Remote Trigger Head Automatic Tube Rewinding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote trigger dispensing devices face challenges in storing the long flexible tube after use, as coils wound around the handle tend to unwind and are prone to tearing, and compartment storage is cumbersome and difficult to manage.
Innovation Solution
The remote trigger dispensing device incorporates an automatic winder unit with a spring mechanism that rewinds the tube into the casing, preventing damage and simplifying storage by keeping the tube in a compact, unwound state within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the tube is wound around the handle for storage, then the tube is stored in a compact form, but the tube tends to unwind and is prone to tearing
Solution Approach 1:
The winder unit automatically winds the tube without requiring manual intervention. The spring mechanism self-activates when the tube is inserted, performing the winding action autonomously and preventing the tube from unwinding or becoming damaged during storage
Solution Approach 2:
The spring mechanism is pre-loaded and ready to wind the tube as soon as it is inserted into the winder unit. This preliminary preparation ensures the tube is immediately secured in a wound state, preventing unwinding and potential damage before storage is complete
2Ease of manufacture
If a compartment for the tube is provided in the container, then the tube has a designated storage space, but the user has difficulty inserting the coil and risks tearing the tube
Solution Approach 1:
The winder unit automatically performs the winding action without requiring the user to manually coil or insert the tube into a compartment. The spring mechanism self-activates, making the storage process effortless and eliminating the difficulty of manual insertion
Solution Approach 2:
The manual mechanical action of coiling and inserting the tube into a compartment is replaced by an automatic spring-driven winder mechanism. This substitution eliminates the complex manual operations and potential for user error or tube damage
3Length of moving object
If the tube is kept long and flexible for remote operation, then the head can be used remotely from the container, but the tube becomes difficult to store and manage
Solution Approach 1:
The tube transitions from a static long flexible state during operation to a dynamically wound compact state during storage. The winder unit enables this dynamic transformation, allowing the tube to maintain its required length for remote operation while becoming easily manageable when not in use
Solution Approach 2:
The long flexible tube is nested within itself through the winding mechanism, forming a compact coil within the winder unit. This nesting allows the tube to maintain its full length for operation while occupying minimal space during storage
