Coffee grinder-doser with improved lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee grinder-dosers face issues with maintenance and cleaning due to the lack of a second support point for the lid, leading to potential damage from mechanical stress on electrical connections and inconvenience during operations.
Innovation Solution
A coffee grinder-doser with a hinge mechanism that allows the lid to be partially detached and supported, housing the connecting cable within the hinge to prevent mechanical stress and enable easier access for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is connected to the body by a non-removable cable for electrical connections, then the lid can be partially removed for maintenance, but the cable occupies high volume in normal use position and is subjected to high mechanical stress during handling
Solution Approach 1:
The cable is nested within the hinge structure, specifically housed in a seat formed inside the hinge. This allows the cable to be protected and organized within the existing mechanical structure, eliminating external cable encumbrances while maintaining electrical connectivity between the lid and body during maintenance operations
Solution Approach 2:
The hinge acts as an intermediary structure that simultaneously provides mechanical support for the lid and houses the electrical cable. This mediator function allows the cable to be protected from mechanical stress while still enabling the lid to be partially removed for maintenance
2Ease of repair
If the lid is removed for maintenance operations, then access to internal parts is improved, but the operator must use one hand to support the lid and the other hand for maintenance tasks
Solution Approach 1:
The hinge structure provides a nested support mechanism where the lid can be partially detached and rested on the hinge itself. This eliminates the need for manual support of the lid during maintenance operations, as the hinge structure naturally supports the lid in a partially open position
Solution Approach 2:
The hinge structure provides self-service support for the lid during maintenance operations. The lid automatically finds support on the hinge when partially opened, eliminating the need for the operator to manually hold or support the lid while performing maintenance tasks
3Adaptability or versatility
If a long cable is used to allow lid handling, then the lid can be partially removed, but the cable is subjected to high mechanical stress and may be damaged by repeated actions
Solution Approach 1:
The cable is nested within the hinge seat, which provides a protected pathway for the cable. This eliminates the need for a long external cable and prevents the cable from being subjected to mechanical stress during lid handling, as the cable moves with the hinge structure itself
Solution Approach 2:
The hinge serves as an intermediary structure that transfers the movement and stress from lid handling away from the cable. The cable is housed within the hinge, so the hinge absorbs and manages the mechanical stresses while maintaining electrical connectivity
