Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing bottle cap opening and closing devices often struggle to open container bottles when the bottle cap and body are excessively tightened, leading to potential damage and failure in opening or tightening the cap.

Innovation Solution

A bottle cap opening and closing device featuring a base with a rotatable bottle body clamping mechanism, a buffer mechanism between the clamping mechanism and the base, and a rotation driving mechanism that allows the bottle body to rotate relative to the bottle cap, applying greater torque for easier opening or tightening, while preventing excessive tightening that could damage the bottle.

VSEngineering Contradiction Analysis

1Reliability

If the bottle cap and bottle body are excessively tightened, then the sealing performance is improved, but the device cannot open the container bottle and may cause damage

Engineering Contradiction:

Improvesealing performanceVSAvoidease of opening

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of applying rotational force to the bottle cap as in traditional devices, this invention applies rotational force to the bottle body through the bottle body clamping mechanism. This inversion of the rotation target allows the threaded connection to be undone by rotating the body rather than the cap, effectively solving the problem of excessively tightened caps that cannot be opened.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The first buffer mechanism is arranged between the bottle body clamping mechanism and the base to absorb excessive tightening forces beforehand. This cushioning mechanism prevents damage to the bottle or device when the cap and body are overtightened, while still allowing the rotation driving mechanism to apply sufficient torque to open the container.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Force

If the bottle body clamping mechanism applies rotational force to the bottle body, then the torque is greater and it is easier to open or tighten the bottle cap, but the device complexity increases

Engineering Contradiction:

ImprovetorqueVSAvoiddevice complexity

Core Design Contradiction:

ForceVSDevice complexity

Solution Approach 1:

The rotation driving mechanism serves multiple functions: it can tighten the bottle cap by rotating the bottle body in one direction, and it can open the bottle by rotating the bottle body in the opposite direction. This multi-functionality achieves both tightening and opening operations with a single mechanism, avoiding the need for separate mechanisms for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bottle body clamping mechanism is rotatably arranged on the base, allowing it to dynamically rotate relative to the stationary bottle cap clamping mechanism. This dynamic rotation capability enables the application of greater torque during tightening while maintaining ease of operation during opening, as the system can adapt its mechanical advantage based on the operational phase.

Inventive Principle:

Principle #15Dynamics

Core Design Contradiction:

Solution Approach 1:

The first buffer mechanism acts as an intermediary element between the bottle body clamping mechanism and the base. It mediates the forces applied during tightening by absorbing excessive forces while allowing sufficient forces to pass through for effective tightening and opening operations. This intermediary buffer protects the bottle and device from damage without significantly complicating the overall system.
