Angler's Method Feeder Mould with Moveable Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing method feeder moulds fail to effectively release ground bait from the mould without loss when the bait consistency is off, due to suction effects caused by the curved mould recess, leading to bait disintegration or weakening during removal.
Innovation Solution
A method feeder mould with a moveable surface or surfaces that are slidably movable with respect to the mould body, allowing for a concave cavity design with a biased moveable floor that shifts from a moulding to a release position, facilitating the removal of the baited feeder without tension or disintegration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plain curved mould recess is used, then the mould structure is simple, but the ground bait sticks to the mould and disintegrates during removal due to suction effects
Solution Approach 1:
The mould incorporates a moveable floor that can shift position dynamically. During moulding, the floor is in a first position to compact the ground bait. During removal, the floor moves to a second position that reduces suction effects and prevents bait disintegration, allowing the baited feeder to be extracted intact.
Solution Approach 2:
The mould is divided into separate functional components: a stationary mould body and a moveable floor assembly. This segmentation allows the floor to independently change position relative to the mould body, enabling the transition between moulding and removal phases without moving the entire mould structure.
2Adaptability or versatility
If the ground bait consistency is not perfectly mixed, then the bait may be too wet or too dry, but the plain mould cannot accommodate variations in moisture content
Solution Approach 1:
The moveable floor provides dynamic adjustment capability that adapts to variations in ground bait consistency. Whether the bait is slightly wet or dry, the floor can move to the appropriate position during removal to minimize suction effects, making the mould versatile across different bait mixing conditions.
3Reliability
If a moveable floor is added to the mould, then the bait can be released without disintegration, but the device complexity increases
Solution Approach 1:
A moveable floor is incorporated into the mould structure that can shift between a first position during moulding and a second position during removal. This dynamic component enables the baited feeder to be extracted from the mould without disintegration or loss, directly resolving the technical contradiction between reliability and complexity.
4Force
If the suction effect is strong during removal, then the bait adheres to the mould, but this causes tension that weakens or disintegrates the bait mass
Solution Approach 1:
The moveable floor reduces the suction effect during removal by changing its position relative to the mould cavity. This dynamic adjustment decreases the adhesion force between the bait and mould surface, preventing the tension that would otherwise weaken or disintegrate the bait mass during extraction.
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
Enables the successful removal of ground bait from the feeder without loss, maintaining the bait's integrity by reducing suction effects and allowing for easy release from the mould.
Implementation Method 1
The movable surface or surfaces are preferably biased towards a moulding position and moveable against the bias to a release position
Implementation Method 2
The movable surface or surfaces are preferably biased towards a moulding position and moveable against the bias to a release position
Implementation Method 3
the plain curved mould recess causes a suction effect that tends to place the moulded bait in tension as the feeder is removed from the mould
