Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ink-jet recording apparatuses face challenges in effectively dampening vibrations both perpendicular and parallel to the recording surface, leading to degradation in recording quality.
Innovation Solution
A recording apparatus is designed with a recording head having a gradient inclined relative to its recording surface, supported by a platen via elastic members that abut both the recording surface and the gradient, effectively dampening vibrations in both directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a vibration absorber is provided between the recording head and holder, then vibration in the direction perpendicular to the recording surface is dampened, but vibration in the direction parallel to the recording surface cannot be effectively dampened
Solution Approach 1:
The invention introduces a gradient surface inclined at an angle to the recording surface, creating a new geometric dimension. The vibration damper contacts both the inclined gradient surface and the parallel recording surface, forming a wedge-shaped contact region. This dimensional change allows the single vibration damper to simultaneously resist vibrations in both perpendicular and parallel directions through its geometric configuration rather than requiring multiple dampers for each direction.
Solution Approach 2:
The invention changes the geometric parameters of the vibration damper contact interface by introducing an inclined gradient surface with a specific angle. This parameter change transforms the contact geometry from a simple parallel surface to an inclined wedge shape, enabling the damper to effectively counteract vibrations in multiple directions simultaneously through its altered geometric configuration.
2Manufacturing precision
If multiple vibration dampers are provided to dampen vibrations in different directions, then recording quality is improved, but the apparatus structure becomes more complex
Solution Approach 1:
The invention makes a single vibration damper perform multiple functions by configuring it to contact both the inclined gradient surface and the parallel recording surface. This single component simultaneously dampens vibrations in both the perpendicular and parallel directions, eliminating the need for separate dampers for each direction and thereby reducing overall structural complexity while maintaining comprehensive vibration control.
Solution Approach 2:
The invention merges the functions of multiple vibration dampers into a single integrated component. By positioning one vibration damper to contact both the inclined gradient surface and the parallel recording surface, the design combines what would traditionally require multiple separate dampers into one unified structure, simplifying the overall apparatus while achieving comprehensive vibration dampening.
