Hatch for capsule unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional capsule unit hatches for sleep lack effective sound insulation and operability due to the use of roll blinds, which fail to block sounds and can be difficult to open and close in limited spaces without hitting objects or people.
Innovation Solution
A capsule unit hatch featuring a plate-shaped member that covers the opening entirely, supported by an inward opening mechanism allowing it to rotate and move inside the capsule unit for opening and closing, with optional cushioning and frame members for enhanced sound insulation and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a heavy opening door is installed to obtain sound insulation, then sound insulating property is improved, but opening and closing operability is deteriorated
Solution Approach 1:
The door is divided into a first door portion and a second door portion that can move relative to each other. The first door portion remains fixed to maintain sound insulation, while the second door portion moves along a guide to enable opening and closing operations without requiring the entire door to be heavy and cumbersome.
Solution Approach 2:
The door structure transitions from a two-dimensional flat plane to a three-dimensional configuration with the second door portion extending outward when opened. This allows the door to achieve both sound insulation when closed and operational accessibility when opened, resolving the contradiction between maintaining sound barrier and enabling easy operation.
2Ease of operation
If a roll blind is used for opening and closing, then ease of operation is maintained, but sound insulating property is deteriorated
Solution Approach 1:
The door is segmented into a fixed first door portion that provides sound insulation and a movable second door portion that enables operation. This segmentation allows the system to maintain sound blocking capability while providing ease of operation through the movable portion.
Solution Approach 2:
The second door portion acts as an intermediary element between the fixed sound-blocking first door portion and the external environment. It allows operational access without compromising the sound insulation provided by the first door portion.
3Object-affected harmful factors
If a heavy opening door is installed to obtain sound insulation, then sound insulating property is improved, but risk of hitting objects or people is increased
Solution Approach 1:
By dividing the door into fixed and movable portions, the system maintains sound insulation through the fixed first door portion while the lighter second door portion can be safely operated without posing significant impact risk to surrounding objects or people.
Solution Approach 2:
The door opens in a direction that utilizes the capsule unit's internal space, with the second door portion moving along a guide. This dimensional change in opening direction allows the door to clear external objects and people, eliminating the risk of impact while maintaining sound insulation when closed.

AI summary
Provided is a hatch for a capsule unit which opens and closes an opening of a capsule unit for sleeping. The hatch comprises: one plate-shaped member configured to cover the whole of the opening; and an inward opening mechanism that supports the plate-shaped member so as to be movable between a position at which the plate-shaped member is accommodated inside the capsule unit so that the opening is in an open state and a position at which the plate-shaped member covers the whole of the opening so that the opening is in a closed state.
