Sliding Seat Lock Mechanism for One-Step Rod Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding adjustment devices for shower equipment require multiple steps to adjust the height, making it inconvenient for users, especially special groups like the elderly, children, and disabled individuals, due to non-consistent operation and adjustment directions.
Innovation Solution
A sliding adjustment device with a movable seat and an adjustment mechanism where the drive member's operation direction aligns with the seat's adjustment direction, utilizing a transmission structure with mesh assemblies and an elastic reset member to enable one-step height adjustment, ensuring the lock member's consistent unlocking and locking states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drive member operates in a single direction to unlock the lock member, then the unlocking function is achieved, but the operation direction is inconsistent with the adjustment direction of the movable seat, requiring multi-step operation
Solution Approach 1:
The patent combines the unlocking function and the adjustment function into a single continuous operation. The drive member is designed with transmission surfaces that engage the lock member during the same directional movement that adjusts the movable seat, merging two previously separate operations (unlocking + adjusting) into one unified action, thereby improving ease of operation and reducing adjustment steps to one-step operation
2Ease of operation
If the drive member is designed to move in one direction for unlocking, then the structure is simple, but it cannot achieve consistent operation direction with the adjustment direction
Solution Approach 1:
The patent applies local quality by designing different functional surfaces on the drive member. The drive member has first and second transmission surfaces at different locations, where the first transmission surface engages the lock member for unlocking while the second transmission surface provides structural support or alternative engagement. This localized functional differentiation allows the drive member to achieve both unlocking and direction consistency without requiring complete structural redesign
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 allows for one-step height adjustment of the sliding device, improving user experience and convenience, particularly for special groups, while maintaining a compact and labor-saving operation mechanism.
Implementation Method 1
the lock member and/or the drive member are fitted with the movable seat through a reset member to make the lock member return to the first state

AI summary
A sliding adjustment device and an adjustment method therefor are disclosed in the present application. The sliding adjustment device includes a movable seat and an adjustment mechanism, the movable seat is provided with a sleeve hole through which a rod may pass; the adjustment mechanism includes a lock member and a drive member, the lock member is movably disposed at the movable seat and has a first state and a second state, the lock member enters the sleeve hole and abuts against the rod to lock the movable seat in the first state, and the lock member releases the rod to unlock the movable seat in the second state; the drive member is movably disposed at the movable seat, and is fitted with the lock member through a transmission structure, and the drive member drives the lock member to move to the second state by moving along an axial first direction of the rod or an axial second direction of the rod opposite to the first direction; the lock member and/or the drive member are fitted with the movable seat through a reset member to make the lock member return to the first state. According to the present application, an operation unlocking direction of the drive member can be consistent with the adjustment direction of the movable seat in the axial direction of the rod, so that the movable seat may be adjusted to a suitable position only by a one-step operation, which is convenient for use.
