Sanitary Fixture Recessed Installation Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary fixture recessed installation structures face challenges in height adjustment due to the need to support the frame and tighten leg screws to prevent legs from sliding back, altering the set height under the weight of the structure.
Innovation Solution
A sanitary fixture recessed installation structure with a telescopically adjustable height system featuring legs with friction members that cooperate with inner lateral surfaces of guide seats to maintain the set height without requiring manual support, allowing easy and secure height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legs are inserted telescopically inside posts with screws for securing, then the structure allows height adjustment, but the legs slide back inside posts under weight requiring manual support during adjustment
Solution Approach 1:
The friction member applies preliminary frictional resistance to prevent the leg from sliding back inside the post under the weight of the frame. This counteracts the gravitational force before the leg can move, eliminating the need for manual support during height adjustment.
Solution Approach 2:
The friction member enables the height adjustment system to support itself without external assistance. The frictional force generated between the friction member and the post automatically prevents leg slippage, making the system self-sustaining during the adjustment process.
2Ease of operation
If friction members are added to legs, then manual support during adjustment is eliminated, but the structure becomes more complex
Solution Approach 1:
The friction member changes the friction parameter between the leg and post interface. By increasing the friction coefficient through the friction member, the system achieves self-holding capability without complex mechanical locking mechanisms or additional support structures.
3Stability of the object's composition
If screws are used to secure legs to posts, then legs are fixed in place, but the adjustment process requires supporting the frame and tightening screws
Solution Approach 1:
The friction member allows the adjustment process to skip the time-consuming steps of manual support and screw tightening. The frictional engagement provides immediate stabilization, enabling rapid height adjustment without the sequential operations required by screw-based systems.
