Solution Overview

Problem

Existing drinking container covers are prone to accidental opening due to collision with foreign objects, leading to spillage and inconvenience during carrying.

Innovation Solution

A container cover design featuring a handle ring with a restraining channel that prevents foreign objects wider than the channel from accidentally opening the drinking opening, while allowing manual operation by a finger or narrower part to unlock it safely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a button is used to open the drinking spout, then the drinking opening can be easily accessed, but the button may accidentally open the drinking spout due to collision with foreign objects

Engineering Contradiction:
Improveease of opening drinking spoutVSAvoidaccidental opening prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The handle ring acts as an intermediary component between the button and the external environment. It provides a protective barrier that mediates the interaction between foreign objects and the button, allowing intentional access while blocking accidental activation. The handle ring structure with its opening and wall design creates a controlled interface that preserves ease of operation while enhancing reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the button is fully exposed, then it can be easily pressed to open the spout, but it becomes vulnerable to accidental activation by foreign objects

Engineering Contradiction:
Improvebutton accessibilityVSAvoidforeign object impact
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The handle ring applies local quality protection by creating a differentiated structure: the opening provides localized accessibility for intentional button pressing, while the side wall provides localized protection against foreign object impact from specific directions. This local quality approach allows the button to remain accessible while being protected in the critical areas where accidental activation is most likely to occur.

Inventive Principle:
Principle #3Local quality

3Reliability

If a protective structure is added around the button, then accidental opening is prevented, but the device complexity increases

Engineering Contradiction:
Improveaccidental opening preventionVSAvoidcover structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The handle ring serves multiple functions simultaneously: it provides structural support for the cover, creates the opening for button access, provides protective barriers against foreign objects, and defines the operational interface. By making the handle ring multi-functional, the design achieves reliable protection without adding separate protective components, thereby minimizing the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention discloses a container cover and a drinking container. The container cover includes a cover body, a first upper cover, a button, and a handle ring. The cover body is provided with a first drinking opening, and the first upper cover can move between a first position where the first drinking opening is covered and a second position where the first drinking opening is not covered. The button can move between a latching position and an unlatching position relative to the cover body and the first upper cover, the handle ring can move between a locking position and an unlocking position by rotating relative to the cover body, and a restraining channel is configured on the handle ring to pass through front and rear sides of the handle ring. The handle ring in the locking position is configured to inhibit movement of the button from the latching position to the unlatching position by squeezing the button from outside the restraining channel, but not inhibit movement of the button from the latching position to the unlatching position by squeezing the button through the restraining channel. The container cover solves the technical problem that the cover opening button of the existing water drinking container is easily hit by foreign objects and accidentally opens the drinking opening.
