Solution Overview

Problem

Existing shock absorbing members require an additional member to be attached to a recessed portion of a product before mounting, which is inconvenient and inefficient.

Innovation Solution

A shock absorbing member with a support part and a movable part that can move into a recessed portion, coupled by a deformable coupling part with arm portions, allowing the movable part to adjust its position without needing additional attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a support part is used to support a side of a product, then the product can be supported, but when the product has a recessed portion, the support part cannot support the side properly and requires an additional member to be attached

Engineering Contradiction:
Improvesupport reliabilityVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The support part includes a movable part that can dynamically change its position between a retracted state (when the product does not have a recessed portion) and an extended state (when the product has a recessed portion). This dynamic capability allows the same support part to adapt to different product configurations without requiring additional members, thereby resolving the contradiction between support reliability and structure complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable part changes its positional parameter between two states: retracted and extended. By changing this positional parameter, the support part can accommodate products with or without recessed portions, eliminating the need for additional members and reducing structural complexity while maintaining support reliability.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If a movable part is added to the support part to enable it to move into a recessed portion, then the support can adapt to products with recessed portions, but the structure becomes more complex

Engineering Contradiction:
Improveadaptability to recessed portionsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The movable part is integrated with the support part to form a unified structure. The coupling part connects the movable part and support part, merging their functions into a single shock absorbing member. This integration allows the support part to adapt to products with recessed portions without requiring separate additional members, thereby improving adaptability while minimizing the increase in structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The support part with the movable part serves multiple functions: it can support both products with recessed portions and products without recessed portions. The movable part can be positioned in different states (retracted or extended) to accommodate different product configurations, making the shock absorbing member universal and eliminating the need for multiple different support parts.

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

3Device complexity

If the movable part is always positioned outside the recessed portion, then the structure is simpler, but it cannot provide proper support when the product has a recessed portion

Engineering Contradiction:
Improvestructure simplicityVSAvoidsupport capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The movable part is designed to be movable rather than fixed, allowing it to dynamically adjust its position based on the product configuration. When the product has a recessed portion, the movable part extends into the recessed portion to provide proper support. When the product does not have a recessed portion, the movable part remains retracted. This dynamic design maintains structural simplicity while ensuring support capability.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If the movable part juts further outward than the outer surface of the support part, then it can easily move into the recessed portion, but it creates obstructions when not in use

Engineering Contradiction:
Improveease of movement into recessed portionVSAvoidobstructions
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The movable part dynamically adjusts its position between a retracted state (flush with the outer surface of the support part) and an extended state (jutting outward to enter the recessed portion). When not in use, the movable part is retracted to be flush with the outer surface, eliminating obstructions. When needed, it extends to easily move into the recessed portion, thus resolving the contradiction between ease of operation and harmful obstructions.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Eliminates the need for pre-attachment of additional members, enhances stability and ease of mounting, and reduces obstructions by allowing the movable part to fit seamlessly into recessed areas.

Implementation Method 1

a coupling part that couples the support part and the movable part to each other and deforms to allow the movable part to move into the recessed portion

Methodology Applied
Scientific EffectElastic deformation: Elasticity

Implementation Method 2

the acting part includes a pair of arm portions coupling, to the support part, a first end portion and a second end portion of the movable part in an intersecting direction relative to a movement direction of the movable part, formed into an arc shape in plan view, and configured to exert the moving force by using an elastic force
