Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottles do not allow for a simple and precise extraction of a partial amount of liquid product, leading to potential overuse or underuse of the product, especially in applications like liquid detergent.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional bottle design is used, then the bottle structure is simple, but precise dosing of liquid product cannot be achieved
Solution Approach 1:
The bottle body is designed with specific elastic parameters including a resistance threshold W and two distinct deformation sections with different force-deformation ratios. The first section has ratio m1 and the second section has ratio m2 which is at least twice m1. By controlling the elastic deformation parameters and resistance threshold, precise dosing is achieved through the elastic behavior of the bottle body itself without additional dosing mechanisms.
2Measurement precision
If manual dosing control is implemented using a measuring cup, then dosing precision can be improved, but the dispensing process becomes time-consuming and requires additional components
Solution Approach 1:
The bottle body performs the dosing function itself through its elastic deformation characteristics. When a user compresses the bottle, the resistance threshold W provides tactile feedback that automatically indicates when the predetermined dose has been dispensed. This self-dosing mechanism eliminates the need for external measuring cups and reduces dispensing time while maintaining precision.
Solution Approach 2:
The resistance threshold W provides tactile feedback to the user during compression. As the bottle body deforms elastically, the user feels the resistance increase and can detect the threshold W, which signals that the predetermined dose has been dispensed. This feedback mechanism enables precise dosing without requiring external measuring devices or complex controls.
3Stability of the object's composition
If the bottle body is made rigid for structural stability, then the bottle maintains its shape, but elastic deformation for dosing cannot be achieved
Solution Approach 1:
The bottle body is designed with specific local elastic properties in the jacket area while maintaining overall structural stability. The elastic behavior is concentrated in specific regions that allow controlled deformation during dosing, while other parts of the bottle maintain rigidity for structural support. This local quality approach enables both stability and deformability where needed.

AI summary
The invention relates to a bottle (1) for a liquid product, wherein a bottle body (10) of the bottle (1) made of plastic defines a receiving space (40) with a volume (V). When the bottle body (10) is compressed by a force (F) acting centrally on a front wall (18) of the bottle body (10) and by a counterforce (G) acting centrally on a rear wall (19) opposite to the force (F), the bottle body (10) is elastically deformed, so that the volume (V) of the receiving space (40) is reduced by a volume change (ΔV).A first section of elastic deformation up to a resistance threshold (W) can be assigned a first ratio (R1) of initial first force increase (ΔF1) to a first relative volume change (ΔV1/V), wherein a second section of elastic deformation, which begins at the resistance threshold (W) and has a length (L), can be assigned a second ratio (R2) of a second force increase (ΔF2) to a second relative volume change (ΔV2/V), wherein the resistance threshold (W) lies in a range of relative volume change (ΔV/V) of 2 to 7%, and wherein the second ratio (R2) is at least twice as large as the first ratio (R1). The invention also relates to a method for dispensing a subset from the bottle (1) by utilizing the resistance threshold (W).
