Shower Head Holder Lever Lock for Easy Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower head positioning devices on rods are difficult to operate, especially for users with slippery hands or those who are handicapped, as they require rotating a tubular locking knob which can be challenging to manage.
Innovation Solution
A height-adjusting device featuring a lever unit that allows easy operation to move and lock a holder along a rod, utilizing a spring-loaded clamp and clip system that can be operated by pushing the lever to adjust and secure the shower head position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tubular locking knob is used to lock the adjusting member to the rod, then the device can be securely locked, but it becomes difficult to operate when the user's hand is slippery or if the user is handicapped
Solution Approach 1:
The patent inverts the conventional locking mechanism by replacing a rotary knob with a push-button lever. Instead of requiring rotational motion to engage/disengage the lock, the user simply pushes the lever in a linear direction. This inversion of the operating motion makes the device accessible to users with slippery hands or disabilities who cannot perform rotational movements, while maintaining secure locking through the lever's engagement with the rod.
Solution Approach 2:
The patent replaces the rotary mechanical system with a linear push-button mechanical system. The conventional rotary locking knob is substituted with a lever that operates through linear pushing motion. This substitution changes the mechanical input from rotational to linear, making it easier for users with limited hand dexterity or wet/slippery conditions to operate the locking mechanism while maintaining the same locking reliability.
2Reliability
If a rotary locking mechanism is used, then the adjusting member can be securely locked to the rod, but it requires complex rotational operation that is difficult for handicapped users
Solution Approach 1:
The patent simplifies the operational complexity by inverting the rotary mechanism into a linear push-button mechanism. The complex rotational operation is replaced with a simple single-direction push motion, reducing the operational steps and mental load required. The locking security is maintained through the lever's mechanical engagement with the rod, which provides secure locking without requiring the user to perform complex rotational movements.
Solution Approach 2:
The patent extracts the essential locking function from the complex rotary mechanism and isolates it into a simple push-button lever. By removing the rotational component and retaining only the core locking function, the device achieves secure locking with minimal operational complexity. The lever directly engages with the rod through a simple linear motion, eliminating unnecessary rotational steps while maintaining locking reliability.
3Adaptability or versatility
If a conventional adjusting member with locking knob is used, then the shower head can be positioned at different heights, but the operation becomes cumbersome for users with slippery hands or disabilities
Solution Approach 1:
The patent maintains the height adjustment capability while inverting the operating mechanism from rotary to linear push-button. The lever can be pushed to lock at any desired height position along the rod, preserving the adaptability for users of different heights. The inverted push operation eliminates the difficulty of rotating a knob with slippery hands or limited dexterity, making the height adjustment function accessible to handicapped users while maintaining full versatility.

AI summary
An adjusting device for positioning shower head includes a holder movably connected to a rod and a clip for positioning a shower head is rotatably connected to the holder. A frame is connected to the holder and a clamp is movably located between the holder and the frame. The clamp has a clamp shoe which is in a first position to contact the rod or in a second position to be removed from the rod. The clamp has an insertion extending therefrom which extends through the frame and is connected with a lever unit. A spring is mounted on the insertion. The lever unit can pull the insertion to remove the clamp shoe away from the rod to allow the holder to be moved along the rod.
