin member, pressing member, and connecting arms that allow for secure locking and easy release of the second frame body relative to the first frame body, using a combination of latching and clamping mechanisms with an elastic member to bias the pin member to the lock position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If latching means is used to lock the position adjusting device, then the locking reliability is improved, but the ease of operation deteriorates because the device cannot be easily detached from the selected position
Solution Approach 1:
The patent combines latching means and clamping means into a single integrated position adjusting device. The latching means (with lock pin and positioning holes) provides reliable locking, while the clamping means (with pressing member and elastic member) enables easy detachment. This merging allows the device to achieve both high locking reliability and ease of operation through the协同 action of both mechanisms.
Solution Approach 2:
The patent introduces dynamic characteristics to the locking mechanism through the elastic member that biases the pressing member. The pressing member can dynamically transition between engaged and disengaged states based on operational needs, allowing the device to switch between secure locking and easy detachment modes seamlessly.
2Ease of operation
If clamping means is used to lock the position adjusting device, then the ease of operation is improved, but the reliability deteriorates because the device may become loose when sustaining great weight
Solution Approach 1:
The patent merges clamping means and latching means into one integrated system. The clamping means (with pressing member) provides easy adjustment capability, while the latching means (with lock pin) ensures locking stability under weight. The elastic member coordinates both mechanisms to work together, maintaining reliability while preserving ease of operation.
Solution Approach 2:
The elastic member introduces dynamic biasing that keeps the pressing member in a state ready to engage or disengage as needed. This dynamic element allows the system to maintain locking stability under load while enabling easy adjustment when required, through the coordinated action of both clamping and latching mechanisms.
3Reliability
If both latching lock mechanism and clamping lock mechanism are arranged on the position adjusting device, then the reliability and ease of operation are both improved, but the device complexity increases and requires two sets of independent actions to be operated
Solution Approach 1:
The patent merges the latching lock mechanism and clamping lock mechanism into a single integrated position adjusting device with coordinated operation. The lock pin, positioning holes, pressing member, and elastic member work together as one unified system, eliminating the need for two separate independent actions while maintaining both reliability and ease of operation.
Solution Approach 2:
The integrated mechanism performs multiple functions through a single system: the latching means provides secure locking, the clamping means enables easy adjustment, and the elastic member coordinates both functions. This multi-functionality reduces device complexity by eliminating redundant separate mechanisms while achieving the desired reliability and operational ease.

AI summary
A height adjustment mechanism for exercising apparatus includes a first frame body and a second frame body being slidable relative to the first frame body in an adjusting direction. The second frame body has a series of positioning holes. A pressing member is disposed at one side of the first frame body for tightening or loosening the second frame body. A slidable block is limitedly movable along the first frame body in the adjusting direction. A pin member is received in the slidable block and operable to be engaged in a selected one of the positioning holes so that movement of the second frame body causes movement of the slidable block within a limited range. When the slidable block moves toward bottom of the limited range, the pressing member is pulled inward by at least one connecting arm to a tightening position to clamp the second frame body.
