Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tissue holders face challenges with inefficient attachment and detachment due to the high effort required for suction cup fixation, varying attachment forces needed for different sizes, and difficulty in repositioning without damaging the wall structure.
Innovation Solution
A reusable tissue holder design featuring a bar frame with a suction cup and a mechanism that generates negative pressure using a pipe barrel and linkage mechanism, allowing for easy attachment and detachment by controlling air flow through channels and valves, reducing the force needed for fixation and enabling repositioning without wall damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a suction cup is used to attach the tissue holder to the wall, then the holder can be repositioned without damaging the wall, but significant effort is required to attach and detach the holder
Solution Approach 1:
The patent employs a suction cup mechanism that utilizes atmospheric pressure differential to create strong adhesion between the holder and wall surface. The suction cup forms a sealed cavity where air is evacuated, creating negative pressure that holds the holder firmly in place without requiring mechanical fasteners or adhesives.
Solution Approach 2:
The patent incorporates a movable pressing block that can shift position to control the communication between the suction cup's internal cavity and the external atmosphere. When the pressing block moves to open the air passage, air enters the cavity, equalizing pressure and releasing the suction effect, enabling easy detachment without excessive force.
2Reliability
If a large suction cup is used to increase adsorption capacity, then the holder can be securely fixed, but more effort is required to squeeze and attach it
Solution Approach 1:
The patent introduces an air passage as an intermediary mechanism that controls the pressure differential within the suction cup. By managing the flow of air into and out of the suction cavity, the system achieves strong fixation with reduced manual effort, as the pressure control mechanism amplifies the effectiveness of the applied force.
Solution Approach 2:
The patent replaces the need for purely mechanical compression with a pneumatic control system. Instead of relying solely on mechanical force to maintain adhesion, the system uses controlled air flow to regulate the pressure differential, reducing the continuous mechanical effort required to maintain secure fixation.
3Reliability
If the suction cup is tightly attached to the wall, then the holder is securely fixed, but it becomes very difficult to detach the holder
Solution Approach 1:
The air passage serves as a controlled intermediary that manages the pressure differential. By opening this passage, external air enters the suction cavity, eliminating the negative pressure that creates adhesion. This allows the holder to be detached easily without excessive force, as the pneumatic control mechanism reverses the suction effect.
Solution Approach 2:
The system transitions from a static strong adhesion state to a dynamic controllable state. The movable pressing block enables the user to switch between attached and detached states by controlling air flow, making detachment as easy as attachment rather than requiring forceful removal.
4Reliability
If traditional fixing methods like bolts or adhesive tape are used, then the holder is securely fixed, but the wall structure is damaged when the holder is removed
Solution Approach 1:
The patent uses atmospheric pressure differential through a suction cup mechanism to achieve secure fixation without mechanical fasteners or chemical adhesives. The suction cup creates a sealed cavity where evacuated air generates negative pressure, producing strong adhesion that holds the holder firmly to the wall surface while leaving no traces or damage upon removal.
