Solution Overview

Problem

Existing inserting apparatuses, such as endoscopes, face challenges in improving resistance against physical shocks due to the weakness of the cover that closes the lever housing section, which affects the durability and reliability of the device during repeated use.

Innovation Solution

The design incorporates a base with a recessed first surface, a movable member, a tabular lid member with a contact surface larger than the opening, and a fixing resin between the lid member and the base, along with protrusions for enhanced strength and stability, ensuring secure attachment and improved resistance to physical shocks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a thin tabular cover is used to close the lever housing section, then the device structure remains simple and compact, but the strength and resistance against physical shocks deteriorate

Engineering Contradiction:
Improvestructure simplicityVSAvoidcover strength
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The patent applies composite materials by combining the tabular cover (resin material) with fixing resin to form a composite structure. The cover itself remains simple and thin, but when combined with the fixing resin that penetrates into the cover and base, the overall structure achieves high strength and shock resistance while maintaining structural simplicity

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent merges the cover, base, and fixing resin into an integrated composite structure. The fixing resin acts as a bonding medium that merges these separate components into a unified structure with enhanced strength, resolving the contradiction between simple structure and high strength

Inventive Principle:
Principle #5Merging (Combining)

2Volume of moving object

If the cover is made thinner to maintain compactness, then the device remains compact, but the durability during repeated use deteriorates

Engineering Contradiction:
Improvedevice compactnessVSAvoiddurability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The thin cover maintains compactness while the composite structure formed with fixing resin provides the necessary durability. The resin material of the cover remains lightweight and compact, but the composite bonding with fixing resin ensures reliability during repeated use

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The fixing resin provides beforehand cushioning by creating a shock-absorbing bonding layer between the cover and base. This protective bonding structure is prepared in advance to withstand physical shocks and stresses during repeated use, preventing damage to the thin cover

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

3Strength

If the cover strength is improved by making it thicker, then resistance against physical shocks improves, but the device size and complexity increase

Engineering Contradiction:
Improvecover strengthVSAvoidstructure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

Instead of thickening the cover, the patent uses composite materials to achieve strength. The thin cover combined with fixing resin creates a composite structure that provides high strength without increasing the cover thickness or overall device complexity

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent shifts the strength enhancement from the thickness dimension to the bonding interface dimension. Rather than making the cover thicker in one dimension, the fixing resin strengthens the structure through the bonding interface between cover and base, maintaining compactness while achieving high strength

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
