Solution Overview

Problem

Existing chutes face challenges in height adjustment, as precise and tedious operations are required for screw-based adjustments, and multiple spacer sets are necessary for spacers-based designs, making them cumbersome and impractical.

Innovation Solution

A chute design featuring a bowl and lid with height-adjustable spacer bodies that can switch between two contact positions by rotating 90°, allowing easy and quick height adjustment without high precision, utilizing spacer bodies with distinct face orientations and tabs for secure positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screw-based height adjustment is used, then height adjustability is achieved, but the adjustment operation becomes tedious and time-consuming

Engineering Contradiction:
Improveheight adjustabilityVSAvoidadjustment operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The adjustment mechanism is segmented into discrete spacer bodies with predetermined heights, allowing selection rather than continuous adjustment. Each spacer body is a self-contained unit with specific dimensional characteristics, eliminating the need for tedious screw adjustments while maintaining height adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention changes the parameter of height adjustment from continuous (screw-based) to discrete (spacer-based with predetermined heights). The spacer bodies have fixed heights corresponding to different installation scenarios, transforming the adjustment process into a simple selection and positioning operation rather than precise manual adjustment.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple spacer sets are provided for different heights, then height adaptability is achieved, but device complexity increases

Engineering Contradiction:
Improveheight adaptabilityVSAvoidnumber of spacer sets
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each spacer body is designed with multiple functional faces: two opposite faces for contacting the bowl and lid, and two other opposite faces for alternative positioning. This multi-functionality allows a single spacer body type to serve multiple height adjustment needs by rotating 90 degrees, eliminating the requirement for multiple dedicated spacer sets.

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

Solution Approach 2:

The spacer body incorporates rotational capability (90-degree rotation) to dynamically change its effective height. This dynamic reconfiguration allows the same physical component to provide different height adjustments based on its orientation, reducing the total number of components needed while maintaining adaptability.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If precise screw adjustment is required, then height precision is improved, but manufacturing and installation time increases

Engineering Contradiction:
Improveheight precisionVSAvoidadjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The spacer bodies are pre-manufactured with precise predetermined heights and dimensional characteristics. The precision work is performed during manufacturing rather than during installation, allowing quick selection and positioning during installation without requiring precise adjustment operations on-site. The tabs and receiving orifices are also pre-formed for accurate positioning.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The spacer bodies are designed as simple, inexpensive components that can be easily replaced if needed. Their simple geometry (parallelepipedal portion with tabs) makes them cost-effective to manufacture, and their predetermined precise dimensions provide accurate height adjustment without requiring complex adjustment mechanisms or significant installation time.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
