Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an overturning type opening cover is used, then the garbage can head can be opened, but the cover collides with hands resulting in poor use experience

Engineering Contradiction:
Improveuse experienceVSAvoidcollision with hand
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies the dynamics principle by replacing the static overturning cover with a dynamic roller shutter mechanism that moves vertically along guide rails. The cover transitions from a fixed position to a dynamically controlled opening/closing motion, allowing smooth operation without collision while maintaining sealing functionality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent replaces the traditional mechanical overturning hinge system with an automated roller shutter mechanism driven by a motor. This substitution eliminates the need for manual overturning motion that causes hand collision, providing a more safe and comfortable user experience.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If an overturning type opening cover is used, then the garbage can head can be opened, but the cover cannot be fully opened in narrow spaces

Engineering Contradiction:
Improveapplicability in narrow spaceVSAvoidopening capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The roller shutter mechanism provides dynamic adjustability in opening distance. The motor-driven system can open the cover to any degree required, allowing full opening in narrow spaces without the geometric constraints of traditional overturning hinges. The vertical motion along guide rails enables complete retraction when space is limited.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If a roller shutter-type intelligent garbage can head is used, then collision-free operation is achieved, but the device complexity increases

Engineering Contradiction:
Improvecollision avoidanceVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent segments the cover system into distinct functional components: the roller shutter cover itself, guide rails for vertical motion, a motor for driving, and sensor systems for control. This segmentation allows each component to be optimized independently while working together to achieve collision-free operation through coordinated function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces sensors as intermediary elements between the user and the cover mechanism. These sensors detect hand proximity and control motor activation, mediating the interaction to prevent collision while managing the complexity of automated control through intelligent sensing rather than complex mechanical interlocks.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Provided is a roller shutter-type intelligent garbage can head, including a protective shell, a mounting shell, a sensor, connecting blades and a coupler. A sliding groove is provided between the protective shell and the mounting shell; the connecting blades and a first baffle are arranged in the sliding groove in a limited manner; the sensor is provided at a front end of the protective shell of the roller shutter-type intelligent garbage can head, and a rear end of the sensor is electrically connected to a rotating motor by means of a connecting line; the sensor senses an upper end and controls the rotating motor to rotate stably so as to drive two sets of reel pipes to synchronously rotate under an action of the coupler. At this time, by means of the mesh connection between limiting recesses on the outer sides of the reel pipes and limiting blocks on the outer sides of the connecting blades, the connecting blades and the first baffle can be driven to be stably and automatically wound outside the reel pipes. In this process, the overall convenience is high, the collision between a cover and a hand in a using process can be effectively avoided, better use experience is provided, and the applicability of the device in a narrow space is improved.
