Portable work surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable work surfaces lack versatility and efficiency in transitioning between mat and bag configurations, particularly in work environments, where they fail to effectively store and transport tools, accessories, and debris without occupying space or being tampered with.
Innovation Solution
A portable work surface with a body comprising a central and peripheral portion, a gathering means with a cord, and a cover hingedly connected, allowing for a planar mat configuration that converts into a compact bag configuration with rigid members for concertina folding and a cover that can be stood upright to attract attention, featuring fluorescent and reflective materials for visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the mat is converted into a bag configuration for storage and transport, then space efficiency and portability are improved, but accessibility and ease of use during work are worsened
Solution Approach 1:
The mat employs dynamic convertibility between flat and bag configurations through a gathering mechanism with cords and elastic members. This allows the structure to transition from an extended work surface to a compact storage bag, optimizing both accessibility during use and portability during transport without requiring separate tools or containers.
Solution Approach 2:
The mat is divided into functional zones including a central work area, peripheral gathering zones with cords, and elastic member attachment points. This segmentation enables selective folding and gathering of specific portions while maintaining structural integrity, allowing efficient conversion between configurations while preserving accessibility to stored items.
2Ease of operation
If the mat is left open in a work environment, then accessibility and ease of use are improved, but risk of tampering and loss of items is worsened
Solution Approach 1:
The mat serves multiple functions simultaneously: it provides a flat work surface for activities, a containment structure for storing tools and accessories, and a secure closed bag for protecting contents. The peripheral portion can function as both an extended workspace and a protective barrier, reducing tampering risk while maintaining accessibility during work.
Solution Approach 2:
The mat creates a nested containment structure where tools, accessories, and debris are stored within the enclosed space formed by the peripheral portion. This nested configuration protects items from tampering and loss while keeping them easily accessible during work, eliminating the need for separate tool bags or containers.
3Strength
If the peripheral portion is made rigid for structural support, then strength and stability are improved, but flexibility and ease of folding are worsened
Solution Approach 1:
The mat employs local quality differentiation where the central portion maintains flexibility for comfort and folding, while the peripheral portion incorporates rigid members for structural support and shape maintenance. This localized rigidity enables the peripheral section to stand upright and maintain bowl-like shape when partially folded, without compromising the overall flexibility of the mat structure.
Solution Approach 2:
The mat utilizes parameter changes in material properties, combining flexible fabric materials in the central portion with rigid members in the peripheral portion. This parameter differentiation allows the structure to transition smoothly between configurations, maintaining both strength for structural support and flexibility for ease of folding and gathering.
4Object-affected harmful factors
If the mat is made highly visible with fluorescent materials, then attention attraction and tampering deterrence are improved, but aesthetic appearance and professionalism are worsened
Solution Approach 1:
The mat incorporates fluorescent and reflective materials that change appearance based on lighting conditions. During low-light or emergency situations, these materials emit bright visible light for high visibility and tampering deterrence. During normal daylight conditions, the materials maintain a more subdued appearance, balancing safety requirements with aesthetic considerations for professional work environments.

AI summary
A portable work surface is convertible between mat and bag configurations, and includes a body with a central portion and a surrounding peripheral portion, with a cord threaded at least part way around the peripheral portion. The central and peripheral portions are configurable to define a substantially planar mat configuration. The cord is operable to fold the peripheral portion about the central portion to define a bag configuration where the central portion defines a bag base and the peripheral portion defines a bag wall. The peripheral portion comprises rigid members spanning the distance of the bag wall substantially between the central portion and the cord. In an embodiment, a cover may be hingedly connected to the body, foldable to straddle the peripheral portion in the bag configuration, and configurable to protrude proud of the planar mat configuration of the central portion and the peripheral portion.
