A cooling device comprising a position-adjustable door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling devices face challenges in properly mounting and adjusting the door due to production tolerances and uneven installation surfaces, leading to user dissatisfaction and potential door instability under load.
Innovation Solution
A cooling device with an adjustment mechanism that converts radial movement into vertical movement, using a lever-like arm to adjust the hinge and main pin, allowing easy and secure positioning of the door, supported by first and second bearings and covers to distribute weight evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door position is adjusted using oval-shaped holes for screws, then the door position can be changed, but the hole gets wider over time under load and the screw dislodges causing the door to fall off
Solution Approach 1:
A support component is introduced as an intermediary element between the hinge and the body. This support component carries the door weight and provides a stable mounting surface for the hinge, preventing the screw holes from widening and dislodging while still allowing position adjustment within design limits
Solution Approach 2:
The hinge and support component are designed to be movable relative to each other during installation, allowing position adjustment. Once positioned, they become fixed together, providing stable load-bearing connection. This dynamic approach enables both adjustability and reliability
2Reliability
If the support component is made longer than the hinge to provide support in all positions, then the hinge is always supported, but more material is consumed
Solution Approach 1:
The support component has varying lengths at different positions - longer where needed to provide hinge support and shorter where not required. This non-uniform design provides adequate support coverage while minimizing material consumption in areas where full length is not necessary
3Device complexity
If the hinge is attached directly to the body without additional support components, then the structure is simpler, but the door becomes unstable under load due to production tolerances and uneven floors
Solution Approach 1:
A support component is introduced as an intermediary element between the hinge and the body. This support component carries the door weight and provides a stable mounting surface for the hinge, preventing the screw holes from widening and dislodging while still allowing position adjustment within design limits
Solution Approach 2:
The support component is designed in advance to compensate for production tolerances and uneven installation surfaces. It provides a stable base that absorbs these variations before they affect the hinge and door, ensuring reliable operation under load

AI summary
The present invention relates to a cooling device (1) comprising at least one body (2) wherein the items to be cooled are placed; at least one door (3) which provides access into the body (2); at least one main pin (4) and at least one hinge (5) which are fixed to the door (3), which enable the door (3) to be attached to the body (2) and whereon the door (3) is mounted so as to rotate therearound; and at least one adjustment mechanism (6) with one end being accessible from the outside whereon the main pin (4) is seated, which serves as a lever when a force is exerted from the outside in a manner to move upwards/downwards in the vertical axis, thus enabling the main pin (4) and the hinge (5) to stop at the desired position and if required, enabling the position of the door (3) on the body (2) to be changed by being actuated.
