Solution Overview

Problem

Current solutions for bench backrest covers lack effective protection and fail to provide a clear advertising space, often creasing or flapping in the wind, and are not designed for easy use or low production costs.

Innovation Solution

A cover designed to be slipped over the backrest of a bench, featuring a longer rear surface connected to a shorter seat-facing surface via side parts, ensuring a snug fit without creases, providing protection and clear advertising visibility, while being easy to use and cost-effective.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cover is made to fit tightly on the backrest, then protection and advertising visibility are improved, but the cover becomes difficult to install and remove

Engineering Contradiction:
Improveprotection effectivenessVSAvoidinstallation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cover is made from a flexible textile material that can be stretched and molded to fit the backrest contours, then easily removed and reused. The flexible nature allows the cover to maintain tight contact for protection while being simple to install and remove.

Inventive Principle:
Principle #30Flexible shells and thin films

2Loss of information

If the cover material is made smooth and taut, then advertising visibility is improved, but the cover loses comfort for leaning

Engineering Contradiction:
Improveadvertising visibilityVSAvoidleaning comfort
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The cover employs different surface qualities in different areas: the front surface facing viewers is kept smooth and taut for optimal advertising visibility, while the rear surface contacting users is designed with softer, more compliant characteristics for comfortable leaning. This local differentiation resolves the contradiction between visibility and comfort.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If the cover is designed as a single piece, then production costs are reduced, but the fit and protection effectiveness worsen

Engineering Contradiction:
Improveproduction costVSAvoidprotection effectiveness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The cover is divided into multiple sections or panels that can be separately manufactured and then assembled. This segmentation allows each part to be optimized for specific functions (protection, comfort, visibility) while maintaining overall integration, achieving both cost-effectiveness and effectiveness.

Inventive Principle:
Principle #1Segmentation

4Reliability

If the cover sides are made longer, then protection coverage is improved, but the cover creates more creases and folds

Engineering Contradiction:
Improveprotection coverageVSAvoidsurface smoothness
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The cover design incorporates curved contours and rounded edges that follow the natural shape of the backrest. This curvature allows the material to drape smoothly without creating sharp creases or folds, while still providing extended coverage for improved protection.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

The invention relates to a cover for benches. The cover is designed to be pulled over the backrest of a bench, comprising a seat-facing surface and a longer rear surface, the seat-facing and rear surfaces being connected to each other on the left and right by two side panels, and the cover having a substantially planar cut. This cover provides protection for the backrest of a bench and for the occupants from drafts in the kidney and buttocks area, and also generates additional advertising space, for example, on benches in sports halls or on sports fields.
