Solution Overview

Problem

Existing extensible support feet for structures and machinery lack the ability to measure the weight borne on them, which can compromise safety and lead to inaccurate waste compactor fullness detection due to variations in waste hardness and positioning.

Innovation Solution

An extensible support foot with a weighing device featuring a resilient element, such as a helical compression spring, that measures weight by evaluating deformation, and a display system to show the measured weight, ensuring accurate weight measurement and reduced wear from foreign bodies and atmospheric agents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a resilient element is added to measure weight, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveweight measurementVSAvoidsupport foot structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The weighing function is merged with the existing support foot structure by integrating the resilient element between the first and second bodies, eliminating the need for separate weighing equipment and reducing overall system complexity despite adding measurement capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The resilient element acts as an intermediary component that indirectly measures weight through deformation, allowing weight measurement without direct contact sensors or complex measurement systems on the load-bearing surfaces

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the resilient element is exposed, then device complexity is reduced, but reliability deteriorates due to wear from foreign bodies and atmospheric agents

Engineering Contradiction:
Improveweighing device structureVSAvoidweighing device operation
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The resilient element is nested within the cavity of the second body, placing it inside a protective enclosure that shields it from foreign bodies and atmospheric agents while maintaining its weight measurement function through controlled deformation

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cavity structure provides beforehand protection against environmental damage and foreign body interference, ensuring the resilient element maintains optimal operation over time without direct exposure to harmful factors

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
